| How to diagnose the need for room treatment? In the bass, the arrival/decay times are more easily measured and corrected whereas at higher frequencies room mode interactions approach randomness. Thus, at those higher frequencies, only FR adjustments are feasible.Yes, at higher frequencies o... | |
| Resistive vs capacitive loading See the following:http://www.hagtech.com/loading.htmlThe bottom line: For a low output mc, proper resistive loading is much more important than capacitive loading.And yes, those phono preamps that provide adjustable input loading will typically pr... | |
| Mono Problem? Sure sounds like one channel is wired out of phase (hot and ground interchanged), even though you checked the connections carefully. Maybe the cartridge itself is miswired, or its color-coding is misleading. What happens if you listen to a stereo ... | |
| How to diagnose the need for room treatment? Although I don't have the room optimization experience that most of the others have had, I'd like to offer one small but I think significant point.Particularly once you get above bass frequencies, tuning the room for flat frequency response using ... | |
| How to eliminate FM RF coming thru turntable? Are you really sure that it is an FM station you are hearing? There are two things that seem to point to AM -- the fact that it is being demodulated into understandable audio, as discussed above; and the fact that the problem occurs only at night.... | |
| Running dedicated AC mains .... need advice .... I provided the link to show what can happen if the equipment ground for a branch circuit was connected to an earth ground electrode ONLY.[emphasis added]Yes, I agree completely, that would be a definite no-no. Thanks for the good references!Regard... | |
| How make my Ayre system "warmer"? Tubes don't add distortion until they are driven to distortion. Then they produce even-order harmonics rather than the odd-order harmonics that SS devices produce when over-driven. Then why, to cite what I admit is probably a somewhat extreme exam... | |
| cdp soundstage Just to make sure that what I said about absolute phase is clear, I was not referring to the connections being wrong. Reversing the plus and minus of one channel to the speakers, for instance, would mean that RELATIVE phase is incorrect (relative ... | |
| cdp soundstage That's odd since CDs have a MUCH greater signal to noise ratio.As well as much greater channel separation, of course.I recorded from lp onto disc and the soundstage shrank big time.What was doing the A/D conversion? Quality A/D conversion is techn... | |
| How to eliminate FM RF coming thru turntable? A corrosion-formed diode can indeed rectify an AM station's signal so as to produce recognizable audio. In my experience what you usually get is a mixture of several stations, some louder than others.However, it takes a lot more than a diode to pi... | |
| How to eliminate FM RF coming thru turntable? Quoting from a response I made a while back when someone else had a similar problem:I believe that oxidized or dirty contacts can cause that, particularly as here where low level signals are involved that are subsequently subject to high gain. The... | |
| How make my Ayre system "warmer"? I am pretty much in agreement with the preceding comments about warmth. But I would add that lack of "warmth" (or what the original poster describes as sound that is a bit too "lean" or "clean), could also be thought of as lacking in what I would ... | |
| How make my Ayre system "warmer"? That's some really fine equipment you have there, Tje. But perhaps most or all of it is too consistently in the direction of being analytical, revealing, and neutral. Overall, perhaps too much of a good thing.Along the lines of what some of the ot... | |
| AC Power Cord Wire Gauge Nsgarch,I take no position on your findings that "the effect of using larger (and larger!) gauge conductors is the same, regardless of the brand or topology of the cord." I have no reason to doubt that your sonic perceptions were accurate, althoug... | |
| AC Power Cord Wire Gauge The age-old question, "Why make PC's any bigger gauge than what's in the wall?" has a very simple answer: 'energy transfer' I'll explain:When you plug your whatever into a wall receptacle, you are basically hooking it up (in parallel with other de... |
