Thank you for making this video.. exactly what i needed to know for my older receiver and trying a new preamp to see if there is any improvement or not. Thanks !
You're right :), few years back I got hold of a surprisingly excellent sounding little pre-amp, a Technics SU- C01. This thing is small but sounds wonderful and has gold plated connectors as well. Got it for only 8,50 pounds :)
Thank you for this suggestion. I am using a Marantz PM8100SA as the pre-amp and an Onkyo Integra A-7 as the power amp. I am using Diatone DS500 speakers. Simply beautiful sound.
I'm going to try this trick with a NAD 3240PE I found. The pre-amp section of my AU-317 is a bit unstable. Tone defeat not working or only on one channel. Bass from right speaker much weaker half the time. It needs work, but all the people refurbishing vintage gear seem to have quit because work just became too much in Covid times.. Hope to see you back soon Kelvin!
It's amazing how few TH-cam instructional videos actually turn the equipment around to actually show the actual "how to connect" visuals - and, as such, this video helps to fill a void not properly addressed by the many other misleading [instructional??] videos - which are mainly vanity videos without any actual information. Although I have vintage McIntosh equipment [C 28 Pre-amplifier (1973)/MC 7270 amplifier (late 1980s)] I find this video still to be informative. I guess that all of the videos of the MC 7270 avoid showing the actual cable hookups as the real intent is to visually brag about the appearance and the sound. While OK, wouldn't it be nice to provide the occasional instructional hookup video that actually addresses what the title header is stating. Again - thanks for this video. In addition to "picture-is-worth-a thousand-words video examples, connections, we need serious advice on the proper grounding of high-powered vintage amplifiers [mine is 270 watts-per-channel] and best grounding practices for high-end equipment plugged into pre-amplifiers [ground all devices into the one pre-amplifier ground? [some videos appear to have the owner literally dancing around his amplifier to the music - - hardly the instructional video the header [title] would imply. Again - thanks to "Stereo review X."
I’m using a parasound P6 preamplifier and Dac, as amplifier I use a marantz 2330b , the sound is great , much better than using the marantz as receiver , greetings from Ecuador
Great video. Just to ask whether I can connect my musical fidelity A3 integrated amplifier to a power amplifier. There is a pre amp. out on the A3 integrated amplifier. The power amplifier seem not turning on so I thought of buy a power amplifier to connect to the pre out .
Hello , thank you for sharing all these infos. I do have tricky question for you. Is it possible to bind 2 power amps together ? I would like to bind my M80 with another one is that possible I’ve read it is.. but how ?
Hi.. I own a sansui au 717 I want to use it as a preamp ... on the back is a slide I have to set if I separete the poweramp from the preamp... but I have to make a choice between direct coupled or capacitor coupled... wich to choose... thanks already Robert...
Thanks, Kelvin... for another useful video. To add warmth.. you could experiment with feeding your Eight Deluxe with a tube preamp like the Dynaco PAS3.. or the more modern Quicksilver or Audible illusions models.
I own a Sansui 2000X which is my favourite vintage amp. I recently bought a Sansui AU 317 in a clearance sale but was disappointed v the older amp. It’s been sitting on the shelf unused. However thanks to this tip though and the combination sound even better than the 2000X. I knew you could do this but had no idea it would deliver this sort of improvement. I’d be interested to hear your views on how the Sansui Eight Deluxe compares to the 2000X?
Jon Stannah hi Jon i’m glad you got a good result combining those two now regarding the eight compare to the 2000 X The truth is I’m in the world of guesswork clearly the eight goes for more money and I think the eighth is younger. I’d be very surprised if the 2000 sounds better than the eight particularly in the power amp department. That’s my best guess anyway. Cheers K
Turn table signal isn't just very small it also has very little bass (because bass frequencies would otherwise make the tracks super wide and you'd fit less music on a single or lose resolution in the higher frequencies) so you the phono pre-amp also reverses this to get the original flat signal of the recording.
