This is
my first post. I bought Ash’s Bitzie back in the summer. I am still gobsmacked
by the sound that magical little silver box makes. It has made by Audiolab 8200cd
redundant via USB. It has to be the pound for pound champion of musical
enjoyment. The sound & tone of a guitar into a pair of Grado SR325i cans
still makes my jaw drop now!
Am i
right in thinking that options B & C of Bakastra’s post would enable the Bitzie to receive to a
toslink digital source? Eg sky
box optical out> hifimdiy ux1 sabre
usbdac+spdif/usb converter > laptop/computer > bitzie
Would
this work???? Cheers Paul |

To all, sorry guys, we're only able to go to 48k on USB out, and as that wouldn't be acceptable here, it would be best not to bother?
  Mind you, people seem to love the Bitzie which only goes to 48k.  Should feedback be positive, then we'd have a go. If not, then discuss what you like (but this place is not a showcase for other manufacturers  ).Graham |

A GSP ADC would be a niche product in a niche market, and as such would have difficulty in making enough sales to warrant its development - possibly . . .
I would love to have Graham breathe his magic on an ADC having lived with a Majestic since its launch. It's the analogue stage and digital implementation that makes a great digital product, not the numbers on the spec sheet. I used to rip to vinyl at 96/24 for the "best" results - until I actually learned what was happening, and did some comparative rips. 24 bit for vinyl is totally wasted. The extra dynamic range disappears into the noise floor of the groove (just like any residue hiss from a MC phono stage). And high sampling rates - for my ears - confer no benefits over 44.1 or 48. It's the emperor's new clothes syndrome. But with the spec obsessed masses buying kit "by the numbers" rather than by the sound quality, I can see why Graham is reluctant to commit to an ADC "limited" to 48kHz on USB out. |

Graham, thank you very much, this explains everything. If down to 48k, then yes, it would be, as @morris_minor put it, a niche product in a niche market. Extra bits coming off vinyl seem useless indeed. As to higher sampling rates, though, the point is that with a cheaper equipment (such as sub-$300 [asynchronous] DACs, sub-$100 headphones), the difference between 44.1k/48k and 96k is clearly audible. Yes I could believe @morris_minor that with a better DAC this difference fades away. (I am yet to check this myself: I hope Majestic makes it to the US lending program before all 200 units have been sold!!) On the other hand, most people would not have better DACs, so there would still be the demand for 24/96 vinyl rips. And of course nobody wants to see the favourite brand associated with some limitations, and then GSP is completely right to be into what he does best: the analogue components. Graham, I believe this also shows that you found some analogue-to-digital conversion method which completely satisfies your needs; could you please PM me what it is?

I don't really need to be secretive about it. Any decent 48k USB codec chip that has data IO - because all the A-D would be handled by something better, and by that I possibly mean an 8804 transceiver and a decent A-D chip from Cirrus/Wolfson. However, the analogue audio quality going into it is another matter. You can digitize old rope and get... old rope. What goes in comes out, and if what goes in is not right, it doesn't matter if it's 48k or 384k.
All the above is academic because if I can't sell 400 every 12 months, I won't even plug my soldering iron in. If that sounds a bit big-headed of me, then I'm sorry. I've had enough of trying to offer good sound to a 'deaf' digital audience. |

400 a year is about 34 a month! With only three of you building units would you even have time for an ADC?
How about giving your new "Super" phono amp a USB out? (He says, only half seriously . . .

I am glad that Paul is enjoying his Bitzie. Just need someone to buy the spare one I have left. A truly fantastic audio product. Anyone who disagrees must not love music at all. It really stands as a middle-finger to the know-it-alls who judge products only by specifications when they clearly don't understand what they're talking about.
Paul, the SR325i isn't anything particularly amazing IMO; there are cheaper headphones that thrash it. Also, about your Bitzie connectivity enquiry, the USB is needed for power as well as signal so this is the only input. The S/PDIF coaxial and optical on the rear panel are only outputs, to send digital data to a receiving device. I must admit that I would have liked to see a Bitzie with scaled down Majestic connectivity; oh well, I'll have to buy a Majestic instead. Edited by Ash - 16 Dec 2014 at 9:11pm |
