My journey in the listening chair has been ear opening to say the least. One thing stands out however from the sea of gear...class A designs sound more natural and have greater presence i.e...older Krell, KAV Krell and Evolution Krell (not evo). Tubes can be pleasing but give me just a little to much frequency extreme anomalies and a reduced sense of presence or tension. Mac is one of many solid state/tube manufacturers that make reliable good sounding gear, and that's ok. Mac can be warm, full and reasonably able to convey the essence of the music..it just doesn't give you goose bumps! I believe high end audio hit it's peak in the mid 90's and is being gradually dismantled in favor of ergonomics, current trends and alternative technologies. When I was growing up on vinyl and Bozak speakers, everything sounded amazingly full, dynamic and tonaly correct. My current rig gives me the same feeling on even redbook. Whatever you own, enjoy it and let each find their own yesterday.
