Where are you going to from TDA? If not a secret...
I have 3x TDA DACs and might try something else for fun too, something not delta sigma based...

@jotom750,
I'm not one that gets too deep into "reviewing" my diy audio gear. I build and listen, then tweak if needed until the foot is tapping and all smiles.
I'm not a TDA guru by any means, but over the longterm, my AD1862 builds seemed to have more foot tapping going on with bigger smiles.
Not a very technical answer 🤣
@ghettocowboy,
I do not have an S1 in my stash, but have always been curious about the 1541A thats installed in my Philips DFA-980. Rumor is it's an S1 chip.

Thanks Vunce. Having a few TDA machines, and having done some very basic mods, (clock, PSU, op amps, caps mostly, I can say that they can make a vast difference. Original implementation is most important though as the more technically minded (not me) know all too well.
Not wishing to upset anybody, but I've not got on with the Marantz CD80 (S1 chip) or the Marantz CD7 (2 x S2 chips) but do like the Cambridge Audio early players, and some others (using the Taiwan chip), my findings are that you can do as much as you like to extract detail from it with very little risk of making it harsh in any way, but with the advantage of extra some detail.
It would be interesting to compare with the AD1862. (Is that in any way similar to the BB PCM 1702?)
All the best.

Hello,
Nope, the AD1862 is way better than PCM 1702 (and 1704) as far my ears are judges. I still prefer my S1 and my late Taiwann over AD1862 (by few margin).
I totally agree about what you said about the TDA1541 layout needs. Also true for AD1862 if one is using fast modern operationnal amplifiers, but easier if classic I/V stage like tubes, current based OPAs or discrete... or low slew rates OPAs. The mess is more than you have 2 mono dac chips... so great care about the digital front end and GND management.
In the other side, on the long TDA1541A building thread we are going to make a board with the lead of Thorsten Loesch (AMR CD77, Ifi, etc) wit new attenuators, better layout, better PS shematic, all related to each others and the recent discoverings plus experience of few experienced people in their home labs.
Imo the culprit here is not the chip but the board or its power supply design. My actual Audial TDA1541A is still way better than my ad1862A DACS, not by a big margin but 2 or 3 steps above. We have good expectations for the core TDA1541A board to come...
The assembled D3 can be handy for the people not wanting smd soldering (Vunce has great soldering skills).
The late Taiwans are totally almost different chip to me (clearer, thiner but snappier... strange to describe)

Thanks for the heads up Iggy! I haven’t been following this development, is there a dedicated thread? My head spins looking through the “big” TDA thread and I just move away.
So, your poking me to give TDA another try…..I did keep a pair of DAC chips, Hehe 😉.

Try to grab a Taiwann made >1995 . I still do like as second best chip the AD1862. But the TDA is not really a R2R, more an hybrid strange animal. It's like a Rega P3 and a more complicate one with adamantium plateau and virgin string belt, both are good, one is sounding more analog, diminishing return (why we are here btw)
Ah, you look at the last 10 pages. You learn a lot about tubes and bjt I/V with Zoran and Thorsten Loesch; good and sympathetic guys, there are others who input, long known :Alexandre, etc... There are shematics of John as I know you like to make pcb too. (Well here I spent 300 hours on the littlecore DAC that going to be tested & measured to see if it worthss the hassle I spent... step by step is the new black.
Have a read to AMR CD77 review before maybe...
