Great info, thanks B-Man! For #3, I thought I read somewhere that the amp's power supply feeds noise back into the AC line. I'm curious if anyone added a 12V trigger relay inside one of these amps.

Ok a few more questions. I returned the furman power conditioner. I didn't like that it was always on. If I powered it off, the TV and cable box were upset when they were powered back up again. To the questions: 1. I think I only have 15amps available at this power outlet. Am I going to run into any power problems? If so, any suggestions. I do not want to rewire the house. I also plan to purchase some 400-700 watt class D driven12-15" subs at some point. First location preference is outboard sides of speakers on the floor. 2. Someone mentioned the M-4.0T can trash speakers. Is this a reference to sheer power or that it can fail and burn up the speakers? If its a failure mode, what can I do to protect my system? Run inline 4-6Amp fuses on the speaker wire? 3. Power conditioning and amp turn on/turn off. What are some suggestions to isolate the Carver Amp noise AND have a solution to auto power on/off with the receiver? I'm not looking to spend $500 on another box. I am up for DIY projects and/or buying something off the shelf. Receiver has 12v trigger out. I started reviewing the "power" threads in the site here and see some good info. I also just e-bayed a used Hakko soldering iron because my current one is junk. Thanks, Billy

Ok, here is an attempt at a picture. I took this while I was still assembling everything. The small bookshelves are my presence speakers. I'm still messing around with their location. The funny paintings were a wine event with my wife. The blue box is a RCA to XLR convertor that I was trying out with the Crown XLS amps. Gonna e-bay it now that I returned them. So far, it looks like a 65" TV will fit perfect on the stand edge to edge. The 46 is pretty old now. The Carver amp(s) will go on the left side. When I take the glass door off, it fits 19" rack mount gear perfect. There is a line conditioner on the bottom. I'll probably cut some holes in the back for vents and possibly add 12v or 5v fans depending on heat.

I need to figure out how to post a picture. The easy way seems to only want small pictures.

Hi all, thanks for the welcome! I can work on simple electronics and can learn pretty quick. I don't have an oscilloscope but I do have a Fluke 87. I recently got back into audio gear. Wife flipped out when a pallet of 2 tower speakers arrived by truck. It was quite amusing. Boxes are still piled up in the guest bedroom. Equipment: Yamaha RX-A2030 - ESS DAC's do surprisingly well with Pandora stream, YPAO actually works well. Furman rack mount filter - PL Plus C Sony Blue Ray BDP-S550 Sony XBR46" TV (probably upgrade soon) Polk RTi12 (driven surprising well from Yamaha but bought the amp for these) - 50" tall Aperion Audio Verus Grand bookshelf (Front Presence L/R), Verus Forte center No rear channels right now, nowhere to place in the room due to odd shape. Martin Logan sub 8" - need better sub. Looking at SVS, Rythmik, HSU, probably end up with "small" sealed 15(s) Waiting for M-4.0t that is claimed perfect condition....we'll see. Returned Crown XLS1500 amps x 2 due to hissing & humming, lost bass clarity at high volume. Were ran in 8ohm mono at 1040watts each claimed; barely hit -10db lights. Would draw enough power from wall socket to shut down receiver or possibly overloaded RCA output. Never tripped breaker. Apple TV requires higher min voltage and would shut off first before receiver shut off. They sucked in my system. without RCA connected, still hissed, although way less. I could hear it from 10 feet away. Music Types and examples: Old Rock: Stones, Zeppelin, Dire Straits, Elton John, Doors, Cars, Pixies, Police, Pink Floyd, War, Smashing Pumpkins, U2 New Rock/Pop: Black Eyed Peas, Flight Facilities, Adventure Club, Zeds Dead, Lounge: Paris Combo, Gotan Project, Stephane Pompougnac Club/Electro: Kaskade, Deadmau5, Tiesto About 15 years ago, I used to have a Hafler XL280, Carver preamp, some 16" woofer speakers with mid and tweeters on fronts and tops, can't remember brand. It blasted pretty loud and clear for hand me down 2 channel gear. I sold it to the business I worked for which used it in a 60000 square foot CNC manufacturing facility. It was loud enough to hear with ear protection on while 5 CNC mills and 2 CNC lathes ran. I figured it was time to get a real system again.

I just purchased a M-4.0T that appears to be in good condition from FleaBay. It won't arrive for a week or so but I thought I should find a place where I can get to know it better. I'm looking forward to reading up on all the info here and may have a few questions for the members! Billy
