Title: Setup suggestion for Ayre QB-9DSD
Post by: south on August 29, 2014, 01:22:28 pm

I am not sure which of the many setup options to use for the  QB-9DSD.
Mostly listening to ripped CD's on a Mac Mini using stereo speakers.

The QB's specs are:
 Frequency Response
DC - 20 kHz (44.1 kHz sample rate)
DC - 22 kHz (48 kHz sample rate)
DC - 40 kHz (88.2 kHz sample rate)
DC - 44 kHz (96 kHz sample rate)
DC - 80 kHz (176.4 kHz sample rate)
DC - 88 kHz (192 kHz sample rate)
DC - 80 kHz (2.8224 MHz sample rate – DoP )

Input
1 USB
PCM 44.1 kHz, 48 kHz, 88.2 kHz, 96 kHz, 176.4 kHz, 192 kHz (up to 24 bits), DSD64

Would your suggestion change if I began to listen to more downloaded songs at Sample rates: 96kHz/24bit or 192kHz/24bit?

Generally I prefer to listen to music at the native rate, unless the DAC has issues with pops & clicks when it switches sample rate.

I would just set the Output Format DSP to convert:
 

<44.1 kHz
352.8 kHz
>384 kHz to 176.4 kHz

and 384 kHz to 192 kHz

I would leave the rest at "no change".

I cannot modify the box containing the specific sample rates to change/leave.
Which setting will allow this box to be modified?
Currently all signals are being output at 64.
