| If I'm looking for "Tube Sound", why would I put a Tube Pre in front of a SS amp? @sbank you might try out a preamp that uses 6SN7s... once you hear what the 6SN7 does its hard to go back to miniature tubes. | |
| If I'm looking for "Tube Sound", why would I put a Tube Pre in front of a SS amp? The reason to put a tube preamp with solid state is if you have to compromise and want the benefit of tubes, a tube preamp will give you smoother sound and more detail than a solid state preamp. There is no way to gloss that problem over downstrea... | |
| Need amp suggestions for Hedlund Horns.... The impedance and efficiency make a lower powered OTL a good choice as well. | |
| Tube Amp vs Solid State Amp HELP Is there a reason why you are stuck between those two particular amps?? | |
| Loudspeakers have we really made that much progress since the 1930s? Great article by Art Dudley in October Stereophile. He comes down squarely on the side of the best vintage speakers not having been surpassed or even equalled by modern speakers.What is meant by 'the best vintage speakers'? old Quads? Hartsfiel... | |
| Designer Hall of Fame Just a FWIW- Harvey didn't do any designs. Its George Kaye that was largely responsible for the NYAL designs- or Julius Futterman. | |
| mc cartridge loading In all the years I have been reading and talking to engineers who are involved with step up trans and carts this is the first time I ever heard this.Apparently they don't know the physics of phono sections. In the case of an SUT you have a diffe... | |
| mc cartridge loading The loading only needs attention if the phono section is sensitive to RFI at its input. The RFI is generated by the cartridge itself in part due to the afore-mentioned resonance that is set up by the inductance of the cartridge and the capacitance... | |
| Beyond Ayre Pass and Rowland So, the best solution could be a custom amp for particular speakers, and I mean for a particular pair of speakers.Very occasionally. Usually we see speakers built for a particular amp. But if we were a speaker manufacturer it might be the other wa... | |
| SET 45 Amp Driving Dynamic Speakers I've often been amused by the comments in Stereophile about how an SET can measure so poorly and yet sound so good- and further that no-one seems to know why. I have to assume that they did not ask any designers when that comment was made.IMO low ... | |
| Beyond Ayre Pass and Rowland There are a lot of nice comments here. One thing I think needs to be emphasized is how important the match is between the amplifier and loudspeaker!For starters, all amps make less audible distortion when driving higher impedances. To this end, if... | |
| LP: Left Channel Drops In and Out Could happen. The cutter is an analog lathe, so it’s definitely possible that the master for the LP was cut when one channel stopped working. These pressing masters need to be re-cut every so many LP's, so it's quite possible that in a large ru... | |
| SET 45 Amp Driving Dynamic Speakers If using a 45 amp to only reproduce 350 to 2000Hz on a 100 dB/W driver in a 25m2 room and if average listening level is 85-90 dB SPL, would a 45 suffice or be driven to the point where 5th order harmonics become an issue?Al did an excellent job... | |
| Output threshold using a Dynaco ST-70 amplifier with passive pre. Regarding Q1: the lack of dual rectifiers in this amp results in the rectifier tube being the number 1 failure mode in the amp as far as tubes go, if the amplifier is routinely driven hard.There are not any good solutions- if you go solid state, u... | |
| Joule Electra preamps and amps. What is your impression? It is Michael Green Audio Revolution 80i free resonance speakers. I've not been able to find any information on this speaker, but in general it appears that the speakers on Michael Green's site are pretty tube-friendly in terms of impedance and ph... |
