Phono stage matching - how critical
I think it's very critical. Two points to keep in mind...the cartridge has to like what it "sees" at the phono stage input, and the phono stage output has to be compatible with the line stage input. The first point is most critical, input impedanc... 
Benefit of low output moving-iron Grado ?
I have both Grado Sonata's, the 5mv and the .5mv versions. Same year even. I prefer the low output version hands down. So do all of my friends. The only hitch is you need a fairly high gain preamp to enjoy it. The 0.5mv version is quieter, more dy... 
Tube rolling 12AX7As
Look at the block diagram:http://www.mcintoshlabs.com/McintoshDocumentMaster/us/c2300om04.pdfFirst off, there is a difference between 12ax7 and 12ax7A"The published difference is that the 12AX7A can be used with heater circuits wired in parallel a... 
Golden Tube Audio SE-40 bias problem
This is a dumb question, but is the SE40 new to you and is this the first time you've tried to set the bias?I had to ask because the diagram of the molex bias connector in the owners manual is confusing. Looking at the diagram, you can't tell if i...

Coputer or NAS
Western Digital has one and two drive NAS unit's available. I would of course recommend the two drive unit set up RAID 1 (mirror). The drives are user replaceable, so if one drive in a mirror fails, you can replace it with a standard SATA drive an... 
Coputer or NAS
NAS stands for Network Aware Server. It is a hard drive that connects to your network through the router, just like a network printer. In the same manner that every computer on your "home network" or INTRA-Net can print to one Network Printer, tho... 
Grado Sonata1 Ref Vs. Audio Technica AT33EV
I have both the Sonata 1 Statement and the Sonata 1 reference and prefer the lower output model. Of course, you need a lot of gain to use it, but it's in a different league than it's high output brother.It is however very, very sensitive with rega... 
Adjust resistance & capacitance to
Need a little more info.Same cartridge, same turntable, same phono preamp, same line stage but different power amps? Or is itSame cartridge, same turntable, same phono preamp, different integrated amps?I'm asking this because I had a situation in ... 
Building an audio room - 12x22 - electrical plan?
You'll probably need Arc Fault Circuit Interrupter breakers for each circuit.http://en.wikipedia.org/wiki/Arc-fault_circuit_interrupter 
Which components to isolate
I think amplifiers draw the most current and the amount varies by demand. I think digital devices are noisier, broadcasting artifacts as they rapidly switch on and off. I'm basing this opinion on ground noise. A nice way to picture ground current ...

Schubert,You're lucky you didn't break your back, not from the flight or landing, but from the muscle contraction.Having witnessed a nearby strike for myself, it's amazing that anyone could survive the amount of energy unleashed.There's a very int... 
Which components to isolate
"I have three dedicated duplexes and want to minimize distortions put back into the system."I'm assuming that by "three dedicated duplexes" you mean each of them is on it's own branch circuit from the main panel, each protected by it's own breaker... 
Lightning
Very impressive description, thank you. What else can I say, lightning struck while I was home. As the days passed I noticed more and more appliances had failed until I realized there was a common event. To collect from my insurance company each f... 
Lightning
I understand everything you have stated but I still think it falls short of explaining why the amplifier was damaged in such a specific manner. Absolutely nothing else connected to the stereo was electrically damaged in a similar manner. The only ...
