Things were a more than a little mixed up over here with hurricane Sandy showing us how fragile our modern way of life really is.

Was out of work due to lack of commercially supplied power for a couple of weeks so I decided to play around with some of the equipment I've collected over the years.
Some of you might know that I "rescued" a Fisher 500c receiver a few years ago.

Quite literally kicked to the curb with the trash, with a new set of output tubes, and some replacement caps the unit fired up like the day it left the factory! To complete the analog setup I purchased a vintage Marantz TT with a Sure V15 type IV cart.
Ran that setup in the office rig driving a set of 1997 vintage JMLabs Micron Carats. Smooth and warm was the sound, with the slightly rolled off tubes complimenting the reach for the sky high Tioxid inverted dome tweeter of the Carats. Still, I only ever considered it a mid-fi rig.
So with a lot more time on my hands, and a generator wasting gas just powering light bulbs. I moved the Marantz turntable into the main rig. Actually I moved a bunch of things around. My PS Audio Classic 250 amp is somewhat sensitive to power fluctuations. Back in the summer we had a couple of days with low voltage and the unit wouldn't run at all! In addition the unit is a bit of a collectors piece so I didn't want to expose it to any possible generator power spike. With that being said I was getting real tired of not listening to my main rig!
A couple of years ago I picked up a slightly used Ming Da MC34-ab. http://www.polkaudio.com/forums/attachment.php?attachmentid=25134&stc=1&d=1180058484
The original owner had replaced the entire tube compliment with NOS tubes in the front end, and a set of upgraded JJ E34L output tubes. Nominally rated at 75wpc, this amp sounds just as powerful as my old 150wpc PS Audio HCA-2, easily driving my Magnepan 3.6's to realistic SPL's. When I got it I had used the mc34-ab as a stand alone integrated for a while, and while I did enjoy it, when the Classic 250 came on board the Ming Da got the boot. Now that I needed an amp I put the Ming Da back into service, this time though as a straight power amp, bypassing the internal switching circuitry.
So here I am expecting the MC34-ab to sound like it did over a year ago, which was good, but nothing to write home about. Imagine my surprise to find that it was a different animal! Maybe my year with a zero flat reference amp had left me wanting something with a little more personality, but I wasn't expecting this. Driving this tube amp with a pre seems to have changed it's character from an common blended red to a vintage Cabernet. While the most used word for describing tube amps is "warm" the best description for this rig now is "warm and spicy!"
The best was yet to come though, as I had only ever run the TT in the "warm and chewy" Fisher 500c rig. Now hooked into the main rig the TT is a whole new animal. Air, focus, startling dynamics, spooky floating vocalists that I had associated with only the best of my CD's all there. All this with a mid-fi TT? Why didn't I do this earlier?!
Of course now I have to see where this is all going, so I'm on the hunt for a killer TT rig that won't break the budget.
