You can't please all of the people all of the time ;)

I look forward to that, Stan. Some of the effect of greater impact is by virtue of running balanced connection (I find that always to be the case), which explains why I keep asking for balanced outputs in your next design :)

Hi Stan, with all due respect, the DAC chip has filtering and a line driver / DC servo built-in to the chip... it's a bit misleading to market your product as a sort of "passive" DAC that doesn't need an 'audio stage'...

It is not the first time that you have thrown accusations in my direction and it is high time I address it.
Where exactly have I marketed my product as a passive DAC?

Hi Stan,

From http://theartofsound.net/forum/showpost.php?p=263326

"Other technical details:
No audio caps in the signal path between DAC chip and RCA/phono sockets.
No opamp output stage.
i.e. it is a fully passive output DAC."

It isn't a fully passive output DAC as the chip has a built-in line stage.

PS: I obviously don't have a problem with you or your products as I do openly recommend your products e.g. http://theartofsound.net/forum/showthread.php?t=25579, but your comments to Martin regarding dynamics, to me, implied that external output stages colour or change the sound, but your DAC doesn't (despite having an output stage).

As far as I'm aware a fully passive DAC would be a multibit current output DAC with an I/V resistor and (likely) an output transformer to add gain...

Thanks,

Neil

If you wish to twist my comments into something else that suits your agenda of demeaning the Bushmaster you are certainly exposing yourself repeatedly.
The information you point to is certainly not a marketing leaflet and dates from 03-11-2011, which is way earlier than the release of any new DAC from me.
The BM was released in the middle of 2012 and I have stated the technology employed by the chip manufacturer on numerous occasions. I suggest that you contact them and point out to them that their stated technology is a marketing scam. I don't see the point of you making your own interpretations of what is written unless you have deep seated alternative motives. Maybe you are working for a competitor or have commercial interest in a rival product?

Shall I call the fire brigade? :rolleyes:

Naah. It's time I put Neil to task on his long standing attack on me and my DACs. I am getting fed up of people like him who constantly try to shaft British talent and skills in preference to Chinese designs and non-UK component manufacturers.

Stan, you write with considerable prejudice and rancor, and it's not very appealing (I didn't expect you to answer my sound quality questions, because that wouldn't be fair - or smart marketing). Not only do I know from experience with a living room systems back in the '80s and '90s that cost and sound quality often don't go together, I'm also relatively speaking a cheapskate. For example, I've got a wonderful (for its price range) MyDac on my living room floor, one that not only sounds pretty good but solved my TV/media box-Toslink switching problem with the Audioengine D1 (sound dropout). However, the idea of paying 369 USD plus transportation (four times) for a simple 2.0 setup strikes me as too much, even though I can easily afford it. That's why I've been plumbing the lower price end of the market looking for worthy alternatives. That led me to post here in another thread asking for suggestions, and that's how I got steered to Beresford. Unfortunately for practical purposes, you're in England and I'm in the States, hence buying is an all-or-nothing crapshoot. That's why my few questions to clarify some reviewers' comments, as well as to get information about your product that's currently unreachable on your website (bugs).

What are you doing Stan? May I suggest that you sign up for a course in public relations as a matter of urgency, either that or employ someone to do it for you because it is definitely not your forté dude... :eyebrows:

When someone interested in your product asks pertinent questions about its performance because they happen to live 3000 miles away and want to be as sure as they can that they are buying the right product, you do not get all defensive on their ass and launch personal attacks on them. Also, why are you so quick to accuse people of being anti-British when you are backed into a corner? It ain't cool dude and you of all people should understand that. This has the potential to damage your business Stan so please try to stay cool because it would be a terrible shame if you blew it simply because you cannot handle simple customer relations issues :(
