Topping DX7 Pro DAC and Headphone Amp Reviewed

As far as I understood we can use A90/DX7 Pro(not sure) like preamp
as far as I know
DX7 pro and A90 are Preamps, you can't drive a speaker bookshelf unless is a monitor active speaker in that case yes.
the link that you sent me is a normal (passive speaker), so no it won't work, not with Dx7 pro or A90 at least not directly.
for speakers you need like
topping MX 3

in that one you can connect speakears directly. other wise you will have to use other source, like in my case I am using a Denon AVR to power Klipsh speakers
Headphone output of the A90 sounds better - in my ears. The big advantage of the DX7 Pro is that you can control the volume for the headphone and preamp output separately and by remote control. Neither is possible with the A90.
They are Headphone amp , not designed for a passive speakers they won't work.
did you read the review from Amir ?
" If your headphone has an impedance curve that is a) less than 60 ohm and b) is not flat, then its frequency (for better or worse) may change a bit. "
the problem with high impedance is with the headphones with low ohms like ATH-m50x which is 38 (much lower than 60) so the frequency curve will be affected, probably the same with the sure, but no that much.
there is no problem with HIgh impedance headphones like 200 ohms or more.
Checking in as I picked one of these in a search for an all in one unit that my Sabaj D5 sadly wasn't able to fill as it had too much gain for my HD6XXs and subjectively I found its headphone amp to be a tad shrill. While I can't hear any differences between them through my active monitors I find the headphone amp on the Dx7 Pro is much more enjoyable, very clean but no fatigue, can't fault it with high impedance cans anyway. So far looks like a keeper.
Mine will be here tomorrow......Since it is a Silver version, it will sound much more transparent and lifelike with less deception and lower upper level harmonics.......
Always wanted to play with the sync/async mode on ESS DACs and fortunately there is a setting to put the DAC into sync mode on the DX7 Pro. IMO it removes some of that hint of processed sound flavor that some attribute with ESS DACs, I don't really know what it means perhaps it is due to it performing worse in the sync mode, but the sync mode seems to be a bit easier to listen to and it sounds a tad less lean. Not a controlled test, so take it with a grain of salt.

Well, this DX7 Pro will be returned. I bought it to use as a preamp and a high quality Bluetooth receiver. It does not sound good at all! I'm comparing it to a Yamaha CX800u, Schiit Sega and DOUK P1.......All sound WAY better than the Topping. The DX7 sounds "brittle".....The highs are terrible through the Magnapans and the Klipsch RP600m speakers. On some high notes the Maggies actually ring! The bass is lacking and what bass there is sounds "Fluffy". Uncontrolled and not tight like the other preamps. I tried it through the Dynaco clone tube VTA-ST120 and a refreshed Yamaha M45 in both class A and AB.....Same results with both. My source is exclusively a Bluesound Node2i. Unfortunately the DX7 does not have analog inputs so I can't compare the DX7 DAC with the Bluesound internal DAC. The BlueTooth is even worse. The bluetooth on the DOUK P1 is much more listenable. Hard to believe how good that $109 DOUK P1 tube preamp sounds. Maybe I got a good DOUK and a bad DX7.......Who knows.
I've tried everything possible to get this $650 preamp to sound like a $109 DOUK P1......It's just not there. Measures great, sounds bad....The Klipsch RP600M sound amazing in my room with all the other equipment mentioned.
^^^ More or less I think. Conceptually it uses the incoming signal to clock the DAC chip and disables ASRC and jitter correction (?) at the same time. Only Topping engineers can definitely say what actually happens. The clock is either the clock recovered from SPDIF or the USB async input clock. I'd say that running the DAC in sync (no ASRC) is the preferable mode of operation if jitter can be kept under control.
We will see, I have sent the question to Topping support. In my case, I want to use 3 of these DACs on SPDIF (AES/EBU from a RME HDSPe AES sound card) for multichannel. That's why, I want the more direct clocking way. I'm ok to do some compromise on jitter as long as there is no audible drift in audio. Actually, I have such a config with 3x Musical Fidelity DACs with no audible issue. World clocked items are too expensive for now.
