A speaker in the 83-84 db range, is certainly going to tax any amplifier, if truthful dynamics is expected. I agree as well, the music, listening room / listener distance, volume levels, etc, all play a big part. My speakers play with any amplifier made ( modified / tweaked Lascalas ), and they do everything I find most important, with my music and in my room. That is a wonderful thing. I say stay away from very inefficient speakers.
BEL 1001 MK5 driving Joseph Audio Pulsars
I own the BEL amp and considering the purchase of a used pair of the Plusars.
My concern is the Pulsars 83.5 dB sensitivity as measured in Stereophile. They do have a benign impedance curve, not dipping below 6 ohms. This to me means a speaker that thirsts after watts as opposed to current.
The BEL is rated at 50wpc into 8ohm and doubles down into 4 and 2 ohm loads, likely due to a very conservative 8 ohm rating. Easily drives my Esoteric MG10s (87dB sensitive, 6ohm nominal impedance) to very loud levels.
My room size is `12.5 by 14.5 x 8.5 feet. An asset for speakers of low sensitivity.
I am looking for thoughts regarding the BEL's ability to drive the Pulsars in a modest size room.
