Class D Technology
Kijanki 11-21-2016One can argue that this phase delay might be beneficial since many speakers have positive phase shift at these frequencies.  I don't have data for my speakers, but I picked one of the speakers reviewed by Stereophile.  As you... 
Class D Technology
Also what is the math relationship between bandwidth and phase shift? Where does 10X bandwidth number come from? Hi Mapman,If I'm not mistaken class D amplifiers typically use an output filter consisting of a series inductor and a shunt capacit... 
Listen...chair
I’ve been happy using Wassily Chairs my wife and I purchased back in the 1970s. And I would expect any effects they might have on sonics to be very minimal compared to most other kinds of chairs. Various knockoffs are available at much lower price... 
Can I convert stereo to mono for a phono input
Is switching the leads to one channel on the cartridge the same as me attaching a multimeter to the center pin on one channel and the ground sleeve on the other? Or is the ground blended by the phono preamp? Hi Peter,While I suppose there may be a... 
XLR to RCA interconnect. Does mixed connectors provide less noise compared RCA to RCA?
One reason to go TO an XLR at the amp is when the XLR inputs have greater impedance than the RCA equivalents, often XLR inputs are double. Usually, although not always, the reason for the doubled impedance on XLR interfaces (inputs or outputs) com... 
Your Go to CD to Impress

XLR to RCA interconnect. Does mixed connectors provide less noise compared RCA to RCA?
A follow-up to my previous post: I took a look at the manual for the CDP. It states: It is not normally recommended to use both sets of analog outputs simultaneously. Also, Stereophile’s measurements of an earlier version of the player show output... 
XLR to RCA interconnect. Does mixed connectors provide less noise compared RCA to RCA?
Hi Jim,I’d suggest asking Ayre, as I suspect the most significant factor that would be involved is how the balanced and unbalanced output circuits of the CDP are implemented. But FWIW my guess is that changing to an XLR-to-RCA cable is unlikely to... 
Looking for laptop Windows 10 for music only.
Hi John,First, as you undoubtedly realize the answers to most questions regarding configuration of a computer for audio applications figures to be dependent on the specific computer, the specific DAC that is being used, and the specific system, an... 
Hi-Fi Tunig Fuses & Parasound A21
Geoff, note that he said "reasonable explanations."First, as I have explained in detail in various fuse-related threads here, measured differences that have been reported among various fuses are too small to account for the sonic benefits that hav... 
Line Magnetic 219ia vs Mc225
Jkull 11-19-2016 Mids are where it counts most if I am left to chose. This was part of my issue with my outgoing setup. Lack of presence in the mids and an abundance of booming bass.An encouraging point related to that, for both the 508ia and t... 
Anything as " fast" as SPECTRAL gear?
Ptss, amplifier damping factor is usually specified based on the assumption that speaker impedance is 8 ohms. So:DF = (8 ohms)/(output impedance, expressed in ohms)and equivalently,Output impedance (expressed in ohms) = (8 ohms)/DFAs you can see, ... 
Line Magnetic 219ia vs Mc225
To clarify further, I’m not saying that the impedance variations of the Cornwall will "hinder the sound." Most speakers have significant impedance variations as a function of frequency, in varying ways and to varying degrees. I’m just saying that ... 
Line Magnetic 219ia vs Mc225
Jkull, yes, I recognize that. To be sure it’s clear, though, my previous post relates purely to the tonal and sonic characteristics that will result from the particular amp/speaker combination, not to noise or other "unattractive and avoidable add... 
Line Magnetic 219ia vs Mc225
One more point I would add relates to the impedance plot for the later version Cornwall II that is shown on page 12 (pdf page 14) of the paper I referenced in my previous post. It can be seen that the impedance varies from around 5 or 6 ohms in mu...
