After many years of being an audiophile, I decided to purchase a dream amp. I have owned many high end amps in the pass, but got tired od chasing the holy grail. I previously was using a jolida tube intergrated in my bedroom. Even though this was not an expensive amp it had the typical beautiful tube midrange. Eventually I upgraded my speakers and the Jolida just did not have enough juice to drive them to full potential. Enter the pass Lab. This amp is class A to 30watts. I would describe the sound as Mellow and liquid. It has a very pleasing sound and is never harsh sounding. You can listen until you ears just tire out. It grips your speakers and take full control. It does all the things and highend amp it suppose to to. Wide soundstage, 3 dimensional, air around all the instruments and reproduces all the music from your source. I believe the term is detail. Midrange is not tube,but vocals sound real as if in the room. If I had a complaint about this amp it would be it takes a good while, for the amp to get hot and sound its best. The Pass is an amp that does everything right and nothing really wrong. Until it breaks, this is my last amp purchase.
