| Graham Phantom vs Triplaner I've been running the Tri-Planar for a few years now. The VTA tower (that allows for on-the-fly VTA adjustment) is much more precise than earlier models. I've had the ZYX and Transfiguration Orpheus; something that becomes apparent with these comb... | |
| Are passive preamps better? We have a cable industry in high end audio based on the experience of audiophiles hearing differences in the cables.However most audiophiles don't get that the recording/broadcast industry tackled this problem in the late 1940s and early 1950s, th... | |
| Are passive preamps better? Eldartford, 600 ohms may be tough, but not impossible. We developed a direct-coupled output, not unlike our power amps, to do the job. I think our MP-1 might one of the few preamps that can drive headphones directly as a result.Tbg, I've had direc... | |
| Are passive preamps better? Tbg, thus my final comment on my post!Several decades back, this problem was addressed by the recording/broadcast industry, for pretty much the same reasons that audiophiles deal with today. The result was the balanced line system, which is actual... | |
| Are passive preamps better? If I can speaker to some issues not previously addressed:There are four functions a line stage has. They are:1) supply any missing gain2) provide volume control and input selection3) provide buffering of the volume control from external impedances... | |
| Impressed with Tubes They don't seem to help if the impedance of the speaker is already eight ohms or more.That's kind of my point- the move to four ohm speakers which seemed to really gain steam in the 70s seems like it was not such a great idea after all.Labtec, I t... | |
| Impressed with Tubes Pubul57 and Phaelon, my comments about 4 ohms has little to do with the tube amp in question. 4 ohm taps on output transformers in general have less performance than the higher impedance taps, regardless of the size of the output transformer. Its ... | |
| Impressed with Tubes *In general* If you go with a tube amplifier you will find it smoother and more detailed than the best of transistors, if the speaker is compatible with the tube amplifier. This is because tubes obey the rules of human hearing to a much greater de... | |
| Valve Amplifier suited for my system If your speakers are 94 db, unless you are in a small room you might want to consider something with 30-60 watts, depending on your listening habits.My speakers are about 3 db more efficient than yours and I can run a 30 watt amplifier out of gas ... | |
| CAT JL-2 vs Tenor 75Wi Wp FWIW Avalons are a very linear load impedance and so larger tube amplifiers in general have no problem with them.The Watt/Puppy 5 has always been an easy load and is probably a little easier to drive from what I've seen, but its nice to have the e... | |
| Preamp/amp far superior to just int. amp.? The reason separates are usually preferred is that the integrated equipment often shares power supplies. This get to be a bigger deal when the power supplies operate both channels. Additionally, a great deal *more* care has to be paid to ground lo... | |
| Distortion from speakers - amp? Try swapping the input cables for your source and see if the problem moves. I was thinking the preamp because you mentioned that the volume control did not affect it, but if other gear behaves the same way there is something different afoot.I've s... | |
| Distortion from speakers - amp? OK :) I would try a set of shielded cables just to be safe. Unshielded cables, even balanced, can sometimes pick up noise. Otherwise I would guess that its in the preamp. If that's the case I would try moving the 6SN7 tubes from one channel to the... | |
| TriPlanar Tips HI Albert, I agree, backing up to take out the lash is a good move. There is just less of it now and more repeatable. The other thing that is really nice is the tower itself is a lot more precise, so there is less artifact from whether or not the ... | |
| Phono pre for 35mv cart that runs 6dj8 tubes?????? OK. 0.35mV then- you are going to have difficulty with a 6DJ8-based phono section. The problem that you run into is that 6DJ8s, 6922s and the like aren't designed for audio so you run into noise and microphonic issues which at the very least color... |
