Yes, the topic has been covered. Bi-amping does not double the power going into the speakers. Mass market AVRs are not good candidates for use in bi-amping. While each channel of an AVR is capable...

Step-down transformers, even ones rated up to several kilowatts, are not expensive. One that is 2-3 times the maximum power consumption of the amp and other equipment you are running should work...

Looking at internal shots of the Emo amps, I agree with others that their layout is not mod-friendly. You have connectors soldered to the pre-driver board, and construction that involves a lot of...

If the original RCA jacks are attached directly to a PC board, they could have developed a bad connection. In either case, for peace of mind I would replace the existing ones with new, better...

Noise pickup has no bearing on wire quality.

You may have better luck asking your question in the car audio section. Regarding engine noise through your speakers, it sounds like you need to install an engine noise filter. I am not a car/truck...

+1 bleeder resistor.

Agree on selling on eBay "as is for parts not working".

The C-70 alone is worth around $180.00. The Yamaha preamps are legendary for their excellent phono stage, and I think you will be impressed no matter how your TT is hooked up. The direct phono...

It seems like you should consult a professional A/V installer who would have the expertise and access to the right equipment to install a whole house/in-wall music setup. Are you up to the task of...

I concur.

Some people obviously benefit from bi-wiring and bi-amping or high end speaker manufacturers would not make their speakers with split crossovers. IMO a good reason to bi-amp would be to take...

Was that the Live from The Beacon Theater, New York concert ? Amazing performance. I've got the DVD and CD.

Yes, that will work. I've done it more than once.

You should have no problem connecting a Marantz or any other brand receiver to a speaker or switchbox with a common ground. It is only amplifiers that are natively of bridged design or stereo amps...

It is my strong suspicion that the M504's output remains at about the same regardless of the load. The manufacturer does not list outputs at less than 8 ohms. Output specs at 20Hz - 20KHz and 1kHz...

The M-504 service manual does not even list output into 4 ohms. IMO, no the M-504 is not a "high current" amp, if you use doubling of power when output impedance is halved as criteria for making...

You did not say how large your outdoor space is, but if its of substantial size, I would go with a good quality passive pro sub, driven by an external amp, along with mono EQ from the receiver's sub...

That a nice receiver you have. I'm running an older Marantz SR-19 in my HT system. Its a big heavy unit, with completely separate preamp outs/amp ins for all channels. I am hardpressed to hear a...

Ditto what face said. I use the balanced outputs of my Marantz SACD player, but my preamp and amp are true differential from input to output, so I run my system all balanced.

Three foot runs of speaker cable are too short. You will be forced to place your speakers too close together, and performance will suffer. You could get away with 6-foot pairs. There should be no...

What you experienced was typical of audio shows. Don't go expecting systems to be "cranked". Too loud and it would mean disturbing other exhibitors. The setups are meant to give you a little...
