Beresford Bushmaster DAC

[Covenant]

Can we have a little information please Stan?

[CanDAC]

Yes Stan, more info please! I'm on the verge of trying the Audiolab MDAC and don't want to experience buyer's remorse. Thanks.

It's not in the feature and price range of the MDAC.
Basic specs are:
Two TOSLINK inputs
Two Coax inputs
One fixed Line output
One headphone output
Audio frequency range 0Hz to 20KHz.
Sampling freq. up to 192Khz

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.

Main mode of operation:
Manual Select
Auto Select
Stealth Mode
Hunt Mode

Power options:
External psu that is used like a battery charger.
Inbuilt battery low level warning in case anyone wishes to use it with a 12V battery.
Uses an enhanced version of the low noise VirtualDC circuit from the TC-7510, which means that there are no muting relays or muting transistors required in the DAC.

Low power consumption. Typically 70mA under most conditions.
Self levelling feet. Less than 170mm wide, and 220mm deep.

Price is not yet certain until I have an actual idea of the cost of production. But £125 excluding VAT and shipping is the aiming point.
Meant to replace the TC-7510 and Caiman+.
Not expected to be shipping till January due to some miscalculation in the delivery schedule. Was supposed to be ready in October...

Good luck with it Stan, sounds like a cracker

Audio frequency range 0Hz to 20KHz.
Sampling freq. up to 192Khz

Surely you mean nearly 0Hz to 90KHz+? I could understand it if you only had a maximum of 44.1KHz sampling frequency, but if it'll take sampling rates of 192KHz it should have an audio bandwidth of approximately half that no?

Most of the features are the ones that many people have requested, including the price point. Some features are unique to the Bushmaster, and might even be unique enough to have been patented since they were invented by me. I expect other designers to try to copy them however.
I'll go into more details about those features in due course, when the DAC is closer to launch date.

As for the question regarding the audio range: 20KHz is the upper frequency of the audio range. Anything above that has a different name .

Good luck with it Stan man... Although I'm sure you don't need it!
What news of te headphone amp (or have I missed that else where :/)

[Reid Malenfant]

Ok, you got me there Stan Bang to rights come to think of it

[StanleyB]

What news of the headphone amp (or have I missed that else where :/)

As one visitor has already mentioned on AoS some weeks ago, he could hardly tell the difference between the Bushmaster's headphone output and a Graham Slee headamp. Of course, the visitor did not know he was playing with the Bushmaster since he had not seen any of my DACs in person before .

I thought the 7520 was as good as the Nva job I once had, so that doesn't supprise me really ...
The caiman is excellent, although I don't have much to compare it too...

I thought you were making a dedicated headphone amp based on the gator ... Or summat??
There was a point you mentioned something about it when I said I thought my grados and caiman were a little to revealing of digitalness (for want of a much better description) when listening to spotify... You mentioned you had something in the pipeline that might help when I asked about using a different opamp, and that it was connected to a headphone amp you were building? Or did I miss understand??

I've been holding fire on getting any sort of dedicated headphone amp for work you see ... In case you bought something out and I experience, to quote, buyers remorse
