Like @Alcophone said my unit is not new. I bought it off another head-fier here. I’m not sure of how many hours he had on the unit but it sounds good in the state it’s in.
I believe burn-in makes a difference and as I put more hours on the H20 I hope to hear it sounding better. I don’t expect it to deviate to far from what I’m hearing now. This amp sound neutral to my ears with the stock op-amps. There not one band of the frequency that stands out more than the other with the stock op-amps. With that said I want a little more bottom end and I want the notes to have more weight to them. What I’m hearing from the stock components is not that so far.
I’m with you on system synergy. Matching up gear is huge. But right now I’m just listening to get a grasp on what this amps does best and how changing op-amps will alter it. After all changing op-amps is part of the fun.
That's great. It's just speaking as an interested observer, sure, the effects of different upgrades are of significance, however I want to read first about 'how this amp compares to other amps', rather than 'what effect do different op-amps have'.
To that point, you refer to bass weight (something close to my heart- hence my moniker): do you mean that the H20 lacks this, compared to other amps?
