Yep that's my approach to hi-fi purchases as well!

When will you receive the new one?

Nice one Chris . Enjoy

Please keep us posted when you receive it .

I think you may need to flog 'em both, judging by Martin's opinion of the cable.

Well done Chris. There is no going back to raw mains now!

Hi

Earlier on this thread I posted the following about the BMU:

"I've got the BMU at the moment and I am well chuffed with the results. I've repeatedly switched from mains to BMU to mains to, etc. and the difference is significant. The BMU offers much better SQ. Better in fact than I had expected. By 'better' I mean clarity, depth of soundstage, instrument placement and transparency all get a big boost. And for once this is not 'I've got something new so there must be a difference' situations. The improvements are soooooooooooooo obvious. Drum kits in particular (my favourite instrument) are just a joy to listen to. Great cymbal decay, easy to move around the kit, great cymbal/tom placement, etc. Lovely.

Hats off to NVA! I don't think I can live without their BMU. Total no brainer.

Now,where's the nearest 18 month interest free balance transfer credit card deal..."

Well, I've been without the BMU for nearly a week which has given me time to reflect on my stint with it (plus DSJR has asked me to expand my review).

First off, I really miss it. It's one of the best hifi products ever made. Must be.

I know that there is a picture of the BMU at the start of this thread but it does not do it justice in some ways. Trust me, the BMU looks even better in the flesh. Panel fit is first rate: there's a lovely glossy finish and it's pretty heavy too. Make sure the old goolie strings are in good shape though before you lift this beastie! There must be a monster of a transformer in there which has to be a good thing. There's a nice long chunky mains cable too which was really useful. No obvious way of opening the BMU or signs of any fastners either. The NVA workshop must get through a lot of glue. Probably a great place to work with all that solvent permeating the air...

I had no problem with the location of the plug sockets. I liked them where they were as they prevented the plug cables from getting in the way of each other.

Okay, so the BMU looks and feels like a high end product (at a bargain price) but its real ace card is how it utterly transformed the sound quality of my system. Every aspect of the sound coming from my speakers was improved. In all respects, the SQ was so much better. Not subtly, but significantly better. I'll be honest here. I'm a cycnical ba****d at the best of times, so I was prepared to be totally underwhelmed and dismissive of the BMU as another product destined for 'audiofools'. No chance. The only way you could not instantly detect a difference is if you are deaf.

The BMU makes your hifi sound clean, crystal clear and more dynamic. It's as if a thin obstructing layer of material has been removed from the front of the speakers. Want more?
Soundstage - wider, taller, deeper
Instrument placement - pinpoint and so much space between them
Timing - notes start and stop with such precision. Bass kick drums much tighter (but no deeper)
Detail - it was much easier to unravel complex layers of overdubbing. Not sure what that feint noise is in the mix? The BMU will draw it out. It's not so much a case of extracting things you have never heard before, just making them dead easy to identify.
Vocals - clearer (ahh, so that is what Sting was singing...)
Improved transient response 

My Ayon CD player has a light which tells you when you are not getting power from the mains. It stayed illuminated all the time I was using the BMU. So, no naughty stuff going on there. You really are disconnected from the mains.

If the above sounds like the gushing of a deluded audiofool I can assure you that it's not the case. I cannot recommend the BMU enough.

For the cynics out there (of which I am one), please note I have no connection with NVA. I'm not a shareholder, investor, relative, friend, etc. It's simply the case of drawing attention to an outstanding product which you guys/gals need to get a loan of. Be careful though, as you will almost certainly want, no, need one within minutes of listening to it. It's even a bargain too FFS!

I'm saving up.

Cheers

Steve

Thanks Greg.

Thank you very much chaps for taking the time to type these reviews. Takes a lot of pressure off this end

The NVA BMU is nicely constructed in a fashion similar to NVA's other products. The rather novel difference is that it is fitted with Aldi/Lidl domestic appliance anti vibration feet. On delivery it was very cold so I left it a day to warm to household ambient temperature. On plugging it in and powering up, the mains circuit breaker did not trip and it hummed/buzzed quietly for a few minutes before becoming silent. For the rest of the week it remained powered up and was silent throughout. At no time did I detect any significant heat being generated by the unit. Like Martin, I don't like the modular 13 amp sockets fitted. One in particular would unclip from it's housing when the plug is withdrawn. Whilst it will readily clip back into place, I suggest this needs some attention from NVA.

The four sockets was all I needed to supply my RPi/HiFiBerry + streamer, Beresford Caiman ll, DIY pre amp and power amp so I used it to power the whole system. Music streamed was lossless files in high resolution.

I held several extended listening sessions with it in place not so much because I needed the time to draw a conclusion on if it made a difference, but rather that I enjoyed the difference it made so much compared with standard mains supply that I wanted to listen to as much music as possible.

I found the BMU improve the sound across the full frequency range making the presentation tighter, more controlled, cleaner and as a result, more realistic. In terms of realism, this was very evident when listening to a good (there aren't many of them) quality live recording. I felt I was much closer to listening at the actual gig. More aural information is revealed including micro sound detail assisted by an overall drop in the noise floor.  The immediate impression is a boost to the bass, but the reality is the improved sound resolution happens right across the frequency range. It is the improvement to bass, however, that is immediately striking, yet once I got used to the sound, I identified many areas where I was hearing a much better reproduction. Furthermore, the speed and attack on notes was much sharper and overall, there was an enhancement to the weight and authority of the sound.

What the BMU brought to my system was a considerable surprise as I was expecting only subtle changes but the difference was very evident and undoubtedly enhanced my listening enjoyment and experience. 

With a a degree of reluctance, I handed the BMU in person onto 'alaska' this morning.
