Cheapest PCM1704U-K DAC alternatives?

Thank you Abraxalito,

If you have time, could you give me some comparison notes on the HiFi E.T. MA9 versus the Lite DAC-60?

I'll be using either one via USB.

I've seen negative reviews and measurements of Audio-gd's discrete designs so a little skeptical there.
 
I followed your supplied link to the MA9 and I have to say my heart wasn't warmed by what they are saying there. Putting an OPA627 after a 1704, whilst not the worst choice one could make, is far from the best. Also I haven't had wonderful experience with the LME family despite stellar performance on paper. The mention of THD in their marketing does not bode well that this is a design optimized for SQ. If THD were the aim then a PCM1792 surely delivers better than a PCM1704 does it not?
 
Yes, they're using PCM1794 in one of their cheaper models. They prefer the sound of PCM1704.

If not 627 or the LME family, then which op-amps do you like?

The amp board is user replaceable, it seems you can opt for a board using AD797 and different capacitors if you like, plus they send you a VIP card, and give you a real wooden chest.

I have tried non-oversampling in the past but was ridiculed for the TDA chips, it didn't sound very good either, amusical, so I'm looking for PCM chips.

The MA9 is expensive, and the Lite DAC has lots of cheap looking capacitors and cheap tubes so idk. I guess you need to spend $2000 for NOS sound and soon all the NOS chips will be discontinued anyway... maybe should just get the iBasso ES9018...

I don't much care for PCM179X when put up against a lowly TDA1543. Multibit every time for me. Which is why its odd that your featured DAC's designers make a song and dance about vanishingly low THD. - as if they can't really decide what to trust - their ears or the numbers.

I've had excellent results with AD830 and AD8129 but I dunno if you'd consider those opamps. I used them with passive I/V. Also AD603 and AD605 work well if you want an integrated volume control. Georgehifi swears by AD844 (which shares the same designer as the first part I mentioned) and who am I to argue? 😀 LT6552 I have lined up to try at some point.

If you insist on opamp I/V I reckon the LM6172 is hard to beat. Probably AD811 is good too but I've not actually listened to that despite having a few in my parts box.

I'd steer even further away from AD797 in I/V duty than I would OPA627. No amount of boutique capacitors could rescue that....😛

You mean that others ridiculing chips actually puts you off? Me I'd wanna try the ridiculed stuff first 😀 I find TDA1387 extremely satisfying. Non-OS is my favourite but now I insist on doing it with a passive filter after passive I/V.

If you want something really cheap then go for a Lite DAC-AH. It uses TDA1543 but you can swap those out for TDA1387s on adapters and the PCB is durable so withstands fairly heavy modding. I've done three or four with different variations of DACs, including TDA1545As (which don't need adapters but do need the CS8414 output format tweaking). Going this route (assuming you don't actually need 24bits) you'd still have change out of $200.
