| TL074 vs.TL084? @kakwu Generally speaking the older the opamp design, the less gain you can get out of it before it starts to have a 'sound'. Even with modern opamps the Gain Bandwidth Product they have makes it dicey asking for more than 20dB. With these older d... | |
| Finally Learned: Subs serve much larger role than adding more low bass Finally Learned: Subs serve much larger role than adding more low bass My GF commented on how the addition of the subs really helped out the tonal balance in the high end- how the system became more relaxed. | |
| ProAc Response 2: CJ CAV45, Cary SEI 300B, or Cary Rocket 88? @leahy back in the early 90s when that speaker was made we sold a lot of our M-60 amplifiers for use on them- it was the most popular speaker used with that amp at the time. That amp made/makes 60 watts. Unless you are really serious about low lev... | |
| Fancy Fuse for Regenerator? I'm seeking opinions if this is a great place because the benefits will go to all my equipment, or if it's a waste because the power is regenerated anyway. My prediction is that if you listen carefully you'll find no difference at all owing to... | |
| Suggestions for high efficiency speakers? Where are two Swarm subs positioned in relation to the CAL T-3's? One is placed against the wall (with the driver facing the wall) to my left. The other is behind me and to the right- it too has its driver facing the wall; in both cases to insu... | |
| Suggestions for high efficiency speakers? That was a bit elusive, yes. I tried to touch upon that using a sub setup the way I outlined as being my preference is a matter of having a different "design" goal - i.e.: high-passing the mains fairly high to a pair of subs, (the need for) symme... | |
| Dustcover Blues My problem is occuring just above the cutoff frequency. @mijostyn Filter theory says that the greater the filter slope, the greater the hump is prior to cutoff- and the closer to the cutoff frequency. A digital filter might behave differently (... | |
| Speakers for a Large Room (20’x37’) One other option, sort of off the beaten path is the Classic Audio Reproductions line. We've done ballrooms with the Classic Audio Loudspeakers T-1 and T-3. With that room size using those speakers I'd recommend 100 watts if you plan to crank i... | |
| A pitch too High! Why do you guys want me to buy a new Grado stylus. I'm was not suggesting any such thing. I misread the situation and had thought you got a different cartridge and thus solved the problem. Re-reading I see now that it was gauge instead. Eithe... | |
| Tube dampener questions I then purchased a 1960s d getter tube input/driver tube and the tube dampener became a moot point. The new tube sounded better and I don't feel the need to apply a dampener. Was I really hearing microphonics? I don't know but that tube is bac... | |
| RCA 9289 tube amplifiers I brought the amp up slow on a Variac and it passed sine wave. That's good! Don't keep running it until the power supply has been refurbished. Otherwise running it is a classic way that a failing filter capacitor causes a power transformer to ... | |
| Suggestions for high efficiency speakers? That's dangerously arrogant. You're not acknowledging the alternative, which is conspicuous in itself, and I doubt you've had a pair of symmetrically-to-the-mains placed horn subs or other efficient, large 6th order bandpass ditto (from a point o... | |
| A pitch too High! What should one look for? It should look nice and smooth like you see of photos of syli online. It sits on a little platform of sorts and should be perpendicular to it. Usually they are swaged or glued in. I'm thinking there may be an issue wit... | |
| Best Tube PreAmp - McIntosh vs. Audio Research vs. VAC vs. Atma-Sphere The MP1 is among the top 4 of my list. What's the life of various tubes in MP1, number of tubes/ models, and how expensive they're? Does certain tubes have to be replaced in set? @hitsofmisses None of the tubes are stressed so they last a lon... | |
| A pitch too High! @terrible +1 It might be interesting to look at the stylus of that Grado with a microscope. |
