Flux Lab Acoustics MENTOR Review – Power Overwhelming! https://soundnews.net/reviews/amplifiers/headphone-amps/flux-lab-acoustics-mentor-review-power-overwhelming/

Some reviews of the Xduoo TA-20 Plus, they are often very positive with tests on several tube rolling

I ordered an XLR cable of length personalized for my Sundara. After 2 weeks the cable arrived in France. Solidly constructed, it provides softness and a slightly wider soundstage. Very satisfied with my purchase

New SDA-6 Pro2 confirmed at Magna Hifi https://magnahifi.com/singxer-sda-6-pro2-balanced-akm-dac/

Singxer SDA-6 PRO2 The second version of the SDA-6 PRO, is a high-fidelity balanced DAC. It features numerous improvements over its initial version, and integrates high-end components selected for their audio performance: two AKM AK4499EX DAC chips, AK4191 digital filter, AK4118 SPDIF interface...

xDuoo TA-20 Plus combines Tubes and Class-A with success

I have the impression that there is a third chip on the A8, "AK7738/9(AVQ)" ? for the DSP

Singxer SA-1 Review (Balanced Headphone Amp) : https://www.audiosciencereview.com/forum/index.php?threads/singxer-sa-1-review-balanced-headphone-amp.23365/

:) Can you tell us a little more about Soundstage & Depth as well as bass and treble? Thank's :ok_hand:

I think you can find some interesting comparative information on this link https://soundnews.net/sources/dacs/gustard-x16-dac-review/ friendly

and by using the equalizer of the RME you do not get an improvement ?

Thank you for your comment, with which Dac and which headphones are you testing the SA-1 ?

Great ! looking forward to reading your comments after a few days of use

A few months ago, I ordered the Topping D90 and the Gustard A-18, contacted the after-sales service and returned the Gustard within 15 days without any problem. Feel free to contact them

I bought several products from Audiophonics (Hifiman headphone, Topping D90 ...) and I never had any problems. The point is that you can order the SA-1 and the Burson Soloist and return the one you like the least
