Need DAC comparable to OPPO BDP-83SE, or better, small size, USB OK, SPDIF coax...

Though my system will not be very expensive it will sound very very good with the right DAC. The Slimlines I bought directly from Bruce Edgar, oil filled caps, foil inductors, upgraded resistors and wiring as well as Fostex tweeters. Baby sophia has every upgrade I could find to do and good tubes with several sets of spares. I have made all my own cables for decades and heard them up against many very expensive cables, I will stick to DIY:) I will also run a dedicated power circuit for the sub amp and one for the rest of the system, hospital grade sockets and line filtering of some sort.

I just need the right DAC to match the system for the lowest possible price though will spend more as needed. We love listening to music, not the system, this will be more than good enough for our needs and for being in an RV, outstanding. We know horns might not be the best to position but will work on it as require and use room treatment as we can. This is a very solid RV, 5k more weight than any other 5th wheel ever sold.

I do not need or want anything wireless, all wired connections as not having wifi in the RV since fully shielding it against outside RF. On occasion will turn on the Wifi but not for long so that makes using the Tab a bit complicated unless using the audio out but want to use the USB-C

Adioquest dragonfly dac is the size of a thumb drive and gets very good reviews.  

Thanks, I was taking a good look at that exact DAC then I looked at the need for something with more inputs and outputs but best I found was one with more inputs and just one set of outputs but I can work around that. I just bought a used Topping E30 after reading many reviews on many DACs. Once I get it I can compare it to the OPPO player and the DAC in the Vision X sound bar. Hopefully I will just use the Vision X internal DAC and the E30 on the mini computer(or sff computer).

I got the BD drive on my high end laptop to finally work late last night, then looking for external case and cable to use it with the HTPC in a mini computer but so far it does not look good if I want to record and disks as backup storage for any media we have and may buy in the future. I might have to buy a new drive but they are only $100 for a decent one. It has to be a newer mini computer to have 4k 60hz as well. I can get a bit older and bigger than I want at 11x11x3 sff computer, upgrade the video card, put the BD into the DVD slot, use the E30, done:)

 I found a site last night with the proper edit needed to get Windows 10 to see the BD drive in the laptop and it worked, CD, DVD and BD. The laptop has a good video card option I ordered when it was custom built but they did not tie it to the upgraded GPU, it uses the CPU graphics instead. Not a problem as I want to keep the HTPC separate from the laptop anyway.

 I have been looking into all angles I can think of, long before posting here, found answers or at least a road to travel last night but certainly still open to suggestions and advice!

Thanks again,

Rick
