The first problem of speakers randomly working, and kick in with turning up the volume is dirty contacts in the relay. Sometimes new relays don't fit the space allowed for the existing relay or the pin locations don't line up with the board. The existing relay can be removed, dis-assembled, clean th...

You have to try them for yourself and buy what you like the sound of. When a stylus is placed on a record without the platter even turning, the pressure on the 2 contact points is in the neighbourhood of 35,000 psi. This is simply because the 2 contact points are microscopic. When the platter is rot...

AKG has made some great headphones over the years, a classic and favourite of mine was the K240.

My first thought would be that either your cartridge is not aligned properly, worn out or possible a bad choice with the Rega arm. I'm not familiar with Rega arms but I'm sure others here could offer more insight. The PP2 has both MM and MC settings. Have you checked to make sure the switch never g...

Do you have a subwoofer and is the sub turned on in the Nad's speaker settings?

That kicks serious BUTTTTTT. Wow. I love the original, but that was astounding. Thanks for that :D I think it is so cool that Joe brings such great classics forward. He and Beth Hart kick butt too. This is kinda long, but she is the Joplin of our times. IMHO https://www.youtube.com/watch?v=UEHwO_UE...

(a) Try having a really close look at the entire lengths of your speaker cables. You could also test them for a short circuit while bending and manipulating them. If they are inexpensive, maybe just replace them. I cooked an amp due to a concealed short in a speaker wire. (b) Use one of these polar...

resilient metal channel between the joists (or studs) and the drywall does as much or more as any other product or material. it slows the transmission of sound thru solid wood by decoupling the framing from the finish material. inexpensive to purchase and not much work to install. run perpendicular...

it immediately fries the fuse. I opened the amp module to find what I thought was a leaky cap. Brown crusty stuff all over a couple caps and a small coil. Not wet though. Flaked the stuff off ,now I'm not sure if it wasn't just some glue or damping compound misplaced. need a guy with a schematic an...

One of the dangers of 1st order xovers for the tweeter is not filtering out enough of the frequency range below the actual xover point of the tweeter, can be pretty hard on tweeters. I get the desire for the simpler design and fewer components but you might go through a few tweeters.

I have a Scott 222C in very nice cosmetic condition but it hasn't been used for many years. Is it a piece worth having a tech go through or is it a mediocre sounding integrated that I should sell? I remember those as great sounding, not sure if that's the same model I was thinking of but in general...

Those are both very old cartridges but great sounding. I still run a VMS20 on an old Dual 1228 idler and it is very nice. Similar to the OM or LM20 (which I also owns), I believe the tip is nude. VMS is a thirty plus year old design and replacements are mostly NOS, although aftermarket is available...

Many times over the years I've had a customer that needed 20 or 25' of cable and were using high end cables on a good system. Then they had moved, changed the system layout and only needed 10 or 12'. They would ask me if it was worth shortening them. I had always said, if you can shorten that much ...

You can remove the module and send it to Plurison who was the Canadian distributor. http://www.plurison.com
Call ahead and arrange it.

And then you start talking about all these measurements and wavelengths. Honestly, you should have stopped at 'I don't care'.[/quote]

It's just basic information to help anyone with any system improve the sound at no cost.
