Thoughts on a Marantz MM9000 amp for a 4 Ohm ...
Dynaudio's require gobs of power to perform at their best. While your amp may be able to drive them to very reasonable listening levels, your speakers will not be doing what they are capable of providing until you can provide them with both a high... 
High efficiency speakers vs Low, pros and cons
Speakers that are high efficiency ( 95 - 96 dB's and up ) tend to sound punchier aka "more dynamic". This is even truer for "ultra high efficiency" designs ( 100+ dB's ). Having said that, most of them also tend to be bandwidth limited and lack th... 
Can I run my Amp from a Line Conditioner?
To put things into perspective, your amp alone can EASILY pull 20+ amps by itself if you are throttling the volume control. You have to remember that this amp is FIVE x 200 wpc @ 8 ohms or FIVE x 400 wpc @ 4 ohms. A review i have of the standard (... 
Newbie que on "recommended amplifier" rating
Since we are on this subject, how much power can a pair of Bose 901's handle ? I think that, ever since the Series IV, Bose has stated "unlimited power handling capabilities". Is that because the 24 gauge wiring inside the cabinets limits power tr... 
Front port vs. Rear Port
Port noise or "chuffing" has more to do with port shape and size than where it is mounted. While it is true that it would probably be more apparent on a front mounted design, it would still be taking place if the port was rear mounted. You just wo... 
Newbie que on "recommended amplifier" rating
"I believe you can never have 'clean' power." I think John meant to say " I believe you can never have TOO MUCH "clean" power." If that is the case, i agree wholeheartedly : )Honestly though, you are more likely to damage a speaker from "underdriv... 
Can I run my Amp from a Line Conditioner?
While i could tear the response from RGPC up on technical terms, i know that some folks have & use these with good results. I do not doubt that they offer some form of help in specific situations, but i do severely doubt some of the claims tha... 
My question is about bi or triamping.
Active multi-amping is quite common for pro sound reinforcement but is a bit of an oddity when it comes to home audio. As such, manufacturers build products for the market that buys them the most. Having said that, Phil Marchand markets kits that ... 
Have you ever done outboarding?
If you go the separate Power Supply / Amp route, i would suggest leaving at least the caps in the amplifier box. This allows the circuitry to pull from the caps as needed rather than have to draw all the way back from the power supply box and all ... 
AR ES–1 Problem.... Suggestions
Very helpful post Viridian. Sean> 
Sunfire Subwoofer Installation help needed
Zenieth: Once you can get the sub dialed in ( patience and experimentation are worth their weight in gold here ), you might want to think about an aftermarket power cord for at least your CD player. I purchased a GCD-750 locally for a friend that ... 
Speakers room positioning - diff tricks ?
I didn't look for the thread that Newbee mentioned, but this sounds a lot like the Audio Physic method of speaker placement. You might try their website to see if they still have this approach available for viewing. Sean> 
Am I underpowering my Magnepan 3.6's?
You can't have enough power for speakers like this. While quantity is important and more is better in terms of "watts", quality counts too. Sean 
Pro or hi-fi amp, which one would you choose?
Cdc: I was not so much talking about active speakers as i was active bi / tri / quad amplification i.e. no passive crossovers between amp and speaker drivers. While i do think that active speakers could offer benefits in the fact that specific ( c... 
Pro or hi-fi amp, which one would you choose?
Highend64: An amplifier that is bandwidth limited to just above 20 KHz will show "rounding" of the leading edge of a square wave at appr 2 KHz. That is a distortion as far as i'm concerned as it is not replicating the input signal. Passing a sine ...
