| Wiring a subwoofer to monoblocks PS Audio HCA-2: I sent a request on their tech support forum and was told by Paul McGowan who responded to the post to install a 1Kohm resistor in line with the black wire and the negative speaker terminal (I had tried the Ayre chassis screw trick... | |
| Wiring a subwoofer to monoblocks A monoblock amp may or may not be a differential amp. A differential amp is also referred to as a fully balanced amp, or at least an amp having balanced outputs (meaning that the red and the black speaker terminals are both actively driven with si... | |
| Quick poll How long have you been in this hobby? Since 1971. | |
| Turntable Hiss It makes more sense to find a cartridge to match the preamp. Ron -- Note that she already has a 5mv cartridge. No moving magnet or moving iron cartridge, to my knowledge, is going to provide a great deal more output than that. I believe there are ... | |
| Bi wiring? First, if you are using the preamp section of the receiver you can't bi-amp unless the receiver provides output jacks from its preamp section. Otherwise you would have no means of providing inputs to the separate power amp that are controlled by t... | |
| Bi-Amping questions You'll find this post by the noted designer Steve McCormack to be well worth reading.Also, I believe that contrary to widespread belief the 3db power increase (i.e., twice the power) that is commonly cited for bi-amping vs. single amping will in m... | |
| Turntable Hiss Hi Katie,It's possible that better cables will help somewhat, but my guess is that the main reason for the hiss you are hearing is the 540P phono stage, and unfortunately I suspect that the only way to substantially reduce the hiss is to substitut... | |
| VSA VR-4: problem with midrange drivers My concern was that perhaps the drivers in the top module weren't capable of handling that much power alone.To clarify my previous comments a little further, the mid/hi speaker drivers will see exactly the same amount of power when bi-amped as whe... | |
| VSA VR-4: problem with midrange drivers If I use a lower powered amp on the top end ( I have a 100 wpc Aragon not currently in use) would that make any sense? I will also have the B&K checked out to see if there are any issues with it, but I'm concerned that sending 200 watts to the... | |
| jumper pins for xlrs Thanks Steve; no problem. Let me make sure it's clear, though, that nothing in my posts was intended to question the advantages of balanced interfaces or balanced internal signal paths, which I am certainly a believer in. Keep in mind that a balan... | |
| jumper pins for xlrs Steve,What is the experimental or theoretical basis of your disagreement? And what sort of sonic deficiencies are you envisioning, beyond the possibility I mentioned of a minor increase in background noise levels?Elaborating on my previous respons... | |
| jumper pins for xlrs If you are referring to jumpers that connect pins 2 and 3 together on xlr input connectors, no you won't be hurting anything by not connecting the jumpers. Most likely there won't be any perceivable sonic penalty either. At most there might be a v... | |
| HELP I think I have an electrical issue?? Tim -- Good to know what the explanation turned out to be, and that you were finally able to fix it. Thanks for letting us know.Best regards,-- Al | |
| New amp being touted as among the best ever...... Gentlemen,Here is a link to their USA patent:uspto.govThe HFNRR review can be downloaded as a pdf here:absolutesounds.comPage 3 of the review has a box describing in very general terms how it operates. The patent includes considerable additional d... | |
| Amp sub crossover and a sub crossover I agree with the others. I'll add that having two 80Hz low pass filters in series would result in a bandwidth that is significantly less than 80Hz.Also, according to the review of the sub that is linked to in your system description it looks like ... |
