| 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... | |
| Designer Hall of Fame Am I showing my age by mentioning William Zane Johnson(ARC), David Hafler(Dyanco,etc.), John Dahlquist, and John Curl(the Levinson JC-2)? Each of these men produced designs that rocked/created the "high-end" world. | |
| Most resolving, transparent amps. Phd- This company:(http://www.thecableco.com/about.php) allows you to try cables in your home, without risk, before you buy. That will eliminate any costly errors/possible system mis-matches. happy listening!! | |
| KT88s for Audio Research VS55 I'd been using NOS Phillips ECG's in my Cary SLM-100's for a long time, and couldn't bare the thought of changing to new production anything. That was until I found out what the prices had done on matched octets of ANYTHING NOS. Almost impossible ... | |
| Integrated Tube Amplifier for First Timer? Look at these pieces, and read all the reviews: (http://www.upscaleaudio.com/view_category.asp?cat=36) They have some very worthwhile(user friendly) features too! | |
| Second failure of new amplifier As long as you rolled the tubes with tubes of the exact same family(IE: 6DJ8/6922/6H23/7308/E88cc/E188cc/CCa) it should not void the warranty. Burn-in time has absolutely nothing to do with an amps affinity for blowing tubes. Sometimes the transla... | |
| Need quick answer- BAT VK3iX vs. BAT VK3ixSE One more thing- If you buy the iX and shop for 6922's: ALWAYS specify LOW NOISE tubes. Of course- The ones in the SE will already be LN. | |
| Need quick answer- BAT VK3iX vs. BAT VK3ixSE With the iX version- You will have the ability to try a wide variety of 6922's, while the SE will restrict you to Two choices, the 6H30 or 6H30pi. I've got a VK-D5 Cd player and have stuffed it with 6 NOS Siemens CCa's from the 60's. The accuracy/... |
