Allnic Audio A-6000 vs Pass XA 30.8


Maybe an unfair A/B ... yet FYI

After a 17 day x 24 hour burn in of the Pass at solid levels running music I had a listen to trusted digital files I've heard for 20 years as my REFs ... hoping there was a SS amp that could rival the Allnic.  The A-6000s are stock internally, running 2 x EML 300 BXLS on each side. Mullard drivers.  Gain between the amps was within 0.5 db of identical.

Allnic was superior in every category:

Low end had more size, more extension, and more transient punch

Low level details were more resolved, more depth, more beautiful overall image

Harmonic differences of digital vs analog tape tracking in these well known reference recordings were masked by the Pass

Lateral size of both was similar

Midrange freq hardness around 1-3k with the Pass

Strong signature on every playback option that was very obvious.  I heard the amp as much as the music

Thanks @steakster I will investigate 

Modest levels in a modest room   94 sensitivity.  The amps are wired straight to the mid range drivers.  Not much power is needed on these speakers w class d amps on the dual 15s @audphile1 .  30W a side is plenty.  

Yeah it’s just out of its league there in your system and it didn’t have the synergy I’m afraid. When I had the XA30.8 my interconnects were also AZ Absolute Copper. It was super smooth. My problem with that combo was fat bottom end and soft treble. That was with Pass XP22 preamp. I moved on to X260.8’amps and Nordost Tyr 2 XLRs and all the issues were resolved. Synergy is key.

thanks @audphile1

partly could have been the AZ Absolute is super smooth in the top end and favors a lower octave so can seem dark and too fat.

Matrix ref II is a more lively curve
