| Disconnect the woofer I agree with Rodman. It depends on the crossover configuration. If it is more than a first order crossover (i.e., an inductor in series with the woofer), you would want to open the INPUT to the low frequency part of the crossover network, not its ... | |
| Hard Drive versis Flash Drive Whether the music files are stored on an external flash drive or an external usb or firewire hard drive has no relation to how the music is communicated from the computer to your dac. In each case, the computer has to read the music file from the ... | |
| What the most musical power amp for under $1K? Although I haven't heard them myself, I think that if you research user comments here and elsewhere on the McCormack DNA 0.5, you will conclude that Swampwalker has made an excellent suggestion.Your reaction to hooking up your NAD is typical. We a... | |
| RF interference through my phono stage. That's not uncommon. See the following thread, in which the problem was ultimately resolved by connecting a braided rf ground strap between preamp chassis and power conditioner ground, and between power amp chassis and power conditioner ground. Si... | |
| Ripping 700 CD's to HD using FLAC-How much space? See the following thread for some things to think about before opting for RAID as your backup solution:http://forum.audiogon.com/cgi-bin/fr.pl?icomp&1243817965Regards,-- Al | |
| Interconnect Inductance vs. Capacitance Vett93 -- It's been too long since I studied Thevenin's Theorem. It looks like I was right, and bandwidth will be greater when the attenuator is set for 12db attenuation, compared to when it is set for 6db attenuation.The Thevenin equivalent circu... | |
| Suggest speaker cable for long run...? I took a look at the OCOS description. While I have no reason to question its being an excellent choice for longer runs (and at $1K for 7.5 meters it had better be!), I find the design rationale offered there to be, um, unpersuasive and incomplete... | |
| Interconnect Inductance vs. Capacitance Mathematics R us! lol...LOL here too! As someone who also has multiple EE degrees, albeit one fewer than you do, this thread is definitely fun!Agreed on the 6db, given your power amp's relatively low sensitivity. But I also chose 12db for my examp... | |
| Interconnect Inductance vs. Capacitance Shadorne -- Thanks for your observations. I just want to make sure it's clear to everyone that my previous post was written before I saw your last post, and was in response to the prior posts, not to your good observations.Regards,-- Al | |
| Interconnect Inductance vs. Capacitance I agree with Vett's calculations, and the 12.5kHz answer. When I said that interconnect capacitance could become "marginally significant" under extreme circumstances, I was thinking of source components with active output stages. For passive pream... | |
| Interconnect Inductance vs. Capacitance Just out of curiousity, do you think that anyone selling cables has IC designs that would exhibit enough capacitance to grossly affect high end frequency response? Isn't this more an issue for the designer than the consumer? No, as far as I am awa... | |
| Suggest speaker cable for long run...? It depends on your speakers and your amplifier. For that long a run you obviously want a cable that has low resistance, low inductance, and low capacitance per unit length. How low is low enough will depend on speaker impedance and amplifier outpu... | |
| Long Firewire Cable Runs I use a Belkin firewire hub to tranfer digital video data via firewire between my pc and a dv tape deck, across a similar distance. That involves far higher data rates than any audio format, and I've never had a single dropped frame, or any other ... | |
| McIntosh MC-75 in unknown condition, what do I do? Oops! The first sentence of the last paragraph of my preceding post should have read:Apply the polish with cloths or cotton swabs, being very careful NOT to get any of it on the lettering, and being careful not to get it into crevices from which y... | |
| McIntosh MC-75 in unknown condition, what do I do? It would obviously be desirable to run the tubes across a tube tester, but if you don't have access to one I think it should be safe to try the amp without first testing the tubes, PROVIDED that you use a variac or equivalent to bring up the volta... |
