| Passive & Tubed pre-amps to power amp at same time? PlanB: place the passive between the CDP and the preamp input.Adjust to suit, but keep your cables short as passives have been shown to be quite sensitive to cables! | |
| Output level inexplicably reduced- help Does this problem show up on all functions or only phono? | |
| Soundlab speakers...how reliable? If you picked up some used Sound Labs, check with Sound Lab about the new backpanels. They make the speaker a lot easier to drive and also sound better too! | |
| Need Advice on a Low End CD Player Giant Killer Oppo is a good recommendation. | |
| martin logan prodigy vs sound lab m-2 If you get used Sound Labs, make sure they have the new backpanel- they will sound better and are easier to drive. | |
| 6SN7 tube question FWIW we find the Tung-Sol tube to be just as unreliable as the EH tube. Both are made in the same plant and the big difference is the color of the base. | |
| RIAA vs Columbia vs Decca We have had a polarity reverse switch on our preamps going back to 1989. I find that it has no effect at all unless the recording is minimally miked. Then it becomes helpful- a lot easier than reversing the speaker cables on both amps! | |
| 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 ... |
