Huh, interesting. Mind opening it up and taking some pictures?

The voltage selector is located outside the casing where you swiths either to 115V or 230V.

Took a short hearing and playing with gain. Definitely there is a wider soundstage on Top Gain but level db is same to me.

So far I have put in a silver fast blow fuse in it, Will switch to SS3602 or Burson V6 this weekend after some burning time.

Hm, that didn't work. The corresponding email notification contains two "View attachment ..." links, but they don't work, either.
Yup, it doesn't show..even though I uploaded.

Mid way through burning. Remind me of H10 with V5 but with wider soundstage. H20 still on stock opamp though:ksc75smile:

Waiting for your impressions! :gs1000smile:

Undecided to jump on these or the Liquid Platinum.

10 hours into SS3602. From my Ares DAC balance into H20. Decide to take out my HD700 for a spin on it after a hiatus.

First using SE cable on (H) then switch to 4 pin XLR on HD700. Big difference in sonic changes . Well to my ears only :)

Compare to stock opamps. More separation details so far BUT stock opamps sound smoother to my ears....haha.

Ok, I know the excellent opamps of Burson V5i,V5 V6v V6c. I have them in my other DAC and 1 in my power amplifier and Burson Lycan . Will switch them as soon as Andrew reply me whether his opamps need to burn-in :)

Thanks bro for the update!

If I am gonno jump on these, hopping to have some inputs also on what possible upgrades I can throw at it.

Have a nice weekend!

Can those people here already own and have H20. Can you post your volume mark ( O'clock) on your listening level with which type of headphones and it's impedance at which output?

Maybe I'm getting deaf, my 300ohm ZMF planar listening level it at 3-4 o'clock. Same as my Senns HD700.

The only high impedance headphones I've got are AKG K340 and trying them I'm listening at 2 o'clock unbalanced...for reference I listen to audioquest highthawks at 8 o'clock balanced.

You need balanced connection (gain -standard) for any harder to drive HP...Volume @ noon for LCD-2 ,all them 1/4 jacks are for low impedance HP

Yes I'm using 4pin XLR balance exclusively.

Ok thanks, likely change to Burson V6 this weekend and gauge my comfort listening level and compare to SS3602.
