Pros - Very good Head-phone amplifier - very good pre-amp for the largest active Argon speakers
Cons - The irritating 25-35 minutes it takes to warm it up before you can start using it!
This is the "Best Buy" I can think of, if you want a combined headset-amp &/or pre-amp for active speakers. I´ve used it with Argon 7460A with really powerful results! As a Head-set amp. it is MUCH better then f.x. Cambridge Audio DacMagic Plus.... It gives the headsets a wonderful warm sound!
