that reply is mine isn't it...
I use a Darkvoice THA332 - until I tried that I though hd595 would not benefit from amplification. Now I know that a tube amp of such class will provide what hd595 needs. I do not have experience with high end SS amps, but as I mentioned few other users use higher end tube amps than myself with hd595. I have no experience with cheaper tube amps than my THA332, my amplifier experience is summarized by Porta Corda, Bithead, EMU 1616's integrated amplifer and Echo Indigo is integrated amplifier. (EMU 1616 solidstate amplifier was also quite impressive with hd595 but it was still on the weaker side of bass).
Darkvoice 332 - costs $400 where I ordered (ebay retail seller), with $80 shipping to the united states. In a similar manner you can buy a Darkvoice 336i for $140 less although I am not familiar with anyone using that with hd595. There is also Little Dot 2++, but I have heard lots of complaints about heat issues of that amp.
There is also Xiangsheng 708B which one head-fier has made a whole thread about modding of. Apparently it is a well engineered amp, but the cheap parts (i.e. explanation of its low cost) leave wishing for better, so hence that is what the user did. ( I do not recall his name but I could always find the thread). It can be purchased for $230.
Singlepower Amplifiers start at 1 grand, and generally signify the top range of tube amplifiers, there are various moddles none of which I heard anything bad about. Singlepower is also nice enough to have its own neat website where you can do you homework =].
This is just a gist of whats available. I really value what 332 did with hd595, and am about to start putting in the new tubes that just arrived =].

One reply said that tube amps are good with the HD595s. I do not know much about headphone amps. How long do the tubes last in tube amps? Are they expensive to change? |
In guitar amplifiers tubes are changed every 3 years or so...guitar amps ABUSE tubes (deliberate overdrive to cause distorted tones). With a headphone amplifier you can expect much better lifetime, and in the end replacement is not much of a worry. I just received two tubes that I paid total of 7 dollars for >.< Very little on comparison how much I spent on this hobby so far.
