Suggest you put your name down here, Nigel.

I have now had the loan BMU for a while and been able to evaluate it carefully with a wide variety of music. My overall conclusion is that it is a simple, well-designed product which gives a significant, value for money improvement.

The BMU is heavy, and feels and looks like a quality product. It was completely silent when in use here.

I tried it with both cds and streamed flac and hi-res files. The changes it produced were clear but subtle rather than dramatic, and slightly hard to describe. The easiest thing to say it that is seemed to clear out the overall sound such that each instrument/voice could be identified/heard more precisely. It also upped the volume a bit, and added to the presence of the sound. As others have said, it especially seems to enhance the sound of drums and cymbals and bass guitar. The dirty bass on Peter Gabriel's "Lovetown" for example is cleaned up and grabs you more than ever when the BMU is in place.

To be truthful, I do not feel I experienced the "night and day" improvements that some of the other reviews has described. This could be because I am lucky to have fairly clean mains where I live, and because the Bryston pre and power amps I use are known for their superior electronics. The BMU is, however, a clear step-up and did produce a much better resolution and improved dynamics with every track I played. One of the best instances of this is Paul Weller's "Wild Wood" - a track that is quite sparse and slowly builds to a strong end.

Overall, I like what the BMU does and will almost certainly get one. The NVA Loan Scheme has enabled me to test it properly and I am very grateful for that. (Special thanks to DSJR for all his help and patience!) It has also made me keen to try the TIS which has been similarly well-reviewed via the Loan Scheme. It will be interesting to see if the TIS makes an equally impressive improvement.

I'd agree with that - the BMU or a regenerator make a fundamental jump in system musicality, the TIS is for well sorted systems that need and are capable of extra transparency and insight.

Is that switching on just the system, Chris, or the BMU too?

The loan BMU is with me and suffered a bit in the transit here - no fault of the previous user, who packed it well for transit. It meant I was able to look inside and confirm no damage apart from a weak clip where the socket had popped open originally (what the feck mains plugs were so tight as to be so difficult to remove?) It 'sounds' the same as mine, so early next week, it should be available for loan again.
