Thoughts on using the DAC in my oppo 205 with a CD Transport.

Well, it seems my thinking has been flawed. I'm happy I decided to post about this, as I probably would have decided to try the CDT route.

So now having to shift gears, can you guys offer me thoughts on DAC's (would like to stay under $1500) and not opposed to buying used. The Gustard A26 sounds like a possibility, it has a nice assortment of inputs (I do want optical, coaxial, and USB) to keep most future options available.

I also saw the  BorderPatrol SE-i DAC looks nice; I like the fact it's made in the USA. But basically priced a bit high for me, also no optical input option.

Open to suggestions.

Chord Qutest, Benchmark DAC 3, Bryston BDA-3 (closer to $2k) 

Chord and Bryston are more musical than benchmark  

There are others but I listed what I had experience with  

It's the DAC in your Oppo that's holding things back, not the transport.  I use my Oppo as a transport, sending the HDMI out signal to a much better DAC.  It sounds like you've figured out that is the route to take.  

With those beryllium tweeters, you might want to look at R2R or FPGA DACs.  Sorry, I don't have a specific recommendation, my last DAC in that price range was the MHDT Labs Orchid, which is very good, but probably a little outdated compared to some of the newer offerings.

I used to have a Gungnir multibit and it was quite good. They have recently updated this unit to v2. This checks most of your boxes, and is made in the U.S.

MSB, which is no slouch of a company, used to base their universal disc transports around the Oppo 103; they kept the loading tray and transport mechanism but took out the Oppo DAC and changed everything else, including a separate matched power supply. So yes, you'd likely want to keep the Oppo as a transport and upgrade yer DAC.
