4 ohms and 8 ohms
Cibr...If an 8 ohm speaker is connected to the 4 ohm tap of the amp, the voltage delivered will be less than the amp could deliver at the 8 ohm tap, so the available power is reduced. If a 4 ohm speaker is connected to the 8 ohm tap the current de... 
4 ohms and 8 ohms
Solid state amps output a voltage which, within the power capability of the amp, is unaffected by the load. Maintaing the voltage with a low speaker impedance requires output of more current (amps), so the low impedance speaker will draw more powe... 
SDS question
What kind of motor is this, and how is the speed regulated?Variation of line voltage (but not the frequency) is common, and I would be surprised if a TT was sensitive to voltage variation (within reason).For example, my DD turntable has a strip of... 
SDS question
OK...I forgot belt slipage. I am a DD guy where the speed of the platter is the same as the motor, and the motor is exact. I really don't think that there should be any belt slipage...you probably need a new belt. 
How long can one go with interconnects to a cart.?
Audiofeil...Rwwear says he tried it, so I would trust his opinion over that of a "high end cable manufacturer". Those guys are more famous for black magic than for "solid scientific principles". Could you tell us what those principles are? I agree... 
SDS question
Its been a while since I was up to date on TT technology. What kind of motor is used? A synchronous motor, common decades ago, would assure that the rpm was exact ("dead nuts" is the technical term). Bearing lubrication, temperature or phase of th... 
Class-D amps - a different re view
Mrtennis...Not an absolute predictor, but a useful indication. Why else do we contribute opinions, pro or con, on this web site? 
How long can one go with interconnects to a cart.?
Audiofeil..."lengths of 10'or 20' as suggested *CAN* cause severe degradation of the signal". Did you ever actually try it?I am a believer in short cables for speakers, but in that case there is a lot of current flowing. Of course I personally hav... 
Speaker "pops" when power amp shut off
They do that. Use the proper turnoff sequence. 
How long can one go with interconnects to a cart.?
I admit I haven't tried it, but it seems to me that a long interconnect (say 15-20 ft) might be OK. The current from the cartridge is tiny, so resistance is not an issue. Capacitance might be, depending on what the cartridge wants, and hum might o... 
Audiophiles vs DIY-o-philes
At least in my case DIY is very much driven by the quest for better sound within a given budget. In the case of speakers, many were designed ENTIRELY by ear, with nary a measurement. Nowadays we have the benefit of much research into the behavior ... 
Oppo 980H setup and use
A TV is useful. Get yourself a small cheap TV dedicated to setup. A 13" will generally be cheaper than a 9" (strange but true). Mine cost $79 at Best Buy. 
Class-D amps - a different re view
Atmasphere...When transponders (radar response avionics for planes) were first introduced they were all transistorized except for the output device which was a traveling wave tube. The high RF frequency used by the transponder was cited as the rea... 
Class-D amps - a different re view
Muralman1...You said "Never will class D emulate the fantasyland of tube amps" but I suggest that your descriptions of your H2O amp come darned close :-) 
Class-D amps - a different re view
Atmasphere...Since the output devices are simply ON/OFF switches, I see no point in using tubes here. The supposedly superior linear amplification characteristics of tubes would not be relevant. At the input, a tube could be used, but why not put ...
