| Speaker noise - hissing One other question & suggestion. Is the noise equal between channels? While small signal tubes are often the source of hissing (aka white noise) and can increase as tubes age, it is unlikely that all four of the 6SN7 tubes are deteriorating at... | |
| Speaker noise - hissing More info is needed.What make and model for the amp? How old is it? Has it been serviced lately? How many hours are on the tubes? Does the hiss occur when only the amp is on and no sources are connected? Same with the speakers. If the speakers are... | |
| Anyone on The Waifs? "Up All Night" was my intro album to The Waifs. They are a wonderful indy group out of Australia. I believe I have all their albums and this is the one I'd suggest next. The "London Still" cut is just wonderful. They are a great group and the reco... | |
| New Woofers for Alon V's? It sounds like the woofers have fairly standard foam surrounds. There are several places where you can buy new surrounds with instructions on how to replace. The new parts for last pair I did for a friend cost $30 delivered.There are also many peo... | |
| Tube amplifier bad caps Just a quick observation that bad caps don't necessarily have a visible external leak. I've seen plenty of way out-of-spec ones that appear physically fine. Do you have a voltage meter? Do you have a schematic that indicates voltages at various te... | |
| Tube amplifier bad caps If you are convinced it is caps, the larger ones are the more likely candidates. However, you are going to have to remove the circuit board to get to them as there is likely a solder connection on the other side of the board. That means moving and... | |
| replace a full Cello System? I agree with Shadorne - there is something about this situation that doesn't add up. Anyone who had personally selected this gear for their own musical pleasure would not be asking a family friend for replacement suggestions. They'd be out selecti... | |
| Any audiophile who is on blood pressure medication >> I hear once you start taking blood pressure meds, you're on them for life, That is not true. I spent close to 10 years on them. About two years ago they cut the dose in half and about six months ago I was taken off them completely. I had ... | |
| Background noise problems The reports I found gave the same voltage gain (30 dB) for both the DNA-125 and the DNA-225. It will be interesting to see what you eventually find. | |
| Background noise problems It almost sounds like the McCormack has some type of auto-sensing gain control, but their web site and the reviews mention nothing about that. The noise doesn't really behave like any defect I've seen before, but maybe that's what is going on. Onl... | |
| Background noise problems Just had another thought. Why don't you call the power amp manufacturer and see if there is a simple mod to reduce the input sensitivity of the McCormack? This would reduce the amp's gain and reduce the hiss. You'd have to run the preamp's volume ... | |
| FLAC or Windows Lossless for music archive? The one problem I have with MS Windows formats is they have a bad habit of changing things on you. (Look at how many times they've changed the file format for *.DOC and *.XLS files over the years.) FLAC is an open-source file format and as such I ... | |
| Any audiophile who is on blood pressure medication It can sometimes take several weeks to a month or two for the body to adjust to a new medication such as those for blood pressure. If you don't find yourself getting back to normal after that period, you should then talk to your doctor. He or she ... | |
| Background noise problems Actually, 80 dB for the Herron is a pretty good noise figure (just reading from their spec sheet). That was for the moving coil input option and that circuit has a lot of gain. I would think that figure would improve with a line level input. And a... | |
| Background noise problems The specs on the McCormack show a 98 dB S/N ratio with a 1 volt input sensitivity for full output. The Herron has an 80 dB S/N ratio (for moving coil input) and the speakers show a sensitivity of 92 dB.The rushing noise you hear is white noise and... |
