You stole Tom Greens voice.

If I listen to my 300B amp 2 or 3 times a day for 45 minutes each time, do you suggest that I leave the amp on during the day or turn it on and off as needed?

whats the difference between ray and apos ray?

That’s a brilliant Cigar - “ Cigars saves lives”.. cheers

Versatility is awesome! So many search for "THE SOUND"... Why not "Versatility of Sound" based on the current mood, desire, or needs? That's whats up.... :)

Puritan PSM156 for sure, I have yet to see a video on how PSM156 improves a vvinyl analog chain. Only have seen its improvement with digital.

Bring both

I really appreciate this channel and the ABX channel for insights on building speakers. But for ABX, I never would have thought of using butcher block instead of MDF. Your suggestion of adding weight to the base of the speaker to address vibrations is something I never would have thought of. This video suggests more food for thought. Instead of a MTWW configuration where I have to put the midrange above the tweeter to make room for the 15” woofers, I should have considered doing a sub/sat system. I’m thinking of MTMs on stands with separate subs. With dual 10” woofers, there should be no issue getting the mains down to 80-100 Hz. Decoupling the woofers from the rest of the speaker addresses vibration and I have the ability to position the woofers in the room as needed. The changes in the design I was thinking of were questionable in terms of impact. This has the potential to actually be worth doing. Thank you!!!!

Did you use an active crossover with the subs you had before? It might help with speed and integration. It’s how I got subs to sound “right” with maggies.

Take both, GR Research OB subwoofers are end game bro

Smoke some weed and everything will fit soundwise 😂

Don't bring too many things, you won't have time to make real good comparison. With the 156 it should be a "yes" or a "no" right away so no time consuming I guess + the Frankenstein DAC (but explain all the modifications made).

This video gets even better each time you watch it. 🤠

In my system I cleaned up the power to each component first and, after that I didn't think the DAC or anything needed upgrading 😂😂😂

Sorry but I quite do not understant your statments about neutrality. Isnt the music mastered in purpose to be fun without V added by amp? Isnt electrocompaniet, hegel which are not V, fun to listen? Why you did not add your percived V intensity of this amp? I truly belive this amp is great but that V shape is a bit holding me back as i have to purchase off shore. Could you compare it to somthing?

Ladybugs!

DAC w cables & barley pop 😊

You've got skills, build the GR Research open baffle subwoofer kit! You'll get 20 Hz unless your room has too many problems. I've got them and love them.

Puritan

why don't you bring your tube gears?

Definitely take both. Like you say, start with the phono stage then successively add the rest of his system-that would be interesting. The DAC comparison would be illuminating too. You're content is getting ever more interesting the more experience you gain. Thanx for the postcards from down the rabbit hole.

I'm in a conversation currently with someone who is claiming that all non load dependent amps sound the same. So ive asked this person "whats the cheapest non load dependent amp?" And if its the case that all non load dependent amps sound the same wouldn't everyone just own the cheapest one? The answer i got was people have unchecked biases and will pay for how something looks. Does anybody have any literature on this?

Happy Canada Day 😎🇨🇦

Didn't come here for the cigar Carry on...

The Dac!

Both 156 and Dac

Sounds like you are in the need for detailed bass. I have been using for the past 25 years is a cone shaped housing with it’s back and inverted cone with a Dacron ball in the 3 inch port which is 1 inch deep. The exact opposite to open baffles. You want zero resonance in the housing.

Bring both, Loic !

Bring the puritan and the dac.

Here’s the real kicker of a question: is it clean power or the DAC components (the clock circuit primarily) not being engineered to the appropriate tolerances and isolation? ;) 2 W21s in a side by side Z baffle is on my radar for year-end projects. Along with grabbing a sound integrity 24 for a super small sealed enclosure with a 50hz lowpass to test out.

Give him clean power bring the Puritan psm-156💪

Be inspired by Trading Places, have both.

Thank you for the discord chat!

Not sure, but you can mail that 156 to Cape Breton for a test!😊

Do I use the Puritan psm156? Do I use my custom dac? W21 bass Driver: liisong.ca/collections/bass-drivers/products/w-21

Hello sir! Wonderful cigar!!! I will say both, but try the power conditioner first. 😉

As per Dave’s system…….., I didn’t spot anything on any of his videos which speaks to the same volume of what’s heard briefly through your system, I only wish you’d make a effort to include a list of the artist and tracks you’re playing on your videos, one jazz lover to another.

