| What are the best tube amps for Klipschorns? I can't imagine how a transistor amp could be preferred on a speaker like the Klipsch- unless one has never heard a decent tube amp! First off the Klipsch doesn't really play the bottom octave, so the idea that a tube amp would have less punch is ... | |
| Atma Sphere MP 3 pre-amp compared to FWIW I use a ZYX Universe with the MP-3, which has a 0.24mV output. This is the setup we used at RMAF so plenty of people got to hear it. The preamp is equipped with the regulator option. There is no appreciable noise and no need for a step-up dev... | |
| watts or joules? Watts. The output power of an amplifier is never specified in joules. Joules refers to the amount of energy storage that is in the filter capacitors of the power supply. Generally a higher number is better, but will not tell you much except in com... | |
| Need help understanding tube wpc In AC circuits there is often an inductive nature that can result in current lagging behind voltage. So it is true that current may not be peaked in all cases of loudspeaker; the more 'resistive' the speaker (i.e. magnetic planars, Avalon) the mor... | |
| Roger Sanders is back After having been through something that was frighteningly similar, I am very pleased to see that y'all have sorted things out and are back to give it another shot. Best of luck to you! | |
| Need help understanding tube wpc "After all, musical peaks are voltage driven, not current driven."In the world I live in, musical peaks being reproduced by a power amp produce power, not merely voltage. Voltage in a speaker cannot exist without current and this is inviably defin... | |
| Need help understanding tube wpc "The biggest problem with tubed gear is that it typically lacks current and is bandwidth limited, both on top and bottom. The lack of current is what gives most tubed gear that "round, tubby" bass that many folks dislike. At the same time, this "a... | |
| Whats more important? Speaker or the Amp I have to disagree with some of you here. If you have a great speaker, there is no way it will sound all that great if it exposes a poor amplifier. EX.: try putting a cheap transistor amp on a good horn system- you will regret it. Ex.: put a cheap... | |
| Whats more important? Speaker or the Amp There are two standards in place for speaker and amplifier design, and if you use an amplifier with a speaker of the other standard, or vice versa, you very likely will have an incompatability. This is not a matter of taste, nor is it a matter of ... | |
| Avantgarde Trios, SETs, and Impedance Curves A friend of mine was using the 45-based Kondo, which realistically makes about .75-1 watt. This ought to be enough on the Trio, but he was unable to run the amp so there was not a high frequency rolloff.The problem is that the midrange unit is not... | |
| Avantgarde Trios, SETs, and Impedance Curves The problem is that really low output impedance amplifiers don't sound right on highly reactive/high efficiency speakers (like most horns). There are interactions that result in shrillness. So a tube amp is indicated... | |
| Avantgarde Trios, SETs, and Impedance Curves The Trio is tricky to set up because the impedance curve is very unusual for a horn- high in the bass and low in the highs, due to the design of the crossover, which is mostly capacitors. A lot of SETs have difficulty with the speaker as a result.... | |
| Progressive Rock I use Porcupine Tree's Voyage 34 (the reissue sucks BTW) as a demo at CES and other audio shows that we do (like the recent RMAF). I also demo with ELP's first LP (pink Island edition...), Boards of Canada, Infinity Project (Mystical Experiences) ... | |
| A question regarding "tubes" Tubes have just as much bandwidth as transistors. The idea that tubes give up bass slam or anything like that is really nothing more than urban legend. | |
| Best AMP for Avalon Eidolon, ARC, CAT, VAC..? FWIW our customers report that the MA-2s are a nice combination with the Eidelons. In fact something like 95% of all the MA-2s built are running either Sound Labs or Eidelons. Based on this my feeling is that the Avalons are a tube friendly load a... |
