After having owned a number of headphones and amps, I may be near the end of my search. I have two Decware units....a CSP2+ for high impedance cans and the Taboo II for the low impedance
ones. I changed the cable on my HD700's to a homebrew I made with Canare cable and it sounds wonderful with the CSP2+. So much so that I may sell my Crack and HD650's.
The taboo II with my LCD-2.2's is also excellent. After playing with some rectifiers, I have found a couple that have the sound I was after. I may just sell off my other phones and amps because these are the two I listen to now. The CSP2+ drives the Taboo beautifully...which in turn is moneywith the LCD-2.2's. May look for a cable for the Audeze cans, but that's about it. At least for now
