I know exactly what you mean by your system being revealing. My B60 and Audio Physic Yara Evolution Bookshelves are ruthless of everything upstream. Even though they don't have metal tweeters, they still shine a light on any flaw, well, as much as anything can at this level of gear anyway.
Newer DACs only really have a couple advantages IMO...
1) Jitter reduction/reclocking
2) USB input and/or asynch USB
3) High-res capability
Those can equal better sound, but if your catalog is pretty much all redbook and you're not using a computer as a transport, they can be insignificant things IMO.
As I said in a previous post, there's no substitute for a good power supply and output stages. The entry level DACs pretty much all use wall-warts and op-amps. Both are pretty compromised IMO. Yeah, you can get a better power supply like the Pangea unit and/or roll op-amps, but why? Put that money towards a better DAC IMO.
When Bryston developed the BDA-1, James Tanner (VP of Bryston) said they were very surprised how little the DAC chip made. They said it made a difference, but no where near the difference that different power supplies, input stages and output stages made. That was in response to people asking why they used a Crystal chip rather than the flavor of the month ESS Sabre chip or others.
I own a 15+ year old Theta Cobalt DAC. It was their entry level DAC at the time, costing about $700 or so if I'm correct. I auditioned the MF V-DAC and DAC Magic in my system. They didn't hold a candle to the Theta. If DAC technology has come so far in the last 15 years, how come those DACs paled in comparison? The Theta has superior parts all around. It took $1k-ish DACs to get me to open up my wallet without reservation. I also heard the Benchmark and W4S DACs in my system, and the Rega DAC was an easy choice for me. The only sub $1k DAC that had a realistic chance was the Arcam rDAC. The Rega DAC was far better side by side, so no regrets.
Two DACs that get a lot of favorable press around here in the $1k range are the EE Minimax (whatever the current one is) and the Havana DAC. I heard the previous EE DAC, and it was very good. Not exactly my cup of tea, but very good nonetheless. Haven't heard the Havana DAC. From what I've read, I'm lead to believe the Havana and Rega are very similar.
If you want me to get more specific as to why I chose what I did or didn't choose the others, I'll elaborate.
