I don’t know the sound of the STX(1), I talking about the STX(2), and it’s only my oponion. 🙂

I have tried the Burson opamps, but these are colored the sound. Without opamps is the sound of STXII more natural. I think the STXII is so good soundcard that you don’t need any modification.

Hi, I had both soundcard’s (same time) im my audio pc but no question, STXII is definitely better. I have changed the opamp as well in my STXII (Burson. Vivid, Classic tested), but the original opamp is the best. You need a good poweramp after STXII and it can be a final solution.

The best opamp is the original one. I tried Burson vivid, classic but the original is the best for me.

I think every sound system is different. I always invite my wife to test of the new devices, cables, opamps, etc. to avoid the subjective opinion/feeling (if it was expensive --> has to be good :relaxed:). We had a same opinion in case of Burson (Classic and Vivid). The Vivid was a little bit...

My STXII is in a Audio PC, so 7pcs linear low noise power supply, clock generators on the main boards, etc... I use the RCA output of the STXII (I think it is the best option), so the signal goes to my power amp (NAD M25), front speakers Elac 249.3. The Burson color the sound, and will be not so...

The original, Muses 8820, 8920.

I have tested the dual V6 Burson opamp’s (Classic, Vivid) but sold these because the original was better. I haven’t got any noise problem with opamp’s.

I do not have 7.1 movie card for STXII.

If you mean the surround=soundstage, than it is a big advantage of STX II compare to my previous system (in case of stereo music). If you mean surround=7.1 card to STXII than I don’t know because I use a Yamaha CX A5100 processor for movie (I have an Atmos setup). I use microphone to measure...

I use my NX4 with my IPad, but works with my Iphone as well. The sound is definitely better with NX4.

I don’t know because I have sold my NU Audio card after 2 weeks. I’m very happy with my STXII. 🙂

Yes, I use the STX II in my hifi system. I don’t know how good for gaming, because I have never tested.

I have been waiting for a same cable....I have ordered it from China 1,5 months ago...and haven’t arrived yet. I have got the NX4DSD very quickly but can not use it with out cable...😔

Dear All, I plan to buy a Topping NX4 dac/amp. I would like to us it between my Ipad and AR-H1 headphone. I listen Tidal (Hifi) on my Ipad. Question: with the NX4 will be definitely better the sound (If I us the NX4 dac as well)? So worth it to buy? Thank you!

I don’t want to look impatient but have you compared already the STXII to AE-9? :-)

Yes, if it is a standard version.

STX needs 5V and 12V also, so I think this is your problem.

I use the RCA outs, it is the way to get the best sound quality. Check the setup of the sound card and the music player.

Ok, I got it. I’m waiting for full review. My favorite is the STXII, I’m looking for a competitor. :) Nu Audio sound card is not a real competitor of my STX II. I have bought Burson Vivid and Classic dual opamp also (for my STXII) but was not better than the original opamps.

Thank you for your comparing. I have STXII and NU Audio sound card in my Audio Pc and the STXII sound is definitely better. Bigger soundstage, open, airy, clear sound, the music alive, etc. If I good understand the sound of the STX II is better then the Soundblaster ae-9?

???

I'm not only think, I know it, because I have heard it... :) I was skepical also, when I heard about it first time, I said: nice fairy tale... After the tests I didn't believe in my ears firs time, second time.....but this is. I always involve my wife in the tests (to avoid bias), and she had a...

Yes, of course. In my Audio PC was a special USB card (with linear power supply, and with clock generator). After the Audio PC I had an Audiobyte Hydra Z USB Bridge with the original power supply (Hydra ZPM). After that a Hegel HD12 Dac + Hegel P20 preamp.
