| 6SN7 tube question There are three kinds of 6SN7s: GTs, GTAs and GTBs. If the circuit needs one of the latter two and you have been installing GTs, they won't last very long. GTs don't handle as much voltage.We've been recommending Andy for decades- he is an excelle... | |
| RIAA vs Columbia vs Decca Phase shift is removed by the act of equalizing. It was put there by the pre-emphasis network during the mastering process. So when you play it back its removed.Vintageaxeman, The curves referred to in this thread are an urban myth, other than the... | |
| How an audio rack can enhance your amp/pre Discwasher made an anti-vibration damping platform in the 1970s. Ampex recognized that vibration was a problem in the late 1950s and esoterically mounted their circuit boards in their 351 electronics as a result. I saw the first Sound Anchor stand... | |
| looking at upgrading my tonearm from a triplanar Audiotomb did you try any of the newer Triplanars? The new 12" is pretty impressive. | |
| Liquid Midrange' - strong side of which tube amps? If you want liquid midrange nothing tops triodes...Getting power from triodes is an issue though but much depends on the implementation of the amplifier. So far there has been no mention of the speakers used which will play a big role in this. The... | |
| stereo preamp $2-5K suggestions If looking at tube preamps, make sure that they are comfortable with the input impedance of your amp. We just introduced a tube preamp in this price range and FWIW its OK with that impedance.However I agree with others here- make sure your system ... | |
| Woofer pumping WHY?? My phono section has bandwidth to 2 Hz but I don't experience excess woofer motion. A lot has to do with the match of the arm and cartridge.But making sure the turntable (especially if it has no suspension) is properly isolated and also does not h... | |
| CJ PV-2ar or PV-7 or ARC SP-6 for Klipsch Heresy? A cj might have too much gain to use with high efficiency loudspeakers. But to say that the noise floor of tubes in general is too high for speakers of 100 db or more is untrue. The proof of this of course is that most horn speakers are used with ... | |
| Joule Electra We can do service if that helps. | |
| RIAA vs Columbia vs Decca Chakster, I can't agree with you on the above statement. The reason why is the labels did not choose the EQ curve. The manufacturer of the cutterhead electronics did. For example we use the Westerex 3D cutterhead and the 1700 electronics. The EQ c... | |
| What's your "diminishing returns" preamp choice? Both! You can't see the forest through the trees?These are both in reference to a source with a weak tube output stage, geeeeish!!And don't even come into play if the source has a good low solid state output impedance.I can see forests pretty well... | |
| How an audio rack can enhance your amp/pre however we do Not agree with your comment “proven effective for the past 6 decades”. If you are implying ‘sixty years’ of vibration management in audio;To the best of our knowledge:Audio Points was the second ever conical shaped product in the aud... | |
| TUBE AMP LOVERS - What SS amp makes you smile??? ^^ yes we say funny things because we have a sense of humor. | |
| CJ PV-2ar or PV-7 or ARC SP-6 for Klipsch Heresy? If an original set, you really want to think about a tube amp too- the crossovers in that speaker don't work so well with amps with a low output impedance- as a result the horns can be operating out of band, part of the reason for the 'shoutiness'... | |
| What's your "diminishing returns" preamp choice? In fact passives are usually better if they are full up, as there is less shunt resistance to ground, so the source (if a weak tube output) sees an even easier load, which equals better dynamics for them. Passives sound just the same down low as t... |
