| tube amps sounding like solid state and vv Typical tube circuits have very few components in the signal path, and are therefore much more transparent than SS designs. Victor Khomenko of Balanced Audio Technology has simplified the circuits of BAT's SS units, re-thought/re-designed their po... | |
| What is a passive preamp? OBVIOUSLY- The manufacturers(with VERY few exceptions) consider a linestage that CAN provide gain(requires a power supply or "active" circuit) to a signal passed through it(AMPLIFY said signal), whatever the source, a "PREAMPLIFIER." A linestage w... | |

| How do I go about bi-amping Martin Logan Ascents Trumpetdoug- This thread contains discourse that you may find helpful: ( http://www.martinloganowners.com/~tdacquis/forum/archive/index.php?t-460.html ) Especially the last five posts to the thread. If it IS your intention to retain the internal p... | |
| How do I go about bi-amping Martin Logan Ascents An Attenuator would match the sensitivity/gain which is one of the main issues of bi-amping with two amps that I mentioned. What about the overlap in frequency that he WILL have without a crossover or filter? Some of the greatest audible gains inh... | |
| What is a passive preamp? RWEAR- You'll have to stop using AR as a reference. Check the Audio Research Corporation's OFFICIAL website and look at the LS-26 page! Audio Research Corporation refers to the LS-26(Line Stage-26) as a PREAMPLIFIER, and it has no phono stage. (As... | |
| What is a passive preamp? ARC(see the LS-26 page), Lamm, Levinson, Edge, Van Alstine, Herron, Joule-Electra, Conrad-Johnson, Aesthetics, Musical Fidelity, Ayre (to name a few) If you visit the sites of the manufacturers I've named: You'll note they ALL refer to their pream... | |
| How do I go about bi-amping Martin Logan Ascents Any time two amps of different power outputs and/or sensitivities are used to bi-amp a speaker system, a matching x-over must be used to retain a correct freq. response. Anyone that tells you differently simply doesn't know what they're talking ab... | |
| What is a passive preamp? No- Because they have the capability of amplifying(adding gain to) the signal. In some countries they are referred to as a, "control Amp." That is, perhaps, a more accurate description. | |
| what can I get by with? What can you lose by trying them? As stated: It all depends on your room size and the volume you require to be happy. | |
| Planar close to a rear wall? Quad for example? I have to agree- Dipolar radiators just DO NOT do well close to the rear wall. | |
| Tubes for my Mac's 275....NOS or just used? I've purchased the majority of my NOS tubes on eBay, or from eBay contacts over the last 5 years. All the purchases(probably 40+) were excellent, but for one(if you e-mail me, I'll let you know his user name). I got four counterfeit Telefunkens fr... | |
| What does more power do for Magnepans? The biggest problem with that calculation is that to obtain a subjective doubling of loudness requires ten times the amplifier power. See: (http://www.gcaudio.com/resources/howtos/voltageloudness.html) | |
| What is a passive preamp? Actually "preamplifier" Means, "an amplifier before" something else, just as "pre-driver" means a transistor or tube that drives (provides a gain stage) before an output stage. Obviously- A preamplifier would be placed BEFORE a power amplifier, an... | |
| Designer Hall of Fame Stereophile does a much better job of remembering David Hafler's history than I could here, although they pass on how he popularized the "ultralinear" tube circuit:( http://stereophile.com/news/11661/ ). Bill Johnson single-handedly resurrected tu... |
