Two Preamps Into 3 Channel Amp
Is it ok to use two preamps with the Anthem MCA 325 amp in this configuration? Not an good idea to connect both RCA and XLR input into a power amp channel without a selector switch. It is possibility to damage the power amp input stage or preamps ... 
Driving different pairs of speakers with different speaker wire lengths
Instead of two stereo power amp, you also can look for some multi-channel power amp to save space. Using four of the channels and leave one channel unused on a 5channel power amp is perfectly ok.  
Music Reference RM-4 Input-Loading and Gain-Select plugs
I beleive you need to take off the top cover of your Music Reference RM-4 pre-preamp and look inside if the gain plug is 30dB, if it is 30dB then you should connect the RM-4 outputs to phono stage MM input, because most MM input of a phono stage ...

Making phono resistance plugs
@lalitk  What else I can do to achieve some consistency in load settings? Or is that simply not possible with my current phonostage? Please read the post from @tvad , set load to 47kΩ on your phono stage, use a rca Y adaptor and custom loading p... 
step up 220 voltage converter for Line Magnetic amp
Seems like he had bad experience with audio gears that made in China  
step up 220 voltage converter for Line Magnetic amp
Better still, what I would do, Raven integrated. Why anyone still buys anything from China is beyond me at this point. Does Raven Audio has any 845 integrated? and what made you think that OP is buying the used Line Magnetic 845 integrated amp fr...

Help connecting my AMPS to my ML Sequel II's
Do you still have all the cables? If there two pair of speaker cables, probably the Martin Logan was passive bi-amped. 
How do you feel about a wheeled dolly permanently under large floorstanding speakers?
I have wondered for years why no company has engineered this solution yet. You design an adjustable platform that has wheels that activate with a foot push fulcrum. You wheel into place then deactivate the wheels up and out of the way to then have... 
The secret to a great amplifier...
Any minute now Jack Nicholson will get up and scream, "You can't handle the truth". A Eaton Bussmann 10A/250V fast acting fuse typical dc resistance =0.008Ω and a typical power relay contact resistance = 0.1Ω !  
The secret to a great amplifier...
That fuse isn't even close to the most limiting part of the power pathway. I wish fuse can work as a inrush current limiter, so I don't need soft start circuitry in my amp. 
Is there anyone out there who has expert knowledge of upc1237 ?
I’m not an expert, but I think those upc1237 currently available in the market are come from Taiwan, according to their data sheet, the absolute max Vcc rating is 60V. Maybe drop the voltage to 25 to 45V using zener diodes is a safer way to go. ht...
