Which R2R DAC UP TO 1K: ORGANIC, FULL-BODIED, DEEP SOUNDSTAGE


Hi all and hello George,

I`m new to Audiogon and as I have seen from earlier discussions some of you seem to be THE absolute R2R enthusiasts for many years. May I ask you for some help regarding this topic as I`m out for a new dac which should be R2R?

I`m coming from a Lector CDP 707, which is sold now as I got over to streaming, but I bloody regret it. The Lector had all I ever wanted, tonally he played on the warm, full-bodied side, organically with a lot of flesh to the bone and authority/slam and I loved the expansive soundstage, not overly wide but very deep. Bass was punchy enough even for EDM which I listen to mainly.

For the moment I`m using my former headamp as a DAC, the Questyle CMA 600i, with a DS chip on board, AKM 4490. I wouldn`t call it a catastrophe, but of course the signature is lightyears away from the Lector.

When looking for a new DAC I saw that Lector Strumenti offers some too, but I`m afraid my budget is too small with up to 1K, so this is not an option.

In respect of the Lector using the PCM 1704K I thought about (ab)using some vintage gear, for examle the Denon DVD 5000 with 4xPCM 1704J on board too (the Denon has a digital input and could be used as a stand alone DAC too), but I was told the analog stage is crappy and so I got away from this.

Still on my mind is the old Naim DAC and the Bifrost 2 or a used HoloSpring but for the moment I got no possibilitys to test them in my system (I`m using a tube packed preamp and as a headamp the Emotiva BasX 100 with the jumpers set as my "heddphone" requires some juice) and sure I`m open to any other ideas.

So, what would be your favourite devices when looking at my desired sound and knowing what (tiny amount) I got to spend?


It should be able to handle 24/96 btw, but my main concern would be an extremely deep and wide soundstage and a darker organic tonality.

Would be really glad for some help and input.

Best regards
Michael

Yes Michael, your Lector you should have kept, as it had the best R2R chips, 2 x PM1704-K "K" being selected and a cheap easy to get SF-HD65 laser.
These PCM1704 and the 1702 were the best and last of the R2R Multibit dacs chips made. Now they’re all discrete R2R Multibit some better some worse.

My Linn CD-12 had 4 of the PCM1704K’s in it with a great sound, full bodied yet tight and very dynamic, great boogie factor.

Your on a budget, to get back into that sound cheaply try to hunt down a Cary CD-303-200 it has the PCM1704’s and the very good PMD200 HDCD filter chip and uses the VAM1202 laser still obtainable nice and cheap should you ever need one. https://www.stereophile.com/cdplayers/504cary/index.html
Or even a California Audio Labs CL-15 https://www.stereophile.com/cdplayers/1198cal/index.html but the laser  RAE0113Z is also getting real hard to get.

That Denon yes uses the PCM1704 but the lower PMD100 HDCD filter chip, and it’s laser VED0378 is getting well over $100 and hard to get.

I now have a MSB discrete R2R and love it.
R2R conversion done right just has a real live rich sound, unbelievable on good recording. But it "can" give you warts and all on the real bad ones.
Where DS (delta sigma) to me is smooth and is better for bad recordings, but at the sacrifice of being just a bit of a yawn on the good ones, but it does DSD and SACD that’s what it’s good for.

Cheers George

If you can find a used Yamamoto YDA-01 that could be your ticket. I was lucky enough to find one right at your price point, actually.
Thanks a lot for the first ideas!

@georgehifi I just found one Cary 303 through hifishark but it doesn't have a digital input. Nevertheless the reviews sound promising. The CAL' s reviews seem to be fitting too. Found one in Austria, while I'm from Germany, so not a big deal. But the price is 650 EUR and so I'm asking myself if it can compete with the newer dedicated R2R dacs, as Naims from 2010 or the actual Bifrost 2. What do you think about this? 

@devilboy Never heard of Yamamoto but I will definitely have an eye on this. Really could be worth a try. Could you maybe say some words about the overall tonality and it' s ability regarding soundstage, macrodynamics, imaging and layering?

Thanks again!
