| Power Cords and Power Conditioner, How to arrange? I have a PS Audio Power Plant and I find that the power cord from the PS to my preamp and phono stage is the most important one. Intuitively, it could be explained that the power plant is fixing a signal fed to it, so why would the plant power cor... | |
| Tube amp speaker output 4 ohms VS 8 ohms No, you should not get any damage from connecting either output tap to your speakers, unless, of course, you send a clipped signal to your speakers or overdrive them. Yes, the sound will be different from both taps, especially if your speakers are... | |
| SME 20/2 & Graham Phantom issue Jaytea, I believe your description of your "SME" base is the same as the one I originally had. Yes, my newer "Graham" base was developed shortly after I had the SME base and yes, it is stationary. Since I did not have to change the holes in the pl... | |
| Amp suggestionsfor Wilson Watt Puppies/Sophia I forgot to mention that I heard a pair of Sophias driven by a VTL ST-150 amp at my dealer's and the sound was very impressive. Great soundstage, warm yet detailed, and you could pick out the bass drum and bass guitar in separate locations between... | |
| Amp suggestionsfor Wilson Watt Puppies/Sophia I had a pair of Sophias and now have a pair of WP7's. I tried a bunch of amps with both speakers, including OTL, SET, and push-pull tube amps, as well as some solid-state amps. I listen mainly to rock and jazz of all types and am in a small room. ... | |
| SME 20/2 & Graham Phantom issue I have this exact combo and mine works fine as set up by Brooks Berdan. However, I am not sure how Brooks did it. Actually, the first time I had the turntable set up using the SME mount the VTF knob did slightly hit the suspension o-rings when swi... | |
| Phono-pre I had a Michael Yee Audio PFE-1, which I think retails for about $900. Michael is the designer of the Musical Surroundings Phenomena and the newer Supernova. The PFE-1 has variable gain and load settings and can be configured for about 65dB of gai... | |
| worst 'long-lived' band I agree with Fatparrot above. The Stones were bad enough in their heyday in the 60's and early 70's--they did write some OK stuff--but later they have become almost comical. I read somewhere that after the early 70's they no longer wrote their tun... | |
| step up for mc There is an article in the September Sterophile by Art Dudley talking about transformer step-up devices for MC cartridges and how to select the optimal gain and loading for your particular cartridge. He discuss a relatively inexpensive unit from K... | |
| Tube amps Tube amps are usually not as good at handling low impedance speaker loads due to their high output impedances. A typical tube amp output impedance is about 0.5 to several ohms, while solid-state amps can have impedances down to 0.01 ohm, depending... | |
| Input voltage gain on levinson amps ? Hey, Arthur, nice job. | |
| Tube amps I agree with the other posters above. I have WP7's and while they are voltage efficient at 92 db/watt, they are a difficult load in the bass. I tried some 15 wpc SET Cary Audio amps and the bass was flaccid and the dynamic range was compressed. Ni... | |
| Input voltage gain on levinson amps ? The volume will be the same only if the voltage gain for the two amps is the same. However, even if the volume is the same, the two systems will sound different. If the systems are in different rooms this probably won't matter, but then neither wo... | |
| Input voltage gain on levinson amps ? What you need to know is either the voltage gain of the amp or the voltage needed to drive the amp to full output. You can then use the two formulas to figure out the gain: P=Vsquared/R and Gain=20log(V2/V1). | |
| efficiency- hope i spelt that wright. My Wilson Watt Puppy 7's have 92 dB efficiency, although at 4 ohms impedance they draw twice the current that one rated at 8 ohms would have. I tried some 15 wpc SET amps with them, and while they would drive them to reasonably satisfying sound le... |
