    1 bit DAC launched by TOPPING

    Well, Burson do that since 2009 with their OPamps, I tried some of them before and like it, but w/o an audio analyzer like the APx555B I don't know if it introduces more snr, thd, sinad, etc, to the sound/music. I tried them when I had my D50, now I'm on "default" E50+L50. More about them...

    1 bit DAC launched by TOPPING

    Some impressions: "I got a chance to listen to the A900/D900 at CanJam and was very impressed. I thoroughly enjoyed listening to the 2 units. The sound was very relaxed, engaging and balanced. Very engrossing listen that drew me into the music. I was told the new units would be released toward...

    1 bit DAC launched by TOPPING

    D900 looks $2k, around the same for A900 (perharps it will be even more). D90 III discrete got my interest: "The D90 III Discrete uses a positive and negative 16-element DAC for each channel, achieving high performance indicators of THD+N<0.00006% and SNR>128dB. Its appearance is similar to the...

    Future DAC/HD AMP upgrade

    I see. I was looking for an 100% balanced stuff, then I think I'll upgrade my headphones first, actually I have my trusty/almost-legendary HD650. Was looking at HD800S, but I don't know if is really worth the price, I know they are made to last, but other than that, I can't believe it will...

    Future DAC/HD AMP upgrade

    I'll post it here, as they are both: a DAC and a H.D. amp. I'm thinking on a future upgrade from E50+L50 to a DX9 or D70+A70 ("pro" ones), or something else. Price difference is $99 or less. Thoughs?

    Topping E50 Review (Balanced DAC)

    Is fine, but because of isolation, and isn't expensive at all, I use a GST25A05-P1J: https://www.meanwell.com/Upload/PDF/GST25A/GST25A-SPEC.PDF Total overkill I know (4A), but can use it to another things if I ever needed.

    Buy USB isolator for E70 Velvet? E50? E30II?

    Short answer: Just use a good power supply like Mean Well, and problem solved. Something like $20 or less. Long one: A DAC where it completely separates the input receiver section from the audio section, be it USB or S/PDIF, since they need to be connected in some way. So there will always be...

    Is there any budget DAC for DSD1024?

    You cannot hear the difference between DSD (1x) and 96kHz @ 24-bit (PCM/WAV). The later is better anyway. So WHY would you want DSD1024 ?!

    Topping E50 Review (Balanced DAC)

    Just use meanwell psu (like I'm using). Is less than $15 shipped, and the quality is good enough (or pro enough).

    Topping E50 Review (Balanced DAC)

    HOW? There is no review on ifi. If sounds "smoother" then is NOT transparent.

    Topping E50 Review (Balanced DAC)

    That's just placebo effect. Your brain is playing tricks to you, because you payed more for it, the brain NEEDS to recognize that money spent as "better quality". E50 is transparent, but I have doubts about the ifi.
