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

Oppomod transformer is said to give nice sonic improvement.
Cheap over the long run.

With your budget, you could try a Naim nDAC combined with a Teddy Pardo TeddyXPS power supply.  Excellent sounding and very well built, both by companies with long excellent track records re service.  The pair would be under $2500.  The combination will see off any of the standalone DACs mentioned above. 

If you really wanted to go nuts and add streaming, you could do a used Naim NDS with the same Pardo TXPS; though an NDS would be $3-3.5K on its own (the Pardo TXPS is $1099 new) and requires a separate power supply. 

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.

Did I say discrete jpeg?  It's been a long day:  Discrete JFET.

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.
