@yyzsantabarbara I was hoping you would contribute. We seem to have similar tastes in audio. I am hesitant to try a different DAC since I just purchased the Bricasti M1S2 a few months ago. I compared it directly to a Chord Dave with M Scaler and a Mola Mola Tambaqui (both in my system) and the Bricasti was the clear winner. Even used it was a bit expensive so I want to hold onto it and enjoy the music. I like the various filter options it provides to match with recording productions.
@audphile1 thanks for the recommendation. I have tried the M1S2 without a preamp in line, but the sound became muddled at higher volume. The LA4 does a better job with the M1S2 than the DAC does by itself. I am holding out hope that Pass Labs will release a dual monoblock version of the XA25. I will definitely upgrade the power amp for them!
@zlone thanks for sharing your experience. I really wish I had found a used XP22 to try in my system. Maybe I will find one in the next few weeks to compare with the LTA and Benchmark. The added benefit of a Pass Labs preamp would be the ability to turn the XA 25 on/off with the remote.
@sls883 @bluethinker I have heard nothing but praise for the MicroZOTL Line 2 form several sources. I have a new one on its way with three sets of tubes (standard plus two different upgrades tubes). I will not be purchasing additional tubes for this comparison, but I will try all three sets of the supplied tubes. It should be fun!
Maybe I will keep the LA4 and switch back and forth.
