Theta DS Pro Gen V or newer?

System details: I presently have a Sony DVD (S560 if memory serves) as a transport, and I just sold my EAD DSP 7000 d/a. A new transport will follow the purchase of a d/a. The d/a will be connected to the Coda Technologies FET 04r preamp with balanced audioquest Viper. Balanced Viper also connects my preamp to my Coda Technology Model 11 amplifier. Biwired audioquest Midnight III connects to my North Creek Music System Rhythm Revelator loudspeakers.

I am on the verge of buying a replacement d/a, which is the subject of this thread. I am strongly considering a Theta DS Pro Gen V for around a $1000.00. My question is this: could a $1000 be spent better (i.e. should I get a newer $1000 d/a like an Assemblage or MSB piece that won't have the parts or build quality of the Theta but will have some newer features like 24/96 processing ability)?

It seems to me that over the last half-decade or more most of the resources of the “big boys” in the industry have been devoted to AV products, with little or no significant development occurring in the top end 2 channel d/a products. I know that dCS, Meridian and a few others have some new noteworthy 2 channel d/a’s, but $1000 won’t even get me a short peek at those pieces. I can observe the changes due to the “trickle down” from the top end products’ features/qualities to the lower end products over the same half-decade, and this is the crux of the question. With a $1000 in mind, are there really any better products than a Gen V? Build quality matters, and parts picks make audible differences in sound quality. I know it's such a broad question, but here are some of my considerations:
1. I need solid analog output section. This is very important for everyone, and is very frequently overlooked. Theta's analog section is truly top shelf to my ears.
2. Upgradable. The Theta is totally upgradable, but it can be quite expensive. Some other brands are upgraded too. The thing about upgrades is that sometimes they just don’t make any economic sense. So, this isn’t a huge factor for me.
3. Given the Red Book standard and all the experience/hype about 24/96 upsamplers and such, is a newer d/a a better move now? It’s my understanding that the Gen V can only pass 48K, but would have the ability to take advantage of the 24 bit input of an upsampler.
Thanks for your thoughts,
