Again the topic of weight of amps

I built my amplifier system with a separate power supply and separate monoblock final stages with big radio station transmitting tubes and a separate SET with its own separate power supply and, of course a separate preamplifier. If I had built it into one cabinet I could never manage the weight of it all even with my years of amateur bodybuilding. In addition, if something needs to be repaired or I figure out an improvement in the design, it is much easier to take out one chassis and fix it.

When you're in a small city apartment you are sometimes moving things around and cleaning(dust dust dust) you've got this humungous thing just sitting there. No matter how splendid it sounds it's just plain awkward. I remember when somebody asked generally what most one wanted for their system and somebody replied 'a bigger room.'

I have mono amps that weigh a ton.  If space is the issue, new class D like Bel Canto Ref 600m with a good tube buffer will give you excellent results.

I bought an EAR 890 amp in 2006 and used it with an EAR 864 for a two years.  It sounded forward and bright on my Legacy Focus speakers.  With a custom high end pre-amp the 890 was rather thin sounding.  I replaced the pre-amp as well.  I moved the 890 to my Legacy Signature IIIs.  This was a great match.  The probable reason-the Class A 890 doesn't control 6 - 12" woofers very well but has no problem with a 1 ohm higher bass rated speaker with 6 - 10" woofers.  Matching the amp to the speakers is critical for most tube amps.  

My future may include an RM-200 MK11 or a VAC 200IQ.  Depends on my future speaker (Vimberg Tonda, Von Schwiekert VR-55, Lumenwhite Kyara).

I sold my wife on the Gryphon Colosseum stereo amp based on the fact that it took up less floor space than the previous amp because the Gryphon is tall and not wide. It is a slim 175lb amp, lol. I don't know why more manufacturers don't build taller amps.
