Meier Audio StageDAC - Page 2

post #16 of 633

Thank You for your extensive post Mr. Meier. I truly appreciate when manufactures take some time to anser/post some information abute their products.

I will put in som extra hours and see if the economy will allow a purchase of this undoubtly fine DAC.

Thanks again

Best regards 


Edit: I agree with Joseph that a 24/96 usb input should be available. Maybe for an extra charge, if price is a concern?

Jan, could you tell us about the output stage of the DAC? Will it be opamp/buffer?

Dear headfellows,

> That's slightly higher than I was hoping for

Well, currently I’m working on a slim version of the STAGEDAC. I’m not sure yet whether it will be produced or not but this one could be interesting for you.

> I feel somewhat unimpressed, to say the least, by the USB input. I assume you choose the easy path (sorry) with some 270x chip, but every day there is more people looking to use the computer for access 'HD' tracks, so a 24/96 USB input is mandatory.

In principle it is well possible to implement 24bit 92kHz USB using for instance the TAS1020 USB streaming controller chip. However, this would require extensive microprocessor programming and thereby expertise and resources that I simply don’t have. Such solutions are only feasable for big companies who build their devices in larger quantities. To add such a solution to the STAGEDAC, which is only build in small numbers, would increase the sales-price considerably. People would do much better upgrading their computer with a S/PDIF output.

At the direct signal paths LM6171 are used (biased into class-A).

Inside the crossfeed paths AD8610 are used.

That's interesting indeed. I absolutely love the HA2 MK2 I've got and given its quality/the Meier history, I know that either way (Slim or Full) it will sound great.

I'm impressed by the DAC in the Symphony and consider it absolute high-end quality (enormous detail and clarity). If the StageDAC is even better (direct quote Jan Meier), I don't know what to expect, especially since Jan is usually very modest in his product descriptions.

Hi Jan,

Thanks for your reply.

For 24/96 'easy' USB, you must look for the TENOR TE7022L chip, but outside Corea (Audiotrack) I am not aware of nobody using it (well, you may be first ). It is a one-chip solution (see their Prodigy Cube product). Very interesting

Cheers

Josep

Congratulations.
But... I feel somewhat unimpressed, to say the least, by the USB input. I assume you choose the easy path (sorry) with some 270x chip, but every day there is more people looking to use the computer for access 'HD' tracks, so a 24/96 USB input is mandatory. I know I can have USB->SPDIF 24/96 for not much (say, Prodigy Cube) but... well.
I want 24/96 as well.

with 24/96 it would be a perfect match for computer sound.

As far as I understand, it does 24/96, just not via USB.

M Audio Transit 24/96 over USB

M-AUDIO - Transit - Hi-Resolution Mobile Audio Interface
post #26 of 633
She does (Transit 24/96) but needs drivers, and it gave me trouble with Vista. But it is not exactly a new product (is on the market for some years) so it is surprising the scarce options we have for USB 24/96...
post #27 of 633
This looks fantastic and I will almost certainly be buying it... Jan, do you have the dimensions of the case?
post #28 of 633
It is very the expectation!!!
post #29 of 633
Dr. Meier: Just want you to know that many of us are definitely looking forward to this coming stand-alone DAC. Many things you mention such as jitter rejection, wide-band cross feeding, and tunable soundstage are so interesting, as the new Lavry DA11, but yours is also so SQ-oriented with best performance-cost ratio in mind. I really like your approach and concept (as the Arietta I have from you.)

Please keep us updated from time to time!!

Wow this looks really great! I will have to add yet another thing to save up for
