Here's a few PMC pics - with AVM hardware. Strange looking port on the PMC, but they did sound good. I think PMC make decent speakers in general.

The strange looking port is a wave guide, designed to provide smoother airflow and thus reduce port noise considerably

A posh alternative to drinking straws.

A posh alternative to drinking straws.

That thought crossed my mind too.
You have to admit that the PMC flow port looks a lot nicer than drinking straws would have done.

They were great, thanks for taking the time to post them.

So who had the best sound going on? And no crap about 'it's difficult to say'.

I bet it was them with the Pioneer speakers. It was, wasn't it?

Music First Audio's room, with a MFA passive pre, a Quad 405 power amp, and a pair of Chartwell speakers. The source was a Nagra reel-to-reel tape recorder, but it was (only) a recording from Apple iTunes, not a master tape.

Runner-up was the Harbeth HL5+ 40th Anniversary speakers, powered by a Hegel integrated amp with a laptop as source.

I certainly do - the whole of the M Series

I suppose it is in a way. The owner's son used to work in Formula 1, and the idea was taken from certain aerodynamics findings. It is basically controlling the air leaving the transmission line outlet. Slightly differently, Spendor used a similar idea for the D7 model (if I recall correctly) when they introduced it.

Maybe it's one of the Chinese knockoff 405s. They sound better than the real ones, and look identical from the front.

Is that a generally held opinion or is it your own. I've heard the exact opposite opinion.

It's my own. I've put them side by side with friends present and they all agreed. 405s aren't that common here, but the Chinese models sounded better to my ears compared to a stock 405 with no upgrades other than a re-cap.

I've never bought one of the Chinese ones that had a power supply pre-installed, and always built one myself. I have tried the same power supply in both models and the Chinese ones always win in my opinion.

There are different boards that you can get from China as well. I have always used the ones with the MJ15024 TO-3 transistors.

Is that a generally held opinion or is it your own. .

It could be both. But then it would be opinion as to what qualifies as a 'generally held' opinion.

Sorry, as you were.
