| Anybody listen to Ohm Walsh speaker w/digital amp? There is some interesting discussion of Class D amps in this thread:http://forum.audiogon.com/cgi-bin/fr.pl?aamps&1229914799They do, as you appear to realize, tend to have extremely high output current capability, and very low output impedance... | |
| MC and Step-Up Cartridge Loading If your gain structure is good with the 17:1 then I would definitely try changing the internal R to a larger value. I agree. I made the suggestion about an external resistor before finding (if I correctly interpret the statement in the specs I li... | |
| MC and Step-Up Cartridge Loading According to the specs shown here:http://www.arcdb.ws/SP8/SP8.htmlthe phono input overload point is 900 mv, not 9 mv. (Of course, it's safe to assume that output clipping would occur well before that large an input were reached, given the 60db gai... | |
| MC and Step-Up Cartridge Loading Changing the internal 47K resistor in the preamp to 120K will not affect the gain significantly, but has the two potential disadvantages that I mentioned (internal preamp modification; possible subtle electrical effects). Putting an external 73K o... | |
| MC and Step-Up Cartridge Loading I agree with Herman's comments, but I'll add a couple of things:1)The main effect of resistive loading of a moving coil cartridge is to smooth out what would otherwise be an ultrasonic peak in the frequency response:http://www.hagtech.com/loading.... | |

| Favorite Female vocals that give you goose bumps and if Almarg can do it so can I...Doris Day could swing with the best of them.LOL ... Actually I briefly toyed with the idea of putting "Secret Love" on my list. I decided not to, but I'll give it an honorable mention!Regards,-- Al | |
| Do cold temperatures damage audio equipment? Somebody once told me that you need to let the equipment warm up to at least 40 degrees before you turn it on. I don't know why that number was picked but that is what I usually told customers. DanThat's a pretty reasonable guideline. Commercial g... | |

| Do cold temperatures damage audio equipment? Electronic components such as transistors and integrated circuits, even in their cheapest commercial grade form, are usually rated for storage (non-operating) temperatures down to -55 degC or -65 degC or thereabouts. Brrr!I think that the biggest ... | |
| Bi-amping via Y-cables sound quality Most preamps that have two sets of outputs simply jumper the two sets of jacks together internally. So electrically there is no difference between that situation and using a y-adapter externally (assuming the y-adapter is of good quality).Keep in ... | |
| can biwire cables be used on a non-biwire speaker? You're welcome! You undoubtedly realize this, but just to be sure, if you try it with your present bi-wire speaker terminals you'll have to jumper the high and low frequency speaker terminals together.Regards,-- Al | |
| can biwire cables be used on a non-biwire speaker? I'm not familiar with the particular cable, but I'd feel certain that it does not contain a crossover network that would route different frequencies to one or the other pair of wires. At most one pair of conductors might be optimized for higher fr... | |
| can biwire cables be used on a non-biwire speaker? I don't see any problem with doing that, as long as the gauge is sufficient. If I understand your question correctly, one of the two pairs of conductors would be left unconnected at the speaker end. Concerns that might be raised about the unconnec... | |
| Preamp inverts phase question: Al, remember that when you switch speaker cables you are also affecting wire directionality, or so I've read. In fact, I remember Doug Blackburn writing an essay on polarity suggesting that the primary audible change you hear (if you hear ANYTHING... |
