| Tube Amp for Martin Logan Speakers George, where do you see an indication of a MEASURED damping factor of 4.7?Regards,-- Al | |
| Tube Amp for Martin Logan Speakers Correction to my previous post: delete the word "ohms" which appears immediately following the number "4.7"Regards,-- Al | |
| Tube Amp for Martin Logan Speakers George, if I may be a bit pedantic as well, although multiplying the 1.5 ohm specified and measured output impedance by the specified damping factor of 4.7 ohms equals 7 ohms, both the manual and this page at the Manley website clearly state that ... | |
| Tube Amp for Martin Logan Speakers Hi Unsound,The Manley Snapper has a single output tap, which is described as having been optimized for a 5 ohm load. Its output impedance is specified as 1.5 ohms, as George indicated. Its specified damping factor of 4.7 is slightly inconsistent w... | |
| Your favorite musical non fatiguing speakers? Daedalus Audio speakers should definitely be considered IMO, although most of their models would only fit within your price range if bought used (and they appear for sale only occasionally). Regards,-- Al | |
| What's the best EL34 amp besides 8b? What's the best EL34 amp besides 8b?... I am looking for a tube amplifier with 4 tubes of EL34 push-pull.Among amplifiers employing two EL34's per channel in push-pull, I suspect that a pair of Marantz 2 monoblocks in good condition would outperfo... | |
| Do Vandy subs benefit from better cables? The speaker cable provided by Vandersteen seems rather light. That is because the input to the sub is the input to its amplifier, which has a specified input impedance of 100,000 ohms, and therefore draws negligible current and power. So heavy gau... | |
| Need help determining next upgrade - 3rd ATTEMPT Small square rooms tend to be particularly problematical, and I second all of the responses that have focused on room treatments and speaker positioning. In fact, looking at the photo of your setup I would be very surprised if you did NOT have the... | |
| has anyone else experience this..... Hi Tony,Regarding calibration, all I can cite is my own experience. I've had the 800A for a bit more than 20 years, and used it lightly from time to time during that period. I have a very large collection of vintage tubes that I use primarily in c... | |
| has anyone else experience this..... TLS, thanks for the good articles, and the good points you provided in your post. As you and Bill_K indicated, the term NOS is unfortunately used too loosely too often. With the problem being further compounded by the existence of fakes, as Elizab... | |
| Tube Amp for Martin Logan Speakers Bruce, thanks. Youre welcome!If ZEROs are used to double the ML's apparent impedance plot, would that change your calculations?It would narrow the gap somewhat. The 11 db figure for the solid state amp wouldn't change, but the 6 db figure for the... | |
| Tube Amp for Martin Logan Speakers 03-29-14: Bifwynne Perhaps Ralph or one of the other tech members can speak to how much SPL variation will result if the "wrong" type of amp is used. Perhaps, for discussion purposes, we should assume the MLs were designed to be driven by a SS "co... | |
| has anyone else experience this..... i recently purchase a pair of mullards nos tube for my pv10 Conrad Johnson .... they were used.............A point of information: "NOS" = "NEW Old Stock" = unused.Regards,-- Al | |
| XLR/TRS to RCA? Adapters or cables? In the situation you are describing the one concern I would have with respect to the use of an adapter is that most (but not all) XLR to RCA adapters short one of the two signals in the balanced signal pair (usually the signal on XLR pin 3) to gro... | |
| "Against design" So there's really no sonic improvement to be gained by using hardwood?See the post by Lou Hinkley of Daedalus at the link I provided earlier. I would not consider your statement to be a precise summation of what he said.Regards,-- Al |
