I just finished reading through this thread for I think the second time. I am only more confused now. My DAC is a Reference 7. I need to read some more about it, but I have the impression it is not very musical. Due to that I am leaning towards a tube amp, but haven't ruled out SS. I plan to build a serious STAX rig, and don't want to spend all my money on this setup. I can't see the LCD-2 being my only pair of ortho/dynamic I ever own, so I want an all around good amp, so I can try and avoid buying another in the future.
That rules out the Decware. If I could guarantee myself the LCD-2 would be my only non STAX headphone, I would buy it. I can spend up to $3000, but I would like to keep it in the $1,000-$2,000 range. I was considering the RSA Apache, but think I will cut that out, just because I don't think I want to spend that much. I don't want to deal with a builder for a Beta 22, so that is out. For SS I am thinking Phoenix, or GS-X. The GS-X has gone up in price from what I read it used to be, and almost no one owns one, which I feel like says something.
That leaves me with The P/V, WA6SE, and WA22 for tubes. I haven't read much about how well the P/V work with other cans, so I would have to do some research on that before buying it. If I spend $3,000+ on this amp, I will probably wonder why I did not just by a BHSE, which I will eventually buy anyway. I hate options.
