Digital Amps - Your opinions and why so few?
Panny - your XR45 can sound as good as the Carver ZR1600 with the exception of bass control. This is the only edge that the ZR1600 has over it, once they are both modded anyway. This is the only way that I will listen to either one. Before mods, I... 
Advice on Budget System for newbie
I would highly recommend the Panasonic SA-XR45 or the new SA-XR70 (avail. in Oct). These are in the $400 range HT receivers with 100 W/chnl digital amps for all channels. They can be run digital in to out and sound good stock, but are superb when ... 
theta tlc between transport and dac benefit?
The DIP is designed well, but implemented poorly. It really needs mods to sound good. Also, the clock in it is not stable, and this is the whole reason for it's existence. If the clock is replaced with a Superclock2, it works very well. 
What's the general concensus on Wavac amps?
If you want the best that tubes can be, this is it. 
Digital Amps - Your opinions and why so few?
ZR1600 is a good choice for planar speakers. There are several mods available for it. I compared it head-to-head with JC-1 monoblocks and it controls bass better than any amp I have heard, including the JC-1's. Here is a recent shootout:http://www... 
birdland odeon-Ag VS Perpetual Tech P1A/P3A/P3
"do you know anything about Benchmark DAC1? how do those two sound different??"I have not heard the Benchmark DAC. Only got feedback from customers that do shootouts. No comparisons to Birdland, though. 
Special digital cable needed?
Satch - this article I wrote for Positive-feedback explains it:http://www.positive-feedback.com/Issue14/spdif.htm 
Looking for advice on amp/pre amps...
The best solution in your pricerange is a Panasonic SA-XR45 or SA-XR70 (due out shortly). These are around $400 and give you 100 watts per channel. They can be modded for around $1000-$1200 and sound superb once modded. You will not be able to ach... 
Chord 64, ECD-1, Audio Logic, Dodson DAC opinions
Dodson is the best unless you are after a "warm" sound, in which case the ECD-1 would be the best choice. If you want the "tubey" sound, the Audio Logic is a good choice.

Special digital cable needed?
75 ohms characteristic impedance is beneficial, but not necessary. If you want to minimize jitter, then stick with 75 ohms and get a 1.5m length minimum. Ask someone with digital and transmission line experience for advice. Read this article I wro... 
Modifying a cd player to use as a DAC
Non-trivial, but it can be done. Probably requires adding a CODEC chip and some switching logic for LRCLK, BCLK, SDATA. 
ATT / ST Optical Cable?????
here is a very good one that I use:http://www.soundprofessionals.com/cgi-bin/gold/category.cgi?category=220&item=SP-TOC-99HQ&type=store 
Need opinion for Pioneer Elite DV-47Ai?
The PD-65 is old technology in comparison. The DV-47AI is better in every way, except the stable platter. Much more mod potential as well. 
Monoblock Suggestion?
The problem with Innersound, Coda and Continuum (all designed by the same guy) is that they dont use global negative feedback. This makes them very airy at the HF, but at the expense of bass control. I have three Codas myself that I use for HT.
