Speaker efficiency vs. power requirements
Sorry Sean I did not mean to say that nobody can hear less than 3db differences. I meant to say that in the context of our discussion on amplifiers, a 3db difference and doubling amp power is barely discernible as hearing a loudness difference in ... 
Speaker efficiency vs. power requirements
I DON'T KNOW WHO YOU WERE TALKING TO BUT BOY ARE THEY CONFUSED. Speaker sensitivity is simply the amount of db's produced as a reference (usually 1 watt at 1 meter). What your amp kicks out are electrical watts (you know the RMS variety) while wha... 
Amp Testing vs. speaker safety
Thanks Sean, just trying to avoid the hassle but I am more concerned with the safety of the equipment. 
The best way to shield components from each other?
My room width is similar to yours, and my solution is the easiest. Try the sub between your front speakers and in front of the TV. That's the way many theater set-ups do it. My sub fires to the front. Just put it about 3 or so feet in front of the... 
Tube reliability in amps
to blues man and the few last posters, I am not an audio novice. It's just that I am a tube novice. I know listening is top priority. It's just that I am not a tweaker. I don't want a lot of down time due to finicky tubes, long warm-ups etc. My li... 
Tube reliability in amps
hey newbie, instead of me calling up a whole lot of manufactuers, can you give me an idea of what is a lot or little bias on a tube, so I can hone in on the guys with longer life tube designs? 
Pre amp to sub hookup, or speaker level?
If you have stereo inputs and outputs on the sub, then do what I do. Simply run your main output to the sub input, then run the sub output to your main amp input. This will give you extra dynamic range. 
Pre amp to sub hookup, or speaker level?
What kind of inputs and outputs does your sub have? A high level connection uses the speaker wires, a low level connection uses the RCA plugs into your amp. Need some more info for a proper answer. 
How could surround sound be used in an audiophile system?
To redwoodgarden, here's what I do. get a cheap DD surround processor (Onkyo, Sony or other Japanese). run your 5 channels from the processor to your amps. Now if you have a passive box, run your front speakers into the amp and connect with monste... 
Amazing Solo Piano Recordings
Don't know if it was mentioned or still available but there was a recording on Conisseur (know it's spelled wrong) Society with a pianist named Banderas of Chopin Scherzos. One of the best ever made & worth searching for. 
Best amp for B&W Nautilus 804? Looking for advice.
I too would like some help. I have a pair of Matrix 804's. I have been in the market for a new power amp. Presently I am using a Carver 705x (125 wpc) 5 channel as a power amp with an AI3 pre-amp. I tried the Transcendent compact 150 wpc and did n... 
Thoughts from the Dark Side (ABX)
I come from a slightly different perspective. I have recently (8 years ago) come from the other side. I am a subjectivist but there is a difference between a subj... reviewer and a subj...listener. As a listener I have no problem with abx tests fo... 
Have Hiss-Need Help ASAP
Have you tried putting in a different or cheaper pair of speakers? With multiple amp and preamp changes it can't be them. Also how loud is the hiss and does it change (as it should) with phono and high (CD) outputs? Almost all systems will hiss at... 
Hate to ask......
I'm another one in the home theater/stereo camp. I also don't worry about switching my lights on and off for the ultimate sound. I'm not a tweaker, however I do listen to my speakers in the audiophile approved way with the grills off. However I al... 
Which 5 ch Amp for Home Theater?
I have a carver 705 x 5 channel 125 watt amp. It was reviewed in SGHT. It is worth looking for used. New it was only about $1200-1500. It has great bass and a nice top end. Sounds better than a lot of $2000+ audiophile amps that I have heard. By t...
