Perreaux 750 MonoBlocks on the way for Summits

[psychoacoustic]

Kind of like Christmas in September! ?

I have always enjoyed the Perreaux line up and these amps will be combined with the Summits.

This should be interesting.....

What is the Ω for Summits ??

Impressive specs!!

Are they Class A, or Class A/B (e.g. how "hot" do they run?)

 

[psychoacoustic]

Hybrid Class-A/AB & the power supply filter capacitors, total 60,000uF

Details pasted below but we shall see if the pedigree = performance when connected to the Summits.


I am hoping to have them in hand next week {darn holiday delay}

The bi-polar transistors used in the 750 operate in Class-A.
This avoids the crossover notch distortion and the resulting odd-order harmonics present, to some degree, in all other classes of operation. The devices used in the 750 output stage are MOSFETs, which with high quiescent current circuitry, are run in the equivalent of Class-A to 10 watts. Beyond this point the output class is technically Class-AB (hence the hybrid nomenclature), but with a major difference. The combination of MOSFET characteristics and their application in this circuitry, result in crossover distortion so minimal that it is virtually non-existent.

What is the Ω for Summits ??

Nominal 4 ohms, to the best of my knowledge I believe they drop just under an ohm @ the top end (20k hz)
