Beresford Bushmaster DAC Reviews

Apologies, I must have done it again and mis-understood you. Are you saying that the Caiman remains constant throughout all this in direct comparison, yet the Bushmaster changes in comparison by the day?

Not by the day, but it does keep changing, while the Caiman remains stable.

How does it compare to your other thingamajiga Steve?

You mean the built in DAC of the Lyngdorf amp? I'll do a bit more comparative listening, but the BM seems a load more dynamic. Had to swap out some Atlas phono cables though for some Linn silvers, which resulted in a much less harsh and more musical presentation.

Just my two pennyworth, reckon issues that I've read about more likely to duff units. It happens.
How can you have variable burn in issues ? Doesn't add up.. sounds like specific issues with those bits of kit.

No way that I could describe my BM as having muted high's.. even from the minute it was powered up.

Easy to have variable burn in IMHO. I've heard it with coupling caps and also a new valve amp. Sound would get better then worse again, then better again.

That burn-in pattern can happen with cables before they settle down.

But.. to the extent that has been described?
Ok... I'm surprised.

[Ali Tait]

Well the changes were easily noticeable to me.

Fed-up with lack of progress on the burn-in front with my BM, I resorted to the Maplin XM-20W PSU Stan recommended for the Caiman. I have been using it for a number of years with the Caiman. It kicks-out 15V vs. 12V with the stock BM PSU (the BM is good to 16V according to the instructions). It made quite a difference to the BM: Gone is the mushiness, the highs are back, the bass is deep and tight, the sound stage is much improved - but I still find it tiring to listen too even at quite low listening levels. Perhaps the stock PSU is at the root of the issues some people (including me) have raised.

[SteveW]

Not questioning that people have heard changes.. But why doesn't everyone hear the same thing...?
Mine sounds amazing from cold.

[NRG]

Mine too, its as good now as it was out of the box, no coupling caps so no effect. I believe its in the head...shoot me and as for cables!

What a fascinating read.

Mine has sounded great from the off. A bit of forwardness for the first few hours, but spot-on ever since. I listen to it for hours every day. Still sounds the same. That is, amazingly stunningly good.

What is going on here?

I've a Stan-recommended battery PSU on its way - that'll be interesting.
