Monoblock Suggestion?
"Does anyone have any first hand experience with the Parasound Halo JC 1 ?"Sure, I have owned a pair for 2 years. Initially they were my reference until I modded some older Adcom GFA-585's. They gathered dust for about a year until I finally modde... 
I Don't know JAC about DAC.... help please
DAC's are for CD's only. You might consider getting one that you can add a USB interface to later when you move your music to your laptop or PC. And dont be reluctanct to buy a used one. They dont wear out. 
DAC Help
for Rock, you need dynamics, not warm, soft sound. Try the Birdland Odeon-lite. Great right out of the box. One of the few DAC's that sounds good even without mods. The others like this are too expensive for your budget: Electrocompaniet ECD-1 and... 
Some digital comparisons: cables,transports&jitter
The article I wrote for PFOnline explains some of this:http://www.positive-feedback.com/Issue14/spdif.htm 
Learned about DACs, need help to take next steps

DAC for Linn Gear
You could easily get the transport modded to add a S/PDIF coax out. The DAC's you mention are mid-line, but inexpensive and pretty good values. You should also consider using a laptop with a USB interface to drive your system. This will be superio... 
Why do digital cables sound different?

Why do digital cables sound different?
Red - I think you're mad actually, just kidding....I have no explanation other than the usual parametrics, R,L,C and dielectric absorption. Also, dont forget metallurgy.One thing that I didn't mention before was the length/speed effect that I expl...

CD's for auditioning
I do this for a business, so I need the best. I like to use the following jazz track because of the intense piano passages. If your system does these well, without halos, echoes, reverberation or sibilance, then you have arrived:Gene Harris - the ... 
Comparing Bel Canto DAC2 and Birdland Odeon AG
"I believe Audioengr is talking about a modification to the DAC to bypass the volume control. Correct?"Yes, I have done this before. Makes a BIG improvement if you bypass the volume control. 
Any superb balanced dacs up to $2,500 used??
I've had Electro ECD-1, Bel Canto DAC2, Perpetual Tech P-3A, Birdland Odeon-lite, Audionote DAC4, Classe' DAC1, MSB Gold and others I wont mention in my system. IMO, the only ones that sound good stock are: ECD-1 and Birdland. Even of these, the E... 
Great tube DAC's with volume control?
You have to be careful as to how they implement the volume control. The Birdlands just put a resistor divider in series with the output. This is bad if you have any cable capacitance. I usually bypass this pot. 
make-over for amp.
The 105's are great speakers. I would replace all of the parts in the 105 crossovers - this will make them superb speakers. Inductors from Jensen, Capacitors from Multicap and power resistors from Caddock. The difficulty is that you will need test...
