If you're using the T1 exclusively, which is prone to hot treble and has excellent sound-staging capabilities as it is, then maybe the benefits won't be so apparent to you - they might even sound worse to your ears with the acquisition of AP2. Personally, I find that it does improve the T1 but not to the extent that it improved LCD-2 - that was night and day over the Conductor's USB.

It's probably a question of system matching. Don't ask me how a USB interface can have a bright signature but it has been said of the AP2 and my findings tend to confirm that notion.
It is exclusively HD800 these days for any critical listening.

I think the crazy USB interface rolling folk operating within this thread may tell you that the Hydra-X has the better synergy with HD800. I don't know anything about that.

+1
Hydra seems to be better with HD800

Haven't heard the ap2, but my hydra-x seems to play well with HD800. However, because I haven't heard the ap2, i cannot tell which is better with HD800. negura who had them both said that he likes ap2 better with lcd3, and hydra-x with hd800.

It was him I was alluding to. Lol

Now, I am really intrigued and genuinely wondering if any of Hydra-X owners have done proper ABX testing and if in blind test the difference was really that dramatic as in sighted.

 

There is one interesting article on the most challenging task in audio industry - proper evaluation of different equipment.

 

Audio Equipment Testing White Paper

 

I for once didn't know that auditory memory is that short - just 2 seconds and how strongly the bias can influence the results of test.

 

Anyway, my brand new Conductor is officially for sale if anyone interested. As DAC it's just lagging behind Chord DAC64, and the difference is not that small as I hoped. :(

I have always told people that auditory memory is very low. We are visual "animals" and rely very little on ears compared to eyesight. 

 

Here is a little test that is about audio memory too : http://tonometric.com/rhythmdeaf/ (got 96%) :D  (if you cannot make the difference between 2 slightly different rhythms, it will be even harder to notice the difference between identical rhythms with subtle differences in details, airiness, transient response, etc).

 

A good way to exercise your memory is to try to imagine how the sound looks / feels like (as it is easier to remember "images" / feelings ) . For example with hydra-x the sound flows like a clear mountain river, vs stock usb where I didn't get this feeling/image while listening to the same song.

 

Interesting test for this : http://jakemandell.com/amvi/ (got 100%).

 

On my part, I have no doubt that my Hydra is way over usb stock. The difference is quite big for me.

Very interesting. As I said, imaging processing has priority in our brain. If you close your eyes, you hear the right "bah" :))

Flipping between them back and forth right now, both with iUSB Power to minimize noise from PC.

Kind of surprising, is Tenor that bad?

Hmm, shouldn't be THAT bad. My friend Darku compared the USB with a even pricier M2Tech interface and didn't observe differences (see http://soundnews.ro/2012/11/19/burson-conductor-simplicity-squared/)

 

Now I am really interested in his impressions on Conductor with Hydra X.

After more burn in and properly set up test I can't tell any apparent difference between internal USB and Audiophellio2 paired with Pure Power. Hydra X is actually cheaper than AP+PP, is it really that better. Negura didn't seem to be very impressed with it. :confused:

Have you guys done any assisted blind ABX test with Hydra? Did you use the latest Burson drivers and 24-bit Burson Async ASIO output?

I have tested with the latest drivers from burson as well (with async asio output). Still a big difference. I haven't done blind tests, but the difference was to big to recur to that.

Yes, negura liked the ap2 better. What usb cable do you use with ap2? Did you try a coax cable between ap2 and conductor. Negura and Tony considered it is much better with a coax cable than directly into Conductor.

 

What output do you use with ap2?

I am not an easy believer and I'm the first one to doubt what I hear but the Hydra made a clear, undoubtful difference for me.

In a blind ABX test?

Sorry for questioning guys but we all are just human, biased, emotional creatures, and often listen with our eyes and wallet, unfortunately. :(

I remember my early days in this hobby when I was finding difference from aftermarket cables undoubtedly stunning and would fight anyone who question my findings.

 

I can clearly hear the difference between Conductor and Chord DAC64, can hear some marginal difference between iLink and AP on Chord, but on Conductor iLink, AP, and internal USB all sound the same. All testing is done with quality coax cable (Zu Ash) from AP to Conductor or Chord and HD800. Have tried hi res and good redbook recordings like last Nightwish album or Yello "Touch".

 

Would love to hear what Darku thinks about all that as he was the first one who found internal USB implementation at least as good as M2Tech Evo, well respected DDC.

I am the first one to conduct a blind test when needed. I never found differences "from aftermarket cables undoubtedly stunning" and never fought "anyone who would question my findings". The difference is this case is as the DAC was switched.

 

DarKu has bought a Hydra so that says everything :)

This is very interesting. Has anyone besides Negura compared Hydra X to AP?
