Glad you're enjoying it. Watch my other video. I think I ended up bypassing the JFETs.

Very different amps. The Stereo 70 has a valve-like warmth and sweetness that most transistor amps do not.

Great! My Ortofon OM5E stylus has just broken. I could replace the stylus, but I am thinking about going with a Nagaoka MP-110.

@@audionautica6843 Nagaoka is 150-300 hours of useful life, Ortofon 10 is 300-500, Ortofon 20 is 800-1000 hours. Nagaoka has a very small capacitance amplitude, 100-200pF. While Ortofon needles can work well between 200-500 pF. Nagaoka has a separation between channels of 20 dB. Ortofon 20 is 25 dB, and Ortofon 10 is 22 dB. But Nagaoka's main problem is compliance, which I don't recommend for low mass arms.Nagaoka is 18 µm/mN. Ortofon is 25, perfect for your arm. Ortofon are the best stylus for low mass duals tone arms

@@audionautica6843 The Ortofon 10 and 20 have a longer lifespan, according to the manufacturer, than the Nagaoka. The Ortofon 10 and 20 have higher compliance, which makes them perfect for low-mass tonearms (such as the Dual CS505). The Ortofon 10 and 20 have a greater tolerance for capacitance than the Nagaoka. The Ortofon 10 and 20 also offer better channel separation. I don’t think there’s a better cartridge for a Dual CS505 than the Ortofon 20. And if you’re on a tight budget, the 10 is excellent.

Thanks so much for this, it is really helpful. It looks like there are some good discounts out there on the 20 - this should fit straight into my OM cartridge. Looks like it isn't possible to buy the Super OM cartridge without a stylus in it, although my other deck is a Rega RP1 which comes factory with an OM5E fitted, so I guess its about time it had the stylus replaced. Win Win!

Sorry, I didn't catch his name.

I hope you learn from my mistakes!

Yep.

I'm so glad you found my channel. Make sure you check out my other videos.

I'm not familiar with your Yamaha amp, but I would suspect the Yammy would probably perform better than the Quad. It really depends on the kind of sound that you are looking for. The Tannoys would I imagine have a would have a pretty English mellow kind of sound. Maintaining that theme I think the dynaco would be a good match. But both the Yamaha and the Dynaco are great amps, but very different also - beauty is in the ear of the beholder and it really just depends on what you like the best.

Thank you again The Jazz Kings!

Yes, there's all sorts of options out there - Google is your friend.

Thanks for commenting - I've got a few other repair videos up that you might like to check out.

That's kinda like saying a BMW 5 series has nothing in common with a BMW 3 series. Completely different speakers yes, nothing in common, no.

Thanks - I checked it. It's fine. Might be a low mileage unit.

Fair comments. I honestly cannot remember.

Well as you already know because you've done this yourself, there is a significant risk in importing this kind of gear from overseas, and the return on that risk is getting to know reliable suppliers and how to reduce that risk. I've had to work really hard to develop that knowledge, and I'm not comfortable just giving it away. Happy shopping!

@@audionautica6843 I actually have found a really decent supplier for tonearms, I look at some of the items as I receive them and a 45 year old Tonearm looks and functions like it was made a few days ago!

Good one!

Whatever works - my SYMEF amplifier build was inspired as a cost effective way to have something inspired by Accuphase - I won't call it a clone because it isn't.

@@audionautica6843 lol i guess most germans have the guts to buy these clones for review, i don't see a whole lot of english reviewers out there doing clones. I got the 1969 class A clone and fm300a and was blown away

I hear you!

Cool! Yeah, I wandered around HiFi shops in the early nineties drooling over this sort of stuff and never being able to afford it.

Good one!

I guess so

It sure is!

Yep - that's it. It's a great review. As I said, I'd already ordered mine from Japan when I saw this review. At 13:04 he said "it alters everything that goes through it". With 3 years of listening that has not been my experience, and as I said, a pre-amp should change nothing except for gain - unless one is particularly wanting to change the tone which is what tone controls are for.

