I have heard that the 650s and the 600s sound alike. For my 600s I have tried several different headphone amps and I think tube amps sound the best. I am using a Bottlehead Crack and and Antique Sound Lab. I don't know what is on the market these days but recommend you go for a tubed headphone amp.
DAC/Headphone Amp For Sennheiser 650's
Folks:
I could use some input here. A good friend who is also a musician has bought a pair of Sennheiser 650's and would like a DAC/Headphone amp to partner with. He likes a very warm and musical sound--not a detail freak but rather likes instruments and voices to sound very natural. Budget is under $1K new but would like to pick something up for $500 on the used market if possible.
Thanks!
