More likely in parallel to double the power handling. The 3kw unit is twice the width of the 1.5kw unit, which suggest the larger one may be just 2 of the smaller ones in parallel.

Yes, they could well be the case. My own is just one big transformer but I believe the 5000VA unit is two transformers stacked.

For those so concerned, I have now fitted the cable strain relief!

going off topic,mark did you ever find a spare set of defraction rings for the yammys?

Sorry, got distracted, forgot - I’ll have a look (may need reminding). I’m sure I’ve seen something (I’ve got a LOT of ‘stuff’ - unfinished projects, part built projects, prototypes, models etc).

Hmm... plugged the BMU into the system last night and had a brief listen. To be honest, I was a bit underwhelmed and thought the sound may have been a touch more 'vivid' without it. Perhaps I was just feeling jaded and it was too late to do any A/B comparisons - will listen some more over the weekend (the noise floor did seem extremely low).

It seems to be taken for granted that these things make an improvement but when I tried one I was not keen on the change it made to the sound.

In what way exactly Martin?

**Macca** · 29-09-2017, 12:55

Perceived dynamics were reduced, sound was a bit 'sat on', there was a weird echo/reverb effect in the bass. Not huge changes, very small in fact, but they were there.

I persisted with it, but when I took it out of the system the improvement was immediate and obvious.

Hmm... interesting.
