Audio Research LS25 vs Pass X-1

I compared the LS25 MKII to the BAT VK-30SE and the Pass X-1. The BAT was not as dynamic as the LS25 MKII so right away it was eliminated from the audition (I owned the BAT at the time). The LS25 does not have a tube sound and the X-1 had a more laid back sound that seemed a little more refined. It also had better bass extension. I am going from long term memory here as it was a year or so ago.

Happy Listening.

I had an ARC LS25 that I replaced with a Pass X1. The Pass had better dynamics and was just better all around -- more refined. Associated equipment: Pass X350, Levinson 37/360S (later an Electrocompaniet EMC1) and Dunlavy SC-IV/A's. The LS25MKII might give the Pass a better run for the money. Really, though, I don't think you could go wrong with either preamp.

check out audio video logic- they have the pass with the older power supply box(same inside) but identicle to the current version otherwise at about half off retail- can't beat that.
