| ???What's The LEAST Expensive "End Game"Amplifier You've Ever Heard??? The very best sound quality is from single-ended amps. @imjerrys They don't really make proper bass- most SETs that make 7 Watts or more can't make full power at 20Hz. The output transformer simply lacks the inductance to allow it. If it did ha... | |
| Can anyone tell me when XLR connections were first used on stereo equipment. (what years)? @mewsickbuff Atma-Sphere was the first home stereo manufacturer to regularly offer balanced line products. The MA-1 amplifier was first in 1987 and the MP-1 preamp followed in 1989. Both not only had balanced inputs and outputs (including LOMC pho... | |
| Suggestions for phono preamp for LOMC's @bobheinatz Here's a tip for buyers of phono sections that can work with LOMC cartridges. If it has provisions for a loading resistor for the cartridge, its a pretty good bet the designer didn't think thru the implications of an inductive sourc... | |
| Recommendations for a jazz record which demonstrates vinyl superiority over digital I have an entry-level Krell KSB-7B pre-amplifier with external power supply so I doubt that RFI is a problem there, but who knows? @richardbrand The RFI is injected directly into the phono input by the tonearm cable. If the preamp has provision... | |
| Pre amp recommendations @dahodevil Since your amps have balanced inputs, for best results a balanced preamp should be used too. The advantage of balanced line is the cables can be completely neutral (and thus musical in every way) but to do that the preamp has to support... | |
| The Shure V15 V with a Jico SAS/B stylus VS The Soundsmith Hyperion MR and Lyra Atlas SL I am impressed that your subwoofers can do zero Hz. @lewm Eminent Technology's sub can do DC if the blades are locked In fact a fan is what gave him the idea. | |
| Recommendations for a jazz record which demonstrates vinyl superiority over digital @richardbrand The condition of the master tapes is an issue that anyone interested in digital has to face. In many cases, they’ve degraded a lot since the original LP was pressed. So the digital release won't be as good. For this reason, if you a... | |
| Single ended = large images? Re: 6C33C tube. Years ago, I owned these Artemis monoblocks. Depending on the bias setting, the 6C33C tubes lasted somewhere around 2000 hours or so. I used to buy them in bulk @ 20 tubes/order - directly from Russia or Ukraine. Now with the war... | |
| Why tube rectification? @invalid This is an interesting assertion. If you were building a 60 Watt PP amp based on KT88s what rectifier would you use? | |
| Why tube rectification? Could appropriate HEXFRED diodes be used to replace the existing diodes in each amp without other modifications? If the equipment is already designed with solid state rectifiers then yes, there are HEXFREDs rated at 1200V with plenty of Amperag... | |
| ??? Fuse UpGrade??What Size??? @freediver Littlefuse and Bussman make the best fuses around IME. Just for fun, you might obtain some and then do the same listening test that you did in your post just above. BTW running an overrated fuse is bad advice. If for any reason your eq... | |
| D amps @hgeifman FWIW, class D amps vary in sound more than tube amps seem to. So having a bad experience with one isn't an indication that another will be the same thing. The Hypex and Purifi modules are sold as parts so you have to come up with a power... | |
| Why tube rectification? there is no reason to have voltage sag at higher power with tube rectified equipment if the proper rectifier tubes are chosen. @invalid Yes- I like the plural of the word as you chose, as that is what is needed. For example the Dyanco ST70 was ... | |
| Why tube rectification? These two competing solutions both supply the basic power to the audio tubes and output transformers, so only indirectly interact with the sound signal. I have not read anything that explains what tube rectification brings to the party. Voltage... | |
| Does Anyone Know the History of the Early Sota Turntables? @neonknight IIRC the original mat was acrylic. Oracle makes an excellent patter pad that would be well suited on there. |
