My sincere thanks to everyone who has taken your time to respond. Amazing kindness!
To clarify, the speakers are 6ohms impedance (per the rear,) 88dB (from a website,) and power handling of 30-200 watts (same website.) They are currently driven by a 1990's Bob Carver, SS, 60wpc, integrated amplifier (CM-1065) with no issues. Interestingly, it seems, the preamp and the amp components are connected from the outside rear, enabling one to disconnect them and connect an external preamp to the amp component. I haven't tried this since I don't have any interconnects yet and I am looking for a total tube experience.
I would consider an integrated amp if I'll have the option to connect my preamp and I would consider monoblocks if they are designed depth-wise and not width-wise due to cramped quarters.
Any input with regards to Bob Carver's Crimson 275? I can pick one up for around $2k.
Regards,
Ken
