| Is a stereo amp, when bridged to mono, by definition differential? If you are talking about one of Steve McCormick's designs in the context of this question, you have no worries. He knows what he is doing and his inputs work correctly. | |
| My 50W, 8ohm amp can't drive my 86db, 4ohm speakers? WTF?? Again, I'm wondering how a rectifier can fail - it's under-spec'd for the job, an AC power surge during a bad electrical storm, power supply capacitor does not have a DC path to ground to discharge when the amp is turned off thus discharges thr... | |
| CHINESE tubes? We used to use the Russian 6SN7s. They really didn't perform well and were unreliable. About 1998 or so we switched to Chinese 6SN7s and they have been treating us quite well. They are not the best sounding 6SN7, but they are not bad. They are cop... | |
| Harman/Kardon Receiver If I'm not mistaken, the 430 was part of their lineup that used separate power transformers for each channel. So its a dual-mono design in a single chassis. That is a good portion of why it does what it does. | |
| What is best turntable for listening to Rock from the sixties like Led Zeppelin? It is entirely possible to optimize the TT for one genre over another. Much of that is merely cartridge /tonearm selection. Though the selected cartridge/tonearm may be entirely fine in all other genre's, it has been voiced by its owner for o... | |
| Disadvantages of a direct coupled preamp? I want to know what the disadvantages of direct coupling are, particularly if anyone knows details of the implementation in my Line 2. If direct coupling was the bee's knees, wouldn't all high end gear do it?We make two preamps with direct-coup... | |
| Is a stereo amp, when bridged to mono, by definition differential? If the balanced input only operates when the amp is bridged, then it is considered balanced but not differential (even if the individual channels are differential). set up this way the Common Mode Rejection Ratio (CMRR) will likely not be very goo... | |
| What is best turntable for listening to Rock from the sixties like Led Zeppelin? Point was that a particular record player can be made to sound better playing back one musical genre over another. This is complete nonsense. Its like saying a turntable might be better at 80's down tempo rock but can't do Jimi Hendricks. Equip... | |
| 6sn7 or 6sl7 FALSE?,Maybe you haven't tried but I've been doing this for almost 10 years and not a single tube fail,a living proof.BTW,my preamp has stock 12ax7.I'm sure you've gotten away with it. I've done the same. But I can tell you for a fact that all t... | |
| What is best turntable for listening to Rock from the sixties like Led Zeppelin? A lot of the rock recordings from the 1960s are really well recorded! The more resolution the better. | |
| 6sn7 or 6sl7 Hi,You can plug in any 6sn7 gt,gtb,gta wgt,w,& A / 5692/VT 231 or 6sL7 / 6SU7. without any problem with your amp or preamp,I been doing these any time and I even have an adapter for 12AX7/12AU7/12AT7/12BZ7 to the 8BD BASE socket and they ... | |
| need balanced tube preamp used You might be able to find one of our MP-1 preamps used for that price. The MP-1 is fully differential and balanced and historically was the first balanced line preamp made. It has a direct-coupled output and so can drive loads that most tube pream... | |
| Preamp upgrade opinion... Thanks for your response. Would the BAT VK-50SE match well with my X250? RIt should. Have you expanded your budget? | |
| Changed amps - center image moved The next step is to get rid of the adapters, perhaps having the XLRs installed on the ends of your existing cables. I find that adapters often eat some of your dynamic impact, and its an easy thing to fix. | |
| New amp for Vandersteen 2CE Atmasphere - fair point, the kids aren't babies anymore, so it's not as big of a concern as it was a few years ago. There doesn't seem to be much available used below $1k. Any thoughts on particular models that might be interesting to look at... |
