Hi,
First post here - very happy owner of a Bryston 4BSST2 and a PowerPac300 driving PMC main and center speakers. The set-up has served me admirably for around a decade, and am contemplating next steps.
I have a question for the group based on what appears to be a trend towards lower impedance loudspeakers over the past decade or so. Within the Bryston range, which amps are best suited to these current-demanding speakers?
Thanks in advance for any thoughts or feedback.
More detailed background to question (for those interested): with speaker sensitivities being measured as 2.83V rather than 1W, it seems speaker manufacturers are driving towards lower and lower impedances to make their speakers 'appear' more efficient. 2.83W is equivalent to 1W at 8 ohms, but is 2 watts at 4 ohms, and so on.... Looking at recent review measurements, it's not uncommon to see speaker impedances <3-4 ohms for much of the frequency range, which when coupled to phase angle, can lead to equivalent peak dissipation resistances of down to 1 ohm. If an amp shows specified powers to 8 ohms and 4 ohms, how does one go about predicting ability to drive impedances below that?
