I don't care about measurements. For me the actual sound is the most important criterion to determine if I want (or prefer) some audio device. I had opportunity to test my Lyngdorf amp before purchase and no ”bad“ measurement would not changed my opinion, back then or now. Note that Peter Lyngdorf himself said that perfect measurement is not equal to perfect sound (cant find that video right now, but it was about RP).
I like the analogy that an ideal amp is a "wire with gain", requiring no 20kHz AUX-0025 LP-filter (or even the 40kHz AUX-0040 filter Amir uses) to prevent out of band (noise shaping + switching) noise from being included in THD+N calculations... Like in the old days, when my Yamaha amp could reproduce DC-100kHz without an increase in noise above 20kHz, inaudible or not. On the positive side, with compatible piezo-electric tweeters, the ultrasonic noise of class-D can double as a pretty efficient mouse repellant (or bat repellant, depending on the model).See Review and Measurements of Lyngdorf TDAI-3400 Amp & EQ (Part 1) for the rebuttal
Did you try it with rca connection.I had the Denafrips Terminator (and have a Lyngdorf 3400). I ended up selling it. It was superior to optical input but not that different to sources connected by AES. Because the 3400 is a digital amplifier, it effectively reconverts the analog output from the Denafrips DAC to digital, amplifies it and then does its own d/a conversion. I don't think this can be bypassed.
Some here have reported significant improvements with other 'high end' DACs, so I guess your mileage may vary.
My advice is to try before you buy, if possible of course. Opinions about this will go all over te place, especially on a Lyngdorf thread with the majority of the group saying that 'how could introducing extra A/D conversions lead to improvement on an all digital architecture?'. They live in the bubble that all TDAI's - as a DAC - are at least as good or better compared to high-end DAC's.I am planning to buy Denafrips Ares 2 R2R dac to go along with my Lyngdorf TDAI 2170. Will there be any noticeable improvement in the sound quality or the dac in the Lyngdorf is better. I have seeing lot of good reviews about the Denafrips Ares 2 dac. Also I have sent my oppo 203 to oppomod to upgrade the femto clock as well as some upgrades in the dac boards.
But do you not also live in a bubble laying your claim, or do you have evidence to support otherwise? I've no interest in DAC's but from what I read from all these people in a bubble, it's seems to verge on cable mysticism. Logically I could get behind it more if the products sound reproduction wasn't very good in the first place.They live in the bubble that all TDAI's - as a DAC - are at least as good or better compared to high-end DAC's.
Don't count me in that bubble, then – my question would be, "how would a signal be improved if it is DA converted, then AD converted and then DA converted again, instead of being DA converted once?" (assuming that TDAI -> speakers is a DA conversion).They live in the bubble that all TDAI's - as a DAC - are at least as good or better compared to high-end DAC's.
My take on this: key in converting digital files is the reconstruction of the analogue signal and keeping jitter extremely low. Very good DAC's do this job very well and will also have an excellent analogue output stage. In Chord DAC's for instance, reconstruction is done by a FPGA with up to a million taps (when using their up-scaler).Don't count me in that bubble, then – my question would be, "how would a signal be improved if it is DA converted, then AD converted and then DA converted again, instead of being DA converted once?"

I don't have a fish in this pond/pill in this pudding/crumpet in this tea (or whatever English people say), as the weak link in my own chain is the speakers. I won't be adding a DAC for a good while if ever. I just don't understand how the above would be any better than just converting once. I'd have thought that the TDAI, being the last link in the chain, would mess up whatever benefits the external DAC would bring.
I won't deny that there is measurable evidence that external DACs can be quieter than the TDAIs's, but I just don't get how that would translate except if you used the TDAI as the pre, stuck a DAC on after it and then sent the DAC'ed signal to a good power amp with analogue in.
