Theta DS Pro Gen V - can you tell me about it?

I have a Gen III and am considering upgrading to a Gen Va,as my Gen III suffers from a hyped-up sounding upper midrange. However, what I am gathering from Rayhall's comments is that the Gen Va does not obliterate this characteristinc altogether.

I am also considering modding the Gen III with High-Quality caps to smooth out the sound. I want to make the best re-use of the Theta's power supplies. I want to retain the dynamics, but end up with a mellower tonal balance.
Any suggestions?

how can I upgrade my theta digital DS Pro Generation V dac or ho can upgraded for me.

Hi Budda888.
The Theta DS Pro Gen V has got some real promise for RedBook Cd replay. it uses a PCM1702 R2R ladder multibit dac and it has HDCD as well from memory.

If you get it cheap enough and know someone that could mod the analogue I/V and output stage to todays current thinking, it could be very very good for Redbook Cd, better than todays Delta Sigma based dacs, for Redbook, even expensive ones.

If you have a good tech show him this thread on great feedback free I/V and output stage, should only take 1 or 2 hours to mod. parts are around $20 for 3 x stack per channel of AD844's

I still have a Theta DS Pro Gen Va. I used a Muse model nine S as transport with an AES cable. The Muse by itself was nearly comparable. With a good transport it is hard to beat for redbook. YMMV
The Gen Va will decode wav 24/96 (at 20 bits , which is not unusual). It will not decode 24/96 MLP. I don't think it has HDCD. It uses a propriatry filter, perhaps equivalent to a MP filter today. It has a great audio stage. I used it with a M2Tech hiFACE to drive files from my pc USB TO A bnc cable to the theta input where i replaced the rca jack with a bnc.
The sound with this low jitter feed was very good. I think the audio section is so good,it would not pay to mod it.