I think what he meant to say there is that it gave him understanding what a great preamp should sound like (not the best choice of wording). But who knows...i left him a comment asking about it. Thank you.

Sure is!

I'm sure it would be doable - I could just put knock in inserts on the bottom side and screw the spike in there. However I would suspect I might be dabbling with diminishing returns. If you watched carefully you would note that the room is seriously compromised as a listening room - speakers in the corners with one halfway in a doorway - there just isn't anywhere else. :-( I certainly have noticed a big difference with these stands in a) getting them up off the floor b) substantial decoupling from the floor at bass frequencies - it is much much better than it was with those big speakers sitting directly on a timber floor. Thanks for your comment!

@@audionautica6843 You're right, suspended timber behaves in a much more "lossy" and unpredictable manner. Even the speakers destined for the American market tend to have a higher Q & resonance frequency to compensate. In my previous setup, I have had some success with marble slabs, about 3inches tall and slightly larger than the bases of the speakers. I had placed thin strips of compliant rubber between the slabs the speakers and thicker ones between the floor and the slabs. You could feel the slabs vibrating, almost like a pendulum on spring, but transmission to the floor was much diminished. The slabs were around 40kG each, bit less, than the speakers.

Thanks for your comment, I really enjoyed reading it. This was my first purchase from aleado - possibly not the last, although I think my system is nearing completion (ha!). It was a nerve wracking experience, but seems to have turned out for the best. Yes - freight is a massive expense. AUD 700 just on freight for this amp.

I did and I have, but I will check it again...

You DAC looks quite interesting, and I see it has an I2S input. So to answer your question we need to think about where your music actually comes from, and how it gets into your ears. So what we have now is this: Internet (Qobuz)->laptop->USB->Dac->Headphones. So effectively all your laptop is doing is converting Qobuz from the internet into USB to get it into your DAC. The problem is that USB is a terrible interface for clock reliability. The best interface for a DAC for clocking perspective is I2S. Now I have to say firstly I think the single biggest thing that matters in musical enjoyment is that you are using Qobuz. Just changing from AAC or MP3 files to Lossless files and changing nothing else makes a HUGE difference. Hopefully you have already noticed that. So I don't think that you are going to get an astronomical improvement. But you will get an improvement by improving the digital signal going into your DAC so as to minimise jitter etc... You could do this by using the same hardware I am using, or there are other ways of doing it. I am using Tidal, not Qobuz. I am running Volumio on my Pi Raspberry board, and I am pretty sure it supports Qobuz instead. So what you would do is not use the laptop anymore, but use the streamer, and so what you would then have is this: Internet (Qobuz)->Steamer->I2c->DAC->Headphones Now the noisy USB interface is gone and you have a high quality I2C interface to your DAC. You would need to check the pinouts are the same from the streamer to the DAC!!!! I hope this is of help.

@@audionautica6843 First of all thanks for taking the time to awnser me, you got everything I try to do, so yes I know I2S is better than usb, the question is, how do I command the raspberry pi and make it play the music I want? with my pc? my phone? but then I have to use usb right? that's what I dont understand. Thanks again for your time (btw my usb on the R28 NOS has galvanic isolation)

@@mickouzz It will depend on the software you have on the raspberry pi. I have Volumio, and it has a Tidal/Qobuz connection. So I open up Tidal on my iPad, and tell it to connect to Volumio. So I control the pi rasberry through my iPad. But it has nothing to do with the signal chain - it just tells the pi rasberry what music to play.

@@audionautica6843 ok huge thanks, btw do you know if that works for PC ? I don't have an IPAD and it would be easier not getting my phone full of music :D (I use the offline dowloaded files from qobuz,)

@@audionautica6843 ok huge thanks. so your ipad is comanding the pi to play the music with bluetooth? or what ever usb connection? Do you think it works with windows? I would like not to use my phone (dont have an ipad) so I dont have to download all my qobuz offline library in to my phone which would be anoying. otherwise great news!

I've never tried that - I'll have to give it a go.

Yup - I made this video 2 years ago and I think I have just about gotten over the trauma.