I have a Pioneer sx-780. Can I run my turntable to a phono preamp and then that phono preamp to a Aux Line In on the Pioneer to bypass the phono preamp built into the Pioneer?
THE MAIN REASON THEY MADE THOSE THAT WAY IS SO YOU CAN HOOK UP 2 OR 3 MAIN AMPS. BY PUTTING A Y ADAPTER ON PRE OUT AND HOOK UP 2 AMPS OR MORE. Or If YOU NEEDED MORE INPUTS YOU CAN HOOL UP 2 PRE AMPS INTO ONE AMP.
I want to use NAD 319 (125wpc) like pre amp (becaise he have remote control) and Marantz 1150d (75wpc) like power amp. Is that a problem? I mean , in this case pre amp is stronger then power amp. Tnx
Thanks. I see the main and pre on the back of my Sansui 3300. I was thinking of adding a pre amp to my system. I noticed a power main switch and a power amp switch on my Sony reel to reel. If I plug that into a pre amp, would I also switch on the power amp on the reel to reel? G
Which volume control do you adjust? I know a lot of dedicated power amps don't even have a volume control, which leads me to believe that you would only use the volume control on the preamp, but maybe with your setup you would do things differently? Leave the pre at 100% and only adjust the sansui volume? Some "sweet spot"?
The volume is on the preamp. If the power ramp had a volume it would have its own preamp Cheers K Interestingly I have plugged my iPhone (Spotify’s) straight into the power amp so you then use the volume on your iPhone is the volume
I have a TFM-25 amp & CT -17 preamp 1989 . The preamp started giving me trouble and finally stopped working . I purchased a five speaker surround system . I hate to just junk these . The sound was just the best . Anyone think that there is any interest in these components ?
My Rotel A11 Tribute has a pre-out so I understand I could use this simply as a pre amp and use a vintage receiver as the power amp, but with the Rotel's pre-out can this be done the other way around, ie using the vintage receiver as the pre amp and the Rotel as the power amp? Many thanks
I am watching you since I start looking for good vintage receiver for my turntable. So I am now a little worry if sansui 661 will have a good result with my dual 701 and b&o s45-2. and I think that this receiver don't have this option to connect it with another preamp.
Hi! I am new to all this hifi vintage stuff and now i'm having a hard time to connect Akai AA 1030 reciever with Akai AM 2350 amp. Is it possible and if so, how? Thanks!
Not exactly sure what you mean you should be able to connect the tuner to the other Amp But you can’t double up the power or just connect one amp to the other particularly as this doesn’t have pre-power separation I don’t think it Does anyway
what other options would i have since my vintage onkyo 3000 does not have the pre amp out/power in? i have decent sounds from my a or b speakers selection, but when i select the a&b combo selector, the sound gets lower.
You need a volume controlled line out, or it won't work (or your dedicated power amp has to have a volume control). Watch out some amps seem to have these loops but they are marked adapter or processor or something. Those are not pre-amp outputs but for adding an equalizer to the system. All sound will cut out if you put the pre-amp in direct mode.
And when you want to listen to music plug the amp into the electricity, you take the thing on the end of the lead with the three pins and plug it into the corresponding socket on the wall. And then press both power buttons. Easy.
switching on power amp before pre-amp is a bad idea..! please do not take this advice... ! the way to go is..1st-source..2nd-pre...3rd-power..then reverse to shut down !!
Yes this is possible! if you have a pre out connection, on one amplifier, and a main in connection, on the other amplifier! If you have two amplifiers, which both amplifiers, have pre out connections, and main in connections, you can use either amplifier, for this set up!
I am now using my vintage Marantz as a pre-amp and a used Emotive amp I purchased, I have the volume on the amp at max and using the 2230 to control the volume. Am I doing it the right way?
Not sure if anyone can help but I've got a nad 3020a with a faulty speaker terminal and looked at how much of a pain it is to get fixed. Would I be able to use this as a pre amp with another Nad, the C320BEE using the same principle in this vid using the pre in/out to main in ports?
