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?

Agree that a separate DAC is a much better deal than an expensive mod of your Oppo. My Oppo is a 105 and I chose an LKS MH-DA004. Monster linear power supply, dual DAC chips, 3 femtoclocks, discrete jpeg analog stage and built like a brick. About $1500 with Amanero USB board. There’s a long thread here about it. I see now that it has a US distributer.
i have a Oppo 105 and would like to add a external DAC that would rival the SQ of a 205 without the huge price upgrade of a used 205. this is 2020 4 years after the introduction of the 205. for a grand their must be something? any 205 owners find anything?  btw, the LKS is no longer available.

You write: "btw, the LKS is no longer available"  

But I see it is available from Amazon, apos.audio, shenzhenaudio and various ebay sellers.  How did you come to this conclusion.  And why?

Also the LKS mini dac (similar but just one DAC chip) for under $1K.
I have a 203 and am using it as an endpoint with Roon. The 203 is Roon Ready but my problem is that the 203 will not unfold Tidal MQA files and I need a DAC that will do that so I can enjoy the full benefit of Tidal.

I've considered purchasing a streamer/DAC but I am wondering if I can simply purchase a Roon Ready external DAC to connect to the 203 and solve the problem. 

Does anyone know if this would work and what I would need to do to set it up?

Thanks for any guidance.
