How could you possibly post your experiences about a DAC? There are so many other contributing factors such as layout, power supply, integration, components used, etc in the product they go into that determines the overall fidelity of the system. Now that being said, I would have to give the...

Amps typically don't run up to their rail voltages b/c of drop off characteristics of the transistors, though you can get close if you use good enough ones. When you see the Cap V rating, its usually good design practice to keep your rails 10-15% lower than their rated values. Hence an 80VV...

hggns; Your estimates for 7 speakers at 88dB sensitivity driven with 17 watts seems pretty accurate (not factoring in room gain which can be much higher than you anticipate) Use this calculator as a swag: http://www.myhometheater.homestead.com/splcalculator.html If you place the...

Sound Reinforcement is an entirely different animal. They use multiple large high efficient, controlled dispersion horn arrays with very powerful and high efficient switching amps. The end result is HUGE SPL with fidelity NOT being a primary concern.

B/C the amps power supply would have to way about 200lbs and if it ever managed to deliver full power to any particular speaker, it would instantly melt the voice coils.

If you hooked up your receiver to that outlet, it will quickly become your stove if you turn the volume up high enough and use forks as your speaker loads :D

As I said in my last post, some receivers have amp assignability so you can reroute them to biamp. SPK A/B are the same connection point either in series or parallel to each other from the same channels.

This is bad advice for someone doing home theater, especially if you are using a processor that truncates the LFE channel when setting the crossover below 80Hz. A better solution would be to place 2 small subs in the room and follow our subwoofer placement guidelines. While square rooms aren't...

I've seen the posts from Simple Mind, I mean Simple Theater :rolleyes: Just goes to show you that the people who know the least amount about such topics, are often the most vocal.

Oh my! All you did was Biwire NOT Biamp. Speaker A/B terminals are either wired in series or parallel to the same amp. If you wish to biamp, you must use 4 amps in the receiver, many of which today allow you to reassign to the front channels for biamping.

Back in my college days working at a high end dealer, I can tell you the Mac speakers from yesteryear were very good indeed.

What is even funnier is any cable can pass this test if you terminate it to its characteristic impedance :rolleyes:

What a load of crap and typical attitude of an audio elitist who thinks you require exotic equipment to drive a pair of speakers. If that was the case. then its more an issue with poor speaker design, NOT poor electronics. Rotel makes good amplifiers, certainly good enough to drive a wide...

No a good amp is still a necessity. We don't listen to continuous test tones and its important to realize that. An amp should have plenty of headroom to hit peaks undistorted while at the same time have a low enough output impedance to minimize frequency response variations when driving a...

Their literature is a load of crapola. I suggest reading this excellent article Rod Elliot authored that covers this very topic. Cable Impedance No cable will pass a high frequency squarewave properly unless it is terminated with the correct impedance at both ends, and the 'proof' that...

I was not "offended" but understood.

All; I am currently reviewing a 5CH linear Class G amp and pulled some efficiency #'s for your enjoyment. Class G amps are typically more efficient than a/b. These tests were conducted using regulation from the APC S15. Amps were testing to no more than 0.1% THD + N. Test tone was a...

THX we fixed it.

Um No. Unless the amp itself has a power supply big enough to sink that much power, its not gonna work. Why do you feel you need that much power and why do you think all channels simultaneously will need it? A single 90dB SPL @ 1 watt/meter speaker playing 10 watts will generate 100dB SPL...

When doing power load estimates for home wiring, you DON"T assume all outlets are operating at full capacity just like you don't assume all channels will be driven at full capacity on a multichannel amplifier. My advice is to run a dedicated line or 2 to your home theater equipment, especially...
