It was not envisaged during product development that this was to be a usable sampling rate and as a consequence your Rega Dac may therefore occasionally have problems consistently locking onto a 176.4khz signal.
The good news is that all Rega Dacs dispatched from May 2011 onwards have an update to accomodate 176.4khz and, where appropriate, the update can be by done by Rega HQ or their designated overseas distributor.
Just for the record, I'm really happy with my Rega DAC and don't regret the purchase one bit. It wasn't my intention to put any pressure on anybody by posting here about the glitch my unit seems to have with USB - if I wanted to pressure anyone I'd be seeing my dealer.
Fact is I don't much care about built-in USB because I have an Audiophilleo USB-to-SPDIF converter. I was just wondering really whether the remedy for 176.4kHz support might happen to fix up my USB port at the same time.
Either way I'm sure it'll get sorted under warranty. These things happen.
Do you use the Audiophilleo to take advantage of assynkron usb?
Look forward to your summary on this!
Could the Rega dac have the potential to expose the stupidly overpriced Naim's & Linn's of this world!