@@stereoreviewx yes its about keeping it there. I'm considering soldering. But it's working well as the pre amp all the same. I can tell there's more drive to it. Nice to see you reply
Yes that’s an interesting question I kind of feel like you can but I’m scared to try. I have plugged my iPhone straight into a power amp it was fine I just don’t wanna recommend it to anyone just in case K
Im confused....the pre amp on top has no tuner? So to listen to fm radio you nee add fm receiver? And you plug turntable cb player into the pre amp and use the pre amp to control which signal it sends to the main amp? is iphone/android headphone jack the same as pre amp output? What about speaker output from a pc? will a phone jack from a pc to rca adapter to the pre amp to the main amp work? And....will a pre amp output work on 2 separate amps?
Ah. So under this system you remove the FM tuner capability? I just purchased a Sansui AU-317 to give this a try. The reel to reel is my main input so I can live with it.
@@stereoreviewx yes your right I did click on about the pioneer after you explained Kelvin,I brought the 3020 after watching your review I love it.which other pre amp should I buy then that would go well with the 3020 Kelvin.
What is the purpose of having a preamp going into a main power amplifier when all the hookups for the turntable and CD player can go directly into the power amplifier/receiver and render great results by themselves?
I have NAD 3080 (1978) PREAMP AND AMPFLIER AT ONCE 90 WATTS SINUS. This machine can destroy speakers of pure 120 watts just like that because i see that in my home..Japanese created exellent audio machines.
I figured modern power amps have much more amperage and better control for to drive modern speakers, so wouldn't you do the opposite? Run the vintage receiver to experience the dials and looks but then a modern power amp like a Bryston to power the modern speakers properly no?
Well, these are hard things to generalise about, But if you want to get to the hire end of Hi Fi, you wanna clean path you don’t really want tone controls lots of switches . I can’t say there’s a guaranteed rule Though
You got the order wrong when you turn on the system, you should alway turn on the preamp first then power amp last, cause you don't want a jolt of electricy coming into the pwr amp from the pre amp .
Wit my $50 preamp your theory is correct (1st preamp/2nd pwr amp - On. BUT reverse order wen pwrng amps Off 1st pwr amp/2nd preamp Off). Wit my $250 preamp this video theory is correct (1st pwr amp/2nd preamp - On. Same order wen powering amps Off ) I ruined 2 woofers incorrectly pwrng up my $50 preamp.
I have heard it said that you can make a normal integrated into a power amp by simply turning the volume all the way up and plugging a preamp into it via aux or CD would this be correct? The person who suggested it was Steve Guttenberg AKA Audiophiliac. He says it here at 3:26 minutes in th-cam.com/video/72S0lmpju1s/w-d-xo.html
Well I Gotta say I’ve never done that also it’s scary he may be right of course someone should try it. What I have done is plugged my iPhone directly into a power amp and use the volume of your iPhone to control the volume I’ve done that many times it seems to work fine but don’t do it on my recommendation you know.K
I bought a new turn table and kept being reminded I will need a Pre amp so I bought one , plugged it straight into aux , didn't think anything of it , until the penny dropped my Nad amp has i written on it Duh. Now im trying the Nad on its own and I can honestly say the pre amp wasn't any better than the Nad on its own. But after watching this video im curios to try plugging the pre amp into the power amp inputs instead of the aux input.
IMPEDANCE MATCHING... Not one genius here mentioned it. Would highly recommended people spend another 10 minutes googling before plugging random pres into power amps. I really like kelvin's videos, but like most audio reviewers, almost 0 technical knowledge.

conversely, it is better to connect a vintage integrated amplifier as a power amp with a new preamp
Hi Khalid, could you explain what you mean? Were you reacting to Tim Wynn explaining just before you about the safest way to turn the system on first?
so the title of the video is incorrect. Should be modern pre amp to vintage power amp
You talk funny
Just like Daniel Craig
Besides if u said "significand sound improvement" - so where is the sound???
Total BS
