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).
