Variable output cd players
The McIntosh MDA1000 is an option if you want to keep your current player as a transport. 
The black hole of component repair?
Looks like my fix wins the Fastest Repair Award so far... 
McIntosh ss preamp vs. ARC tube preamp
I can't vouch for the ARC tubes (although I will try one some day) but my little C712 was significantly nicer than an LS-3b I had. It was much more involving, 3 dimensional, and just sounded more natural in general. I don't know if this helps you ... 
The black hole of component repair?
I had to send in my warranted Sony SACD player because it quit reading SACDs (funny enough). It took 3 days to get it back! I was shocked and elated - sorry you haven't had the same experience as me. Arthur 
McIntosh MC402
I just wish the 6900 had the same digital volume control as the preamps. I guess the replacement model will. 
Preamp or Amp?
In my experience, changing the preamp has made a significantly larger difference than changing amps. There is a lot more circuitry in a preamp and the voltages are low-scale so this adds up to a bigger difference in sound quality realtive to desig... 
Mac 252, 353, 402?
There is talk in AA about how monoblocked 275s are much better than a 2102 so you may be on the right track. 
Plinius 8150 to MacIntosh MA6900 for bass control
Not only does the 6900 have an equalizer but it has a loudness switch that will compensate for the Fletcher-Munson curves at low volumes. I wish my current preamp had one.I am only familiar with the 8200 mk2 but as I recall, their sound is more si... 
I need a warm sounding power cord.
I think the MIT Z-cord mk.2 is simply awesome. With it, the noise floor drops, the dynamics pop out, and 3D imaging walks into the room. However, it doesn't really add warmth but instead takes out HF noise which sounds bright, if that makes any se... 
isolation transformer vs line conditioner
We are senior electrical engineering PhD students. We know the difference between dirty and clean waveforms. The cores were custom nickel and molybdenum alloy EE cores which are already much better than most commercial-grade transformers. Toroids ... 
Full range speakers with small footprint?
Totems and Royds may work for you. Arthur 
isolation transformer vs line conditioner
The transformers I was talking about were used in power converter applications - granted they were mostly nonlinear applications such as resonant topologies and voltage source inverters but it is still clear to see what impact is on the the wavefo... 
Colorizing The Sound
I agree the DK is a little cool-sounding. However, I don't think your equalizer will fundamentally change that. I bet you end up with a different amp in the end. Let us know how it goes. Arthur 
Quick Question
There is no simple explanation unless you have the impedance curves which you won't be able to get (at least for the amp). Your amp will be fine with those speakers so long as you don't crank the volume too awfully high. Let your ears be the judge... 
what to think about when matching pre and amp
You will never find enough information to really "know." All you can do is try and see if you like it. Don't get hung up on the numbers because what you need are curves which no manufacturer will give you.
