Beresford Bushmaster DAC Reviews

[jandl100]

I bought the linear power supply for the Bushmaster from Mains Cables r Us. Seems crazy to buy a power supply that costs more than the DAC, but it really is like a different DAC now, and SO much better.

I found the same kind of improvement using the rather less costly S-Booster "Best of two worlds solution" linear PSU available from Mark Grant.

Has anyone compared the two PSU upgrades for the Bushmaster DAC?

My Paul Hynes PR3-16 based PSU still sounds superb. Don't discount that for self-builders.

Yes, all the add-on PSUs seem to do a good job with the BM, it would be interesting to have a shoot-out!

Would any type of linear psu work better than the one that comes with the BM?

I tried to order either the SBooster or linear PSU (can't remember) but the site said that there is no shipping to the USA so I was wondering if any linear type PSU would be better? Would 13 or 14V be better than 12V

The Bushmaster manual says that it can take up to 16V DC input. This is what my Paul Hynes PR3-16 is set to. I think the regulation quality is more important than the absolute voltage, so no, Bobby, not any old linear PSU will do. It needs to be a well regulated, low noise supply.

Didn't Stan make a big thing about supply isolation in the Bushmaster though? This should give it greater immunity to the supply fed it I reckon.

I find it's as critical as any other DAC, in other words quite critical of its supply quality.

Hmmmm, I'm not yet convinced

Are you back from holiday Neal? Still want to try that supply?

[NRG]

Yes Nick, maybe in a weeks time...I'll drop you a PM when ready.
