| Recommendations for MM Phono ~ Tube or Solid State In fact, the bipolar transistor that Raul et al use in the MC gain stage is out of production and was not replaced by anything as good or better for the purpose, probably because transistor evolution is not motivated by the design and build of ph... | |
| 300B Tube Amps with 15/16 Watts Per Channel? my speakers Cube Audio Nenuphar is a single wide band driver. The manufacturer recommends amps with 0 or low feedback design, which will also have low damping factor. @debjit_g Here are some more things to think about. I’ve worked a lot with s... | |
| 300B Tube Amps with 15/16 Watts Per Channel? For everyone here who is considering a zero feedback 300b amplifier, something you should know which has to do with the loudspeakers you plan to use: http://www.atma-sphere.com/en/resources-paradigms-in-amplifier-design.html The short explanation... | |
| Can anyone tell me when XLR connections were first used on stereo equipment. (what years)? @coltrane1 Yes- they built a nice company. They were several years after the next company we found after us to be making balanced line equipment; Jeff Rowland. IIRC their balanced preamp showed up about 1991. | |
| Spatial Audio Raven Preamp @lynn_olson DACs are quite different from actual class D amps- the latter draw considerably more power. DACs OTOH do not- and have internal regulation. onboard with the DAC. So different kettle of fish. There are inexpensive (less than $200 or ev... | |
| Can anyone tell me when XLR connections were first used on stereo equipment. (what years)? @coltrane1 Yes. He had an in law that lived a block from me. Steve had two sets of our MA-1s and one of the first production MP-1 preamps. He was a friend of Victor, who called me one day saying the simulation he was running of the MA-1s didn't wo... | |
| Where does music come from that streams? How do I know his choices are as good as mine? Is there a new hierarchy in hi-fi now? Is streaming as a method reproduces the cleanest sound, as opposed to playing a CD, SACD, LP, tape through your own equipment? @drjjpdc There's really no good... | |
| Does Anyone Know the History of the Early Sota Turntables? There was a bass extender module for them, which this pair has. Makes them look like Wilsons or those LS3/5A with their bass modules. Has a 7" Focal woofer in each cabinet as I recall. @neonknight Yes- no that you mention it, we had that at CE... | |
| Does Anyone Know the History of the Early Sota Turntables? @neonknight That was a long time ago! It was not a large speaker though and IIRC was a 2-way. | |
| Does Anyone Know the History of the Early Sota Turntables? One interesting tidbit in this letter is the mention of the Panorama speakers SOTA released. There is an ad out there for a pair of the speakers on the other side of my state, and they have been listed for quite a while. If I were a collector the... | |
| DeVore O/93 or PureAudioProject Duet15 for a First Watt SIT-3? @ulul 18 Watts (or 30 into 4 Ohms) isn't a great deal of power. From the looks of the distortion curve vs power, if you want the most out of this amp it really should be loafing. I think it will sound fine with any of the speakers you mention, but... | |
| Spatial Audio Raven Preamp Yes, the requirements for the input/buffer stage are actually quite modest, not even a headphone amp, really. But the current fad for floating 12 or 15V supplies from a switching wall wart limits the output swing and current available. Barely e... | |
| Looking for phono preamp advice in the $1000 - $1600 range @bimmerlover Your power amp is balanced. Your existing line stage can't take advantage of everything the amp (or interconnect cables) have to offer as a result. There are balanced tube preamps that also have a balanced phono section that can tick... | |
| Reasonably priced preamplifier @gopaljeen If you were thinking of something capable of balanced operation, keep in mind that not all 'high end audio' preamps that are balanced actually support the balanced line standard (AKA AES48). It is that standard that allows the interconn... | |
| Suggestions for phono preamp for LOMC's Do you equate the resonance frequency generated by the inductance of the cartridge being in parallel with the capacitance at the inputs with RFI? @lewm Yes, since it is commonly at MHz frequencies. Hard to put it as anything else! |
