| Cartridge Opinions - Sorry A gimbal set-up must always have some free-play in its bearings, otherwise the arm wand would be unable to move. This statement is false. If a bearing in a gimbal system is over-tightened the arm can still move but a lot depends on the bearing. A... | |
| Tube myths Not knowing the history, of the tube, it takes, a true emission tester, that the applied voltage, can be varied, and a working knowledge(experience) to determine, to any truthful degree, that a tube is NOS. Mutual conductance testing, is a grea... | |
| Not sure of term but I notice some distortion/vibration coming out the speaker port? Port noise is well known, especially with smaller speakers where bass signals too low for the port to be effective are present.It could be that the screws holding your drivers are loose, worth a check and see. But otherwise the speaker is simply b... | |
| Lots of bass at walls, lack of bass in center of room/listening position Lots of bass at walls, lack of bass in center of room/listening position@smodtactical This is the classic description of a standing wave in the room.While room treatment will help a little bit, its effect is marginal. You have two solutions both ... | |
| Eico ST-70 integrated amp The power amp circuit is a good design- enough so that others in high end audio make power amps that are the same circuit.If this amp is indeed stock, other than to see that it works, don't run it until the power supply filter capacitors have been... | |
| Cartridge Opinions - Sorry I do not know which Grado I ran back in the 80s. I do remember that the Pickering was a 4500. The Stanton was the 881. I got it next door at Sound of Music next to where I worked at the Allied Radio Shack. That is also where I bought my Technics S... | |
| Cartridge Opinions - Sorry In earlier threads on audiogon, when I asked about your MM cartridges, I never seen any top models even from Grado, AT, Pickering, Stanton or Shure mentioned in your answers. Yes- that's all true. But- this appears in contradiction toLow model ... | |
| 70’s rock pressings. Witch equipment deserve? Grado GOLD is relatively cheap cartridge, i like Grado too, but by reference Grado is Signature model from Joseph Grado (model XTZ). Yes, we’re running one of those in our shop turntable. No one would buy all those expensive vintage cartridges if ... | |
| Cartridge Opinions - Sorry Reading all these I want to remind that Ralph's experience with MM cartridges is very limited to certain mainstream models, I already asked about those models and never seen any serious MM in his list. @chakster pretty funny! just sort of an FYI... | |
| Phono Preamp. With transformer or fully active @intactaudio When I look at the specs of the 4722, it seems its bandwidth might be limited by the simple fact that it is meant to deal with a signal much stronger than that of a LOMC cartridge. Or it might simply be that Altec didn't intend the a... | |
| Phono Preamp. With transformer or fully active I chose the 4722 because it is a known device that represents the typical behavior of a microphone transformer pressed into SUT usage.18:1 seems like a lot of stepup to me, but at the same time I suspect that 4722 is intended for an input inducta... | |
| Cartridge Opinions - Sorry The Micro Benze did indeed work fine on my Graham 2.2. So did the Benz Ruby. But then it sounded even better on the Origin Live Conqueror. I found the Micro Benz worked better in my Triplanar as well. It was quite a trooper- I ran it for about 1... | |
| Dynaco ST 70 bias change Nothing is failing in the chassis- both sets of tubes run off of the same bias supply. You simply have power tubes that are getting weaker. | |
| Cartridge Opinions - Sorry Any one that owns an unipivoted tonearm design has very low knowledge levels on the tonearm/cartridge overall issue and you are not an exception to that.This sort of blanket statement is really problematic. The later Graham Phantom is a very dec... | |
| What's your "diminishing returns" preamp choice? @gochuchgo There are a number of single-ended 6SN7-based line stages I've seen that do the job. |
