Add an external DAC. Make my Oppo UDP-205 a true top player


I am not sold on my Oppo UDP-205 audio reproduction.  .  It plays all formats, but audio needs improvement.   Looking for audiophiles that have felt the same a bought a DAC..  Which one did you buy.  What works really well?

What’s your budget? I have a 205 as well and still stock that I don’t really use as my Cambridge 851C to my ears sounds more refined so I agree the Oppo is really good for audio but not really, really good. I use the DAC in my 851C as well for my Bluesound Vault 2 as it punches above the DAC in the Vault, but I’m considering adding a DAC that beats my 851C so I’m reading all the reviews here and one thing I’m considering is sending my 205 into ModWright and let Dan do his thing. I have a ModWright preamp and one before so I trust Dans work.

Dacs I am considering are the MHDT Orchid, Denafrips Pontus, RME ADI-2 and to name a few. These DACS can be had for less than the cost to upgrade my 205 so I’m kind of leaning this route. If I didn’t already have my Cambridge spinner then the decision to send my Oppo to Dan would probably be a little easier.
I felt the same about my 105, which I only used for SACDS, DVD-A etc and had a separate trans/dac for redbook. After many years my Pioneer PD 65 with level 3 Musical Concepts mod (+ outboard PS) , alas,about 2 years ago the laser died and is no longer made. This forced me to use the 105 for both and I was not happy. While I searched for a new trans, I came across replacement Oppo 105 power supplies on Ebay and a replacement IEC with pure silver tail that attached directly to the OEM PS board. It was pricey, but damn what a revelation. Now that I had the lid off I could see how easy it would be to upgrade the PS. Ebay options ranged from ~ $150-$300+. I went somewhere in between

I eventually got a new player/trans- a Marantz HD CD-1 which is excellent and was plugging it into an Audio Alchemy DDP-1 + PS 5. After several months I was jonesing for some DVD-A & SACD, but to play SACDs I had to plug the 105 direct into my then new amp (EVS 1200 dual mono class D: see my AGon thread) using the 105s VVC. Now my system is 100% Dif balanced (which in spite of the ignorance spewed in audioland is the only way to go) it sounded great. So great in fact that I have not gone back to my AA DDP-1 + PS 5. FYI, I use WireWorld Series 8 XLRs, and speaker cables which allows everything in front to shine
BTW, I owned quite a few Class D amps over the last 10 years, none compare to the EVS 1200, but I haven't heard GaN yet, but coming soon

You REALLY need to give a budget. That being said, I’m really happy with my W4S DAC.
I am extremely happy with my Modwright Oppo 205. It has a very good DAC to begin with and after Dan hot rods the output stage it’s killer.

You don't mention a budget, but neither do you specify in what respects the Oppo is lacking.  Resolution?  Air? Warmth?  Spatiality?

There are dozens, no, hundreds, of DACs out there that will take you in one or more of those directions.
