Beresford Bushmaster DAC

[Clive]

What about putting a cap of whatever value between amp and speakers to block any DC offset inherent in amplifiers? Would it have a detrimental value? And has the DC offset voltage from anyone's amp ever demagnetized or magnetized anyone's speakers?

For sure I doubt that <1mV will magnetise a TVC but I don't know 100%. Had it been 500mV then probably it would be a problem.

This is tremendously long thread, are the Bushmaster specs still as declared at it's start?

Only a couple. Frequency response is now from DC instead of 0Hz. I left out the self leveling feet. And the price is still not finalized. I won't know that till we have had all the invoices from the various sub-contractors who are doing the case etc. for me. But whatever happens, nobody will have to pay more than £200 to get one delivered via a regular postal or courier service, no matter where in the world they are.

Your'e charging £200 for delivery????????????

It's ok Stan, it's just the way your post seems to say that!

Well if you had said that in the first place!

Brian, there was a time when I followed the accepted convention and went along with whatever design recommendations engineers far smarter than me would dish up on a plate for all of us to take in as the only solution. But times have changed and I started developing my own alternative views on how to get more bangs for bucks. The Bushmaster is not something that I just knocked up in my shed overnight. I have been working with various international IC manufacturers for several years now in order to see what can be achieved with their components in my design. Now that I have a recognized presence in the market, I have access to a lot more info and R&D assistance from some component manufacturers.
The DC output from the DAC chip is irrelevant in the case of the Bushmaster. The IC had been specially designed, tested, and certified by the manufacturer for just that purpose and has been used successfully in some extremely expensive kits in the same configuration. Additionally, I have had beta testers test out the Bushmaster on a wide range of kits in order to satisfy myself of the soundness of the design.
So whatever other path DAC manufacturers are following or not following is of no concern to me. I put my trust in the component manufacturers, who developed the parts for use in the same configuration that I am using them in.
To think otherwise is pure speculation on your part, or you have been badly informed on some other forum.

Think of how good the Caiman is...

Stan made that.
At £200 I'm sure the Bushmaster will be WAY better than any other £200 Dac out there


(...and the rest)

I'm sure it's going to be great - and I'm well aware from elsewhere how modern chipsets have moved on in recent years When I look at the extreme complexity of my own CD player with "miles" of wiring and loads of components in both digital and analogue domains, I really wonder how all this fudging made the CD94 based players sound any good at all

[Gazjam]

'tis true...
Rega Dac/Mdac comparisons will be the proof of the pudding I guess....

Have faith in Stan, sure it'll be a cracker.
