| Amplifiers and Horn Loudspeakers Why do you think it is that amps with zero or very little negative feedback sound so much better than those with lots? And that on amps with adjustable feedback changing it is indeed very AUDIBLE?Horns for the post part are expecting constant powe... | |
| Opportunity to buy the best Preamp... but which? There's been no discussion about SE/balanced... in preamps this can be a big deal on account of the interconnect cables.So- if funds are unlimited for a preamp, what amps do you have? Will they accept either input? | |
| Replacing metal oxide with Vishay/Dale metal film The Vishay metal films will be an improvement. To really get what they are about, you will have to replace all the resistors in the signal path and all those that are in the cathode and bias circuits as well.Coupling caps are another area you can ... | |
| What do you look for in damping factor? Ralph, I am slightly confused. Are you trying to say that:A. The perceivable synergy of the Rowland 312 and the Mahlers exists in spite of the amps high damping factor?B. The 312's damping factor is immaterial to its synergy with speakers in gener... | |
| What do you look for in damping factor? Damping factor plays a role in system performance, just not a large one. Damping factors above about 15 or 20 to 1 will result in no audible improvement, but such amplifiers that do have such damping factors have proven themselves incapable of pla... | |
| Why Tube Pre-SS amp over SS Pre- Tube amp? Alright- I'll bite- The reason tube preamps are often preferred over transistors is that they loose less of the signal. Transistors are pretty good at loosing low level detail so if you have transistor preamp driving a tube amp you will be missing... | |
| Running monoblocks in parallel to increase watts?? Bridging is definately balanced. That is why you see bridge-able transistor amps with balanced inputs that only run in balanced mode. But there is no association with greater gain, although it is possible to achieve greater gain with less noise wh... | |
| balanced pre amp Phono cartridges are a naturally balanced source too. It really seems to help running them balanced! | |
| Running monoblocks in parallel to increase watts?? The inversion technique works with transistor amps (and is the way that car stereos get 15 w/channel while running only 12 volts).That technique is: the load goes between the two '+' outputs. This assumes that the '-' outputs are tied to ground. O... | |
| Tube Amp & Preamp for ML Summits? Hi Pal, some of our customers have reported very good results using the MA-1 with the Summits. Recently one of our dealers reported that an audition went very well with M-60s too. So my comments are based on customer reports, which jive with our o... | |
| Tube Amp & Preamp for ML Summits? Definitely consider tubes- for some reason the Summits are bit easier on tubes than some of the other ML models (even our M-60 drives them). Tubes and ESLs are the tradition since the 1950s- its the right thing to do. Above all have fun! | |
| Could this be a Major Breakthough ? Long story short: no. | |
| Balanced SET? North Audio We've done something *like* this for the last- 29 years? or so... (of course we got rid of the output transformer too). What we found was that to be effective *every stage* in the amplifier had to be summed in balanced mode- in effect every stage ... | |
| Avantgarde Trios, SETs, and Impedance Curves I have a friend with the ART PX-25- its not bad on the Trio at all. There are no 45-based SETs that can drive the speaker- try as you like, 0.75 watts is not enough...Most people I know that are driving the speaker successfully use surprisingly la... | |
| Are monoblocks better than stereo, with tube amps? I prefer to run mono amps which allow me to run very short speaker cables with long interconnects. OTOH, I run everything balanced, so I can get away with that. |
