Is listening daily at an average of 85db safe?
Nemesis,What matters is the peaks that make up the average level. I suspect the levels you use are OK. I assume you know dB(C) is spectrally pretty flat, whereas dB(A) reflects auditory sensitivity. I don't understand what 6550c may have read. Aco... 
Oppo BDP 83SE- RESULTS ARE IN
Longhornguy,I reread my post and was unable to locate a double negative. You may have been mislead by "there is no unambiguous comparison" in which no and un are in juxtaposition, but that doesn't constitute no double negative. That last phrase, h... 
Oppo BDP 83SE- RESULTS ARE IN
Bacardi,As I understand your reply, there is no unambiguous comparison of HDMI v analog, and any such comparison seems difficult to make in your setup. Thus concluding that HDMI is inferior to analog in the general case is not possible.db 
integra dtr 80.1
I haven't gotten a clear read on the "wonderful audio" aspect, and wish I knew the answer. I tried to audition a 80.1 with stereo CDs and SACDS with which I'm very familiar. The setup in the private home was less than ideal, so I couldn't conclude... 
Oppo BDP 83SE- RESULTS ARE IN
Bacardi,As I understand your post it seems you've confounded replacing equipment with switching from HDMI to analog, and concluded HDMI is inferior to analog. Could it be that a new Oppo BDP 83SE is an improvement over an early PS3 and an Onkyo SC... 
The pursuit of bass...
Jax2 asked: What is the difference between pink noise and white noise (noticed the recommendation for white noise in the Geddes reference)?IIRC, white noise has equal SPL/Hz across the spectrum, whereas pink noise has equal SPL in each octave band... 
Projector
Shadorne,I think of you mostly as an audio guy, but thanks for reviving this thread. Several years ago, I bought a used Sony VPL-50 (Pearl) projector; it's native resolution is 1080p. Our carpenter built a 100" 1.3 screen using commercially availa... 
Are projector screens transparent to sound?
I realize this is a bit off topic, but several of the replies here suggest relevant expertise.I use my system for both HT and music. Would covering the 100" screen with velvet drapes when not viewing improve depth of 2.1 imaging? The LRC speaker f... 
D2v vs Classe ssp800, which would you prefer?
Docrobbi,In the latest Stereophile issue, Kal Rubinson writes concerning the Class'e CT-SSP "There is also the option of applying room/speaker equalization with a very effective parametric EQ, but no tools for setting this." Unfortunately, Rubinso... 
D2v vs Classe ssp800, which would you prefer?
What about the new Classe' processor Kal Rubinson raves about in the latest issue of Stereophile? It's just a bit more than the SSP 800, and looks less self-consciously stylish. I haven't heard either the D2v or SSP 800, but the local dealer who h... 
VTI audio rack, any good?
I have a couple of four-shelf VTI racks and a two-shelf rack filled with sand and with rather expensive custom made spikes separating each layer of shelves. The racks have served well and represent good value. The spikes can be unscrewed and used ... 
Problems with room acoustics??
Thanks for the link, Rodman. I ordered a set. Auralex SubDudes have worked well for me.db 
The Hub: Acoustic Research - third in a series
My system for many years was comprised of an AR turntable with a Shure V15-II cartridge, a Marantz Model 18 receiver, and a pair of AR-3a speakers. I still have all of these, and hope to set them up in a vintage system someday. Incidentally, Pgulr... 
The Hub: History of Dynaco part 1
After having built a Heathkit amp and tuner, I built several Dynaco Mk IIIs, and they were easy. The PAM-1, though, was a maze of wires. I finished it, but it was a mess and produced more anxiety for me than any final exam.db
