Is there ever going to be a US distributor or at least reseller for these?
Are they available for "Han Solo-ing"?
@The Life , sure. Just like any other reasonably sized and reasonably priced product available in Moscow and for some reason unavailable outside of Russia.
(the only exception I can think of is Kennerton Odin).
TL;DR: Don't buy this amp
I've had the ZDM for the better part of this year now and until today I haven't really done any critical listening. That's how bad it is.
All listening was done with my modded HD800:
-some hum and some noise, but not too bad overall. Pot has decent feel to it. Top of the amp gets very hot.
-immediately apparent veil - this is very obvious. Makes HD800 sound like HD650; Very dead sounding
-also warm tonally, but not that warm
-this buries microdynamics and microdetail
-macrodynamics are also pretty bad, but not as terrible as the micro stuff
-lacks heft, bass sounds blurry, subbass is rolled off
-soundstage is nebulous, images sort of blur together lacking defintion
-soundstage is also surprisingly small
-treble is actually pretty hard for some reason despite the warmth
vs my Vali 1 that has been collecting dust:
-hiss, the noise floor on the vali is really pretty bad
-channel imbalance on the small pot is horrible at volumes I actually listen at - everything is shifted to the left
-immediately more open, clearer, more resolving
-vali actually has more bass impact hahaha, but doesn't seem to go as low; bass sucks on both
-soundstage is more upfront with more depth and more precise imaging; more layered
-the ZDM smears upstream differences way more than the vali. I had the vali hooked up to a shitty SPC cable and I couldn't stand it with the vali. The ZDM absorbed the sharpness as if cables made almost no difference - still I didn't like the SPC cable.
-this also made it harder to tell the difference between 500kbit/s lossy and lossless.
-treble delineation on the ZDM is way worse - makes cymbals sound like samples
-still, treble on the vali was much worse than I remembered; timbre is off
The ZDM is weird. It sounds muffled without sounding that warm tonally. Hmmm. The Vali (1st gen) or the Leckerton UHA-6s mk.II are clearly superior amps.
I didn't open the spare tube package. It seemed like a lost cause to me.
