Ok, so Patu came to my place with slightly less than 20kg in gear. (No, not that kind of gear...)
He brought his hefty Storm Digital D02 DAC and his RudiStor RP5.1 amp, along with a flight case full of wooden glory, the Audio-Technica W5000.

My contribution was the following: Zhaolu 1.3 DAC (fully modded), Single Power MPX3 with SLAM adapters and AKG K1000 and Grado RS-2 headphones.

So we had the perfect opportunity to compare some fine apples to some fine oranges:

1. Zhaolu Vs. Storm Digital
2. RudiStor Vs. Single Power
3. W5k Vs. K1k (Vs. RS-2)

The results? In a nutshell: a few eargasms but no transcendental comparative findings.

1. The two DACs were surprisingly similar. In my opinion, the Zhaolu had an ever so slight lead regarding separation and dynamics, and the Storm Digital was slightly more analog-sounding and smooth. Actually these findings are quite logical, as the Zhaolu is an oversampling DAC and the Storm Digital is a non-oversampling one. What was really surprising was that the differences were so small. We were able to tell the difference after a while of blind A/B:ing, but it was not easy.

2. A hybrid amp versus a tube amp. Again, the differences seemed to be subtle. Well, actually the differences were subtle when comparing the MPX3 fitted with three 6SN7s to the RP5.1, but when we SLAM-adapted the Single Power, the differences were more obvious. The RudiStor is a steady performer. Very neutral, very smooth, a fine sounding amp. The MPX3 stock was pretty much the same as the RP5.1. In our meet conditions we were unable to tell any significant differences between these two. But the MPX3-SLAM is a different story. The dynamics increase and the SLAM appears, and that smooth, refined experience is replaced by something more brute and visceral.

3. The most apples and oranges of them all: W5000 Vs. K1000. I just love both of these and would love to own them both. The W5000 are smooth and beautiful, the most comfortable pair of cans I've ever worn. And the sound, ahh... What a voluptuos, sweet, elegant, fun and musical experience that was. Very fine indeed. The K1000s are the diametral opposite regarding looks and comfort. You look like Mickey Mouse on acid wearing these things, and while they are quite comfortable when finally positioned correctly, there is no forgetting you've got two cheese graters protruding 10 cm:s from the sides of your head. The K1000s are fast and detailed like not many other dynamic cans. The soundstage is more speaker-like than headphone-like. Actually I don't think it really helps anyone if we directly compare these two cans. They're just two completely different animals. IMHO, the W5000 is one of the finest experiences ever regarding dynamic headphones, clearly more so than my experiences with the HD-650, the K-701s or the SA-5000s. I wouldn't want to compare them to my Grados, because I love my Grados and don't want anything bad to happen to them....

But the sheer fun of the W5000s is pretty much Grado-like, and this together with the best comfort ever, makes these cans a brilliant product. The K1000s are dynamic earspeakers, and I'm not going to say anything that hasn't been said already about these. I love how the K1000's headstage grabs you, and almost forces you into some ferocius headbanging and airdrumming (listening to some metal, that is...). Maybe Patu wants to comment further on these.

Conclusions: Get yourself a decent DAC (asian budget DACs rule!), a really good amp with some tubes in it, and lots and lots of wonderful headphones to play with, and you'll reach nirvana. Or at least a few dozen eargasms.
Regarding the sampled gear, I would be happy with any combination of the above, but I would really, really, really like to own both the K1000 and the W5000. (Sponsors? Anyone?)

(The expressed above are my impressions. Let's see if Patu chimes in with his...)

What a choice of words.

Actually it's not really "useless", if I intend to use the DAC with a headphone system. Of course it would be easier to hear differences with a speaker setup, but the results would probably be "useless" from a headphone user's point of view.

thx for the review

what version of zhaolu is that? any sorta mods?
The storm digital looks nicer, how much would it cost?

I think I'm more after the zhaolu type of sound tho 0_o

As I have found with the DAC-1, you cannot measure fatigue through such short term comparisons - I found I couldn't listen to the Benchmark for nearly as long as the D02 (around 1-2 hours vs. 6+ hours!)

It seems many subtleties reveal itself over time; I should have gone longer on the Jadis vs. Benchmark comparison, since I dismissed them as being the same through quick A/B switching (every 5 seconds, 10 seconds, etc).

But, it is great that these two chinese DACs are similar through short-term comparison - no inherent faults at quick listen!

Hi, I forgot to ask:

What transport was used, what music was used, and what bitrate?

Thanks!

We used foobar2000 0.9.1, MP3 320kbps and EMU 0404 as transport (and I forgot my test tracks at home

so music wasn't so familiar to me). I don't know about the settings of foobar (was there ASIO or KS or what.. dunno, Comfy can clear this up). Zhaolu was connected with coaxial and D02 with optical at the same time. Interconnects were different and we did our comparison in like 20 minutes. So the circumstances weren quite bad for good comparison.

So as said before, these results aren't very reliable. It was just quick test and nothing more. When we have more time we can do deeper comparison.

Everybody has a different tolerance for fatigue so it's all relative. When you get more training, you can easily hear if the sound would be fatiguiing in a very short amount of time. Not that you are already fatigued but you can judge it will be.

The character of the sound will reveeal itself when you listen to various things connected to it.

There's also burnin

Oh forgot to mention that I got D02 on monday and have used it under 10 hours so there's not really any burn in with D02 yet.

The Sanyo OSCON caps need a lot of burnin in my experience. Sound get better in the next week or two.

Yes, no offence, but different IC's, different types of connections and MP3's used over short period of time doesn't sound like optimal conditions for a comparison by any means.

My point exactly. But I'm sure we'll do proper comparison after D02 has more burn in and in better conditions.
