| "Can You Lift Yours?" Any correlation of sound quality to weight has to be predicated by amplifier topology. Traditional tube amplifiers probably have the strongest correlation here, because the size of its transformers (power plus 2 outputs) generally dictates how muc... | |
| "Can You Lift Yours?" The Citation II doesn’t look like it weights nearly 120 lbs. Where’d you get that number? I would have guessed 80 max. My VAC Master 300 monos are ~ 135 lbs each. I had them moved here by the dealer. Not worth the risk. I’ve got 2 other tube mono ... | |
| Your experiences with system synergy Not too surprising. Yes, that nebulous / nefarious concept of "synergy" is crucial. Everything matters for a good amp match, not just speakers: preamps, source, volume level, music selection, and YOU. Psychology is a factor too. If you’re expecti... | |
| Reliable source for 6550WE tube - Audio Research Ref 6 I’ve bought a few sets of power tubes from Viva Tubes, and they’ve all been good. They’ve been low on Russian power tube stocks for months, but still have some of those Sovteks, plus EH and Mullard KT88. You can also use KT88 or KT90 in the Ref 6 ... | |
| Four Hour Tube Amp Warm-Up Never experienced anything like that with pure tube amps. In fact I always find them quick to warm up. I once had a hybrid electrostatic headphone amp (grounded grid EL34 with solid state CCS outputs) that took like an hour to sound its best -- bu... | |
| Buying Used Equipment on the Internet I bought and sold a several components on usaudiomart. It's about communication, you pretty much have to figure out if the person on the other end is trustworthy. Ask some questions that aren't realistic but the responses will be telling: "I wil... | |
| Buying Used Equipment on the Internet The vast majority of 100% feedback, hobbyist gear traders on here are not going to stick you with a "lemon". I once sold a DAC that arrived DOA -- somehow it went bad between my last listen and arriving at the buyer. After a couple hundred transac... | |
| Audio Research REF 750 pre July 4 FIRE WORKS. TUBE ARC. VAC and others have built and sold monster tube amps with vertical designs but power is useless without reliability and user-serviceability. Even the biggest VACs still use only 8 output tubes per side, compared to 16 in each Ref 750! At that p... | |
| Audio Research REF 750 pre July 4 FIRE WORKS. TUBE ARC. Yes, I had similar happen in 2010. I know it sucks. It was an EH KT90 in one of my Rogue Apollo monoblocks. They're no lightweights at six KT88/90/120 per side, but still nothing like your 750! Anyways, yeah a few seconds of fireworks and then a p... | |
| Benz Micro Glider Loading I can suggest: The Hagerman Trumpet MC is very flexible, easy to adjust in gain & loading with front knobs, sounds great, and doesn’t cost much. Its main limitation is lack of adjustable capacitive loading for MM. It has a warm sound that goes... | |
| Benz Micro Glider Loading You have a "Medium" output Glider at 0.9mV and 24 ohm coils. Folks running a Glider below 200 ohms typically have the "Low" output version, at 0.3 - 0.4mV depending on series (e.g. L2 versus current SL) and 12 ohm coils. Therefore there are differ... | |
| Bridged amps vs stereo vs monoblocks. So we all know V = I * R. Bridging a 2ch stereo amp to mono doubles the output Voltage, halves the load Resistance each amp channel "sees", and then because of this each amp ch also *tries* to supply double the current (I), but how much of that i... | |
| Can’t buy output tubes anywhere except from manufacturers at high prices. @weebeesdad Yes, I have the Viva Mullard KT88 in my 200iQ’s right now. I’ve previously (this year) had both Gold Lion KT88 (stock from VAC) and Tung-Sol KT120 in these same amps. I haven’t directly compared the two, and I’m not going to say they... | |
| Can’t buy output tubes anywhere except from manufacturers at high prices. Viva Tubes has them. The prices are up but, the price of everything is up now.. They've been out of KT120 and Gold Lion KT88 for a while now. And their supplies may be dwindling on remaining Russian KT88, EH KT90, and KT150. Mullard KT88 are ... | |
| Turntable Isolation Journey I may come into a windfall and am considering an Innovation Wood Black/Piano Black with black 12" Universal. I already have a Lyra Atlas Lambda SL, so that should be a killer combo. @dwette Lovely! My experience is that this Universal 12" arm ... |
