High Current Monoblocks
Peter_s, Ohms law is how an amp's amps would be calculated.If you know the impedance...and for the case of a simple calculation, it would be the DC resistance, you would use probably 8 ohms. Find out your amp's power supply voltage. This will usua... 
High Current Monoblocks
First, amps are almost ALL voltage amplifiers, not current.Also, imdepance may not represent the true 'load' of these, or any other speaker for that matter.Phase angle, the amount that current leads or lags voltage is what really determines the 'l... 
Blown fuse and its soldering to a PCB
Not all circuit boards are created equal. Glass/Epoxy boards that I have seen are kind of translucent light green will take more 'rework' than cheesy cheap boards. I have no idea what the cheapo boards are made of, but when cooked it charcoals nic... 
Does impedance matter?
Agreed on both points....But, nobody ever said it was supposed to be easy. Also, once you are accostumed to this presentation of phase/impedance it is fairly easily seen. Frequency data would be Very helpful. 
Does impedance matter?
Has anyone looked at the link to the Smith Chart....It is a VERY interesting way to view the impedance curve of a speaker VS phase angles, which is really a much better way to evaluate 'is it a good or bad load?'happy listening..... 
Does impedance matter?
Thanks, Bomb, you da' bomb! Yeah, speaker impedance is an over-rated spec...and not all that useful.As you can see from my Moniker, I am a Magfan...now for over 25 years. The ONLY plan I have is to upgrade my X-overs using all standard, but hi-end... 
what is the theory behind maple stands and racks?
Any fans of granite shelves?

Markphd, your Linn TT platter rings? That can't be good, especially if the music contains that frequency.I had a Dual many years ago with a 2 piece platter.....Each piece by itself would ring....nice sustain, too. But together they were pretty ine... 
what is the rule of thirds?
Enter 'room mode calculator' in google and enter golden ratio numbers and see that there are few bass nodes of note. As a starting point for an all-new room, this is a very good way to go. Or, even to produce a low-resonance speaker enclosure.Phi ... 
Mac / Airport Express question
Sorry, Pdreher, No can do! Just shot 2 years worth of 'optional' money on a new IMac.....the last (better be!) computer I'll ever need. My stereo had remained unchanged for about 20 years+, until late '07, I even still had my original / rebuilt@fa... 
Speaker cable options for Magnepan 1.6
10ga. belden, via Blue Jeans. Not a lot of $, and if you are even minimally handy w/tools, assemble them yourself. 
DIY balanced interconnects
I use Mogami Gold between CD and amp. Clean, and available at the nearest Guitar Center. 
90db, 7ohm speakers: tube amp recommendations?
Impedance is just one part of the 'load' an amp sees.perhaps even more important is the phase angle.... The difference is expressed in degrees and is primarily caused by the inductors / capacitors / back emf in or generated by a speaker. 2 speaker... 
Rogersound speakers?
RSL was a Southern California 'boutique' brand many years ago. Sold my 3600s to fund the purchase of Magnepan MG-1sfrom which I have not looked back.The 3600's were a reasonable clone of the than popular JBL4311 model. I liked the RSL 3300s better... 
Looking for amplifier kits.
Hypex sells class 'd' semi-kits. Well regarded in some circles and has many of the virtues of there ilk. You can buy amp modules, PS modules / a transformer and 'case' it yourself. I have the International Rectifier class 'd' reference amp sitting...
