You listen to them. This is hard with headphone amps so you have to go on what other people say.
Basically people who own or have owned HD595's are typically good references. Other noobies aren't that great of a reference as everything sounds good when you first get into hi-fi audio.
HD595's love tubes, which is why I suggested a LDII amp. the Little Dot amps are cheap, but can compete with other amps 2-3x their price. They aren't the best, but for the money they're hard to beat.
You could also look for a used Millet Hybrid, but they can get spendy. The Millite Max I suggested is better and a little cheaper, but you won't be able to get a used one for some time as there are only a few in existence today. There is a group buy for the boards that ends today and then there will be many more amps around. Like I said, I have 3 boards on the way and plan to build one for myself and then sell the others. It's cheaper to buy parts for multiple amps instead of just enough to build one amp. I'm probably going to go all out on my Millet Max though... boutique caps, custom case. It'll look and sound good
