Anyone using the OPPO 105/D s' preamp to drive an amplifier? And the results?? Multi or 2-CH
Thanks in advance to all those who respond.

As an experiment, I once ran my Oppo/Modwright 105 directly into my SET monoblocks instead of going via my Aesthetix Calypso linestage. Big mistake. The music became soulless, threadbare. At least IMHO. I couldn't switch back fast enough :-)
I tried it once into a Parasound A21 power amplifier. Normally I run the Oppo stereo outputs at fixed volume to a preamp. Driving the amplifier directly seemed to provide less bass. I was using a subwoofer connected to the unbalanced outputs while the balanced outputs were connected to my Parasound A21. I seemed to get better bass with my Pass Labs X1 preamp driving both the main speakers and the subwoofers. However, you should try driving your power amplifier directly with your Oppo BDP-105D and see for yourself what the sound is like in your own system. Some people like it better.
Good luck,

Amplifier input Z, gain and sensitivity ( voltage needed for full out) all play a role too.
The A21 input impedance is only 33K using the unbalaced in, 66K balanced and using both at the same time as you did played a role.

I don't use both inputs on the A21; I use only balanced inputs on the A21. I connect the unbalanced outputs from the Oppo to my powered subwoofers. This is exactly the same way I connect my Pass Labs X1 preamplifier and bass is much tighter and stronger using my Pass Labs X1.
My Oppo BDP-105D has both balanced outputs and unbalanced outputs; my Pass Labs X1 preamplifier also has both balanced outputs and unbalanced outputs. I get much better sound quality connecting my Oppo to my Pass Labs X1 preamplifier and letting my Pass Labs X1 drive my Parasound A21 and my powered subwoofers.

Got it, only one plugged in. The Oppo balanced out is supposed to be 4.2 V.I found something somewhere that said the output Z is 100 ohms but Oppo themselves do not say. Should be OK but don't doubt going through the pre you have improves things.

Thanks for all the input.Had considered buying one to simplify the system,either 2-ch or multi.As usual,no silver-bullet.
Can anyone comment on its' DAC performance or as a stand-alone CD/SACD player?
Many thanks.

I've gotten used to the sound quality of my Oppo BDP-105D and I think it sounds just fine. However, I prefer the sound of my TASCAM DA-3000 DSD recorder that I use for recording vinyl to DSD-5.6MHz. It has BurrBrown PCM1795 DACs and it sounds more transparent with deeper, tighter bass than my Oppo.
The TASCAM DA-3000 can not only record digital PCM up to 24/192 as well as DSD-2.8MHz and DSD-5.6MHz, but it can be used as an autonomous digital player that accepts a 64-GB USB flash drive into its front-panel USB port. It can also be used as a DAC for streaming from an external source, but it does not contain a USB DAC input -- only coax S/PDIF and AES/EBU for PCM plus SDIF-3 for DSD.
The TASCAM DA-3000 is one of the most natural sounding DACs I've ever heard.
John,Thank you for the follow-up.
Has anyone directly compared the sonic performance of the 105 and "D" versions?
As I understand it,there was a different implementation of the DAC chips in the two units.The "D" uses fewer chips as the older "105s" circuitry did not sound as good with the "Darby" ,thus the change.
Any thoughts or opinions??