This video affirms some of the decisions I made on my own speakers. They are being built using 1.75” thick butcher block. The ONLY reason it isn’t thicker is because thicker butcher block was not readily available. For the woofer portion of the baffle, this is reinforced with an added layer of .75” MDF on the back. We may end up using two MDF panels. The original design called for cutting the speaker out of either 3.25” or 3.5” solid wood (the designer either has or has access to a fancy CNC machine). You mentioned the upper bass range reproduction. My designer was going to do a 2-way speaker. However, in testing the design, he found that the bass was lacking in the 300-600 hz region. His solution was to change to a 3-way design to allow for a woofer whose sole job was to reproduce sound from 1200 hz to 200 hz. There is a first order passive crossover at 1200 hz and a 4th order LR electronic crossover at 200 hz. I want to push back a bit on bi-amping. It depends on the design. IMHO, most 3-way designs will benefit from bi-amping the woofer. The original design of my speaker was a passive 3-way with a single 15” woofer. I changed the design to use dual 15” woofers so bi-amping became a no-brainer. However, this designer has back loaded horn designs using high efficiency woofers (around 98db). Would I bi-amp a design like this? Probably not. My final point is a fact that gets FAR too little discussion: the best location for bass is usually not where the rest of the speaker is located. So I can get a so called “full range” speaker that gets down to 20-25 hz in an anechoic chamber that may not perform well or has a serious peak in the bass which is solely the product of room geometry. Especially if the crossover to your woofers is at or below the point at which bass becomes omnidirectional, you are better off having separate bass cabinets that you can position in your room as needed. Room geometry is the reason why there is little dispute over using EQ in the bass region. If you don’t have separate bass cabinets, EQ is usually the next best thing for good in room bass response.

Hello. Just through half of this and it is appreciated. I will be taking your advice to heart. Whatever, I have used Eminence 15"Cx with cast basket in open baffles, and, you need to have the extra thick solid wood panel. I wonder what you will say, then, about more complex music played. Give is some outside curve, maybe a deep cutout like in this speaker to broaden resonance. You have a lot of guitars, eh, don't you? 🙂

When using traditional sealed subwoofers I have used an external high pass filter to send 90hz to my mains and then used the subs low pass filter at about 70 to 80hz with a 12 db slope on each. It sort of filled in the gap between them nicely because of my traditional subs high output. From the research that I'm currently devouring, it seems that when both drivers are open baffle (the subs and the full range), that the crossovers can have some overlap, sometimes substantial in order to get a nice blend. Here in your example I see that you have a shared 20hz frequency between the two drivers and values that are closer to traditional box speakers and subs. In other open baffle designs, I've seen seasoned builders like yourself letting the w15 run at crossovers settings ranging from 150hz to as high as 500hz. The same could be said for the factory built leonidas and the macara speakers. However, all of those systems had both drivers placed on one baffle whereas you have moved the subs away from the main drivers. Is that why your crossovers are closer to traditional values? Desperately try to learn here. Thank you!

I can relate to the enthusiasm heard during your discussion. I am the same way when I talk audio. This is a fun listen.

I'm so tired of you talking about your open baffle speakers! So, I'm doing something about it. I just ordered the drivers to build my own. I can do the woodworking. I have no idea about crossovers. So, I'll be asking for help from the hifi community.

Ha! You nailed Harley, in the kindest way. I hope he gets a kick out of your review and impersonation.

where do you live in canada?

Happiness Is Easy, by Talk Talk, as well as Does Caroline Know?, and Mark Hollis self titled album is a must-own. And ideally selecting speakers which fit your room, followed by a synergistic amp which matches them tonality wise as well as offering the proper amount of current, versus raw power rating is more important. Yet if your electronics aren’t getting said current draw ( right gauge of power cords ) then said electronics aren’t being driven or heard to their fullest potential, cabling ( especially the right flavoring) matters just as much, and never overlook the importance of the connectors themselves.

As someone wrote earlier on, each one of us have a deep bedded perception on what sounds, as well as feel correctly balanced to us. Logically friends and associates of mine whom are more accustomed to older recordings or amplified music, can’t really understand the beauty of which jazz or classical recordings have to offer. I’ve taking the time to understand what has the capability of moving me to tears, if it isn’t engaging?, why bother at all?……., said time it takes to understand the sound signature of each component is vital in how the final voicing as the system collectively counts more than simply allowing oneself to be drawn into mere sound, as opposed to learning to hear deeper into the music itself, bass doesn’t not a system make, if it’s boomy, there are very few ways of restoring said balance once it’s lost. Unless one’s recordings are strictly geared towards pipe organ recordings?, I’d say please thy self above all, o4 anyone else. Knowing which brands of tubes do what also counts, say for example while NOS Black-plate RCA | Sylvania preamp tubes in tandem offer some of the best vocal shading I’ve encountered to date, Raytheon is more geared towards low end impact, while lacking in other areas, seek out brands like Lorenz ( Germany ) | Thompson-CSF or Mazda Black-Plate ( both from France ) | NEC and TEN Kobe ( both from Japan ) and than understanding that balance versus noise is the key objective. The extra bass impact you’re referring to by doing an array of 3 bass drivers of subs isn’t necessarily the best path to pursue……, dude in the end, you’ve to satisfy yourself above anyone else, least you have lost your own individuality. Just food for thought.

Question for Dave, did you go to Roslyn school? You look like Someone I used to know. Andrew McCrae. Mtl

Hall of Fame Status🎶👌🏽🔥🎶 I think I would love the Sibelius too. Such a GREAT video, fun, entertaining, true to point👏🏼👏🏼 and Harley is a gem 💎

diy is fun, take a lot of time. but only passive subwoofers and kit class d power amps are worth it.
