To anyone reading this and contemplating doing the same with the Bushmaster: DON'T!!!

Just opened my BM for the first time (to replace the Eprom with the update that Stanley kindly sent me - it wasn't reliably 'seeing' my Apple TV after power off of the source, etc) -

WOW is it a beautifully designed and constructed bit of kit or WHAT?

Well done Stan:cool:

Hi Malcolm,

I'm having Source selection issues with my apple tv too.

Let us know how it works please.

Cheers,

Yes, I took a peek inside too. Lovely bit of single PCB design.

Looking at your signature it the blue one ( 2.1mm) to fit your squeeze upgrade PSU.
If you contact where you bought the PSU from in the Netherlands they will send you an an adapter.
I send them out for free to my customers so that people with a PSU from previous Beresford Dacs dont have to spend any more money when they upgrade to the Bushmaster. All part of the service :)

I remember commenting on the very same when I saw the PCB layout of the prototype that Stan put a picture of on the forum quite a way back :)

No idea what thread that's on, but if it's still similar or the same....

:cool: :D

The qualities Nick's PSU has above the others is ultimately it is cleaner sounding, its not as brash as the Stan unit, the hefty one isn't far off Nick's so I am guessing it is a Linear supply, hence the clean audio.

As a consequence of this cleansing of the audio signal you can interpret low level detail slightly better, perhaps its more coherent and better organised if you know what I mean...

Its also less fatiguing as well, I was sat listening to one of my reference CD's (The Art of Noise's Seduction of Claude Debussy) and I was not finding it hard work.

I think the stock Stan unit you get is louder, I would say by about 1dB or so (my Leema amp has 0.2dB volume steps), and I mentioned previously to Nick the low level detail is there with the stock unit, it just gets uncongested with the higher spec PSU.

Ultimately I guess the question would be “would you buy one”? I am unsure on this, don't get me wrong it does make a difference but I wouldn't say it made a £200 difference like the Squeezebox Touch power supply made, its better but its not jaw dropping difference better than the Touch one.

I guess this is a testament as well to Stan's DAC design more than anything, as it must have a good noise rejection front end that cleans up as much as it can before it gets to the audio parts.

Which power supply are you using for your Touch?

Nick's LDA one distributed by Dave:-

Worth the £200 in my opinion...

Thanks for this info Mark, I will contact Wiebren Draaier when I order a BM. He's a nice guy who obviously selects his resellers with great care.
