Does dual mono actually play as stereo?

Sorry, I`m not actually sure. I need to be certain! For example the Musical Fidelity A3.5

“Dual mono” means that each channel is completely independent of the other, and shares no components at all, unlike a normal amplifier where at the bare minimum, both channels would at least be fed by the same transformer - each channel is a completely independent amplifier in itself from the start of the input to the output, including its very own transformer. The channels are usually mirror imaged too.

It does play as stereo, but

It does play as stereo, but as David pointed out reflects build.

A3.5 was and still is a very respected amp. With lots of power and high current. Bargain at second hand prices where you can usually find out around £400.

From my limited knowledge

Every amp has one transformer feeding both amplification channels. But when both the channels have their won indipendent transformers, it's called dual mono. Essentially two mono block amps in one single casing

Thank you all. Interesting.

Thank you all. Interesting. Insider9 assures me it is stereo, which is enough for me. Thanks. PS insider9, in our recent correspondence regarding the Musical Fidelity, you suddenly gave up on me?!

+1

Normally described as a stereo integrated or whatever built to a dual-mono design. Forget the mono bit and read two identical and seperate channels of hardware each handling a left or right signal.

I'm so sorry, I did. I must've read it and wasn't able to respond, then it slipped my mind.

The whole point of dual mono is better stereo separation.

Good stuff!

Bored? No, not at all. I've got Esoteric F-05 in for a review so won't be bored for a while.

It might even keep you guys entertained Smile

That's mouth watering impressive looking amp. Is the F-05 the Class AB version?

Indeed. It is class AB. Let me bump that thread with some pictures so you can see it.

Good choice. Going for class A with enclosed heatsinks usually is a big problem for a large integrated.

I'd need 3 people to carry it if it was Class A. It's 32kg plus a bit more for a chunky DAC board as it is. 120Wpc into 8 Ohms and 240 into 4 Ohms from 940VA transformer and massive caps. The box nearly doesn't fit through the door Biggrin

You can make yours pure Class A by turning up the biasing at 1.3A+, but then it won't be 120Wpc. PSU will clip at 30Wpc or less, considering 60% of the power will become heat and make the wooden rack catch on fire.
