| Subsonic Rumble Solutions So I think I'm hearing what I kind of feared - that, given very good isolation, the final solution to subsonics lies in the signal path via a filter of some kind. I fear this because I would prefer to keep things as clean as possible. I fear this ... | |
| Subsonic Rumble Solutions Bob (Acoustat6) - it seems that we both use a Hagerman Trumpet. This is a great phonostage but we both seem to suffer from a subsonic problem using this unit.According to Jim H, he didn't limit bandwidth in any way, instead relying on the TT itsel... | |
| How to Bypass electrolytic caps Another suggestion that I learned while upgrading my amp some years ago. The bypass should be physically closer to the transistors in the amp. Technically the electrolytics are powering the transistors. So a small value film cap would do more good... | |
| Subsonic Rumble Solutions When I built it I was told that Corian is dense and fairly inert. It certainly is heavy (and pretty to look at), but I often question the same thing as you. I have toyed with the idea of applying a heavy piece of aluminum or some such to its botto... | |
| Subsonic Rumble Solutions Thanks for the link Fap. Is this filter available in a kit form, or just the schematic as provided? Where does it plug in, between the cartridge and phono stage or after the phono? I assume the whole signal rides through it ... if so then I assume... | |
| Subsonic Rumble Solutions Thanks for your suggestions, but I still think the problem is more inherent to the medium than my setup.My racks are about 200 lbs each. Each shelf is it's own seismic sink with 50 lbs of sand in them. They are spiked to a cement floor. My TT itse... | |
| Herron M1 Monos vs. McCormack DNA-225 Platinum? Oooh, I would love to hear this combo when you are done. I think the McCormack would pair very nicely with the tubed pre and the Cremona's.Enjoy,Bob | |
| Crossover designs... I would advise that, in addition to asking here, you check out the forums at www.Madisound.comThere are plenty of DIY speakerbuilders there, many quite knowledgeable, and all very helpful to beginners.Enjoy,Bob | |
| Are Dust Covers a MUST I just use a plastic printer cover over the whole TT when not in use, to keep the dust off. I think it was $3.99 on e-bay, for 2 (so I have a spare if this one rips in a couple of years - ha!).Bob | |
| Herbie Hancock, River: The Joni Letters This disk is utter crap. Mostly just Herbie noodling away and paying no attention to the melody. Most of the songs are unrecognizable as the originals. A real shame, given how good the originals are.Bob | |
| McCormack DNA .5 and 1- big difference? The .5 always had the reputation of being more refined than the 1. Yes, the 1 has more power, as does the 500. But unless you really need the power I think you would do better with a .5, most especially if you can get it to Rev A status. The rev A... | |
| Mapleshade Silclear I recently went over everything with acetate (nail polish remover), then alcohol and removed all my Silclear in the system. I then applied TVC and haven't looked back. I had it everywhere and never had a problem.Silclear has been very good to me o... | |
| Preamp for McCormack DNA-125 Gold? Budget $2k Get yourself a good, transparent tube preamp. There's a few of us here who run McCormack amps with Audio Prism Mantissa pre, or a Red Rose if you want to pay the name premium. Hard to find but they do come up for sale from time to time.There are c... | |
| Ultimate test of your system image When I first got this CD and played it I got up and looked out the livingroom window to find out what the neighbor's dog was barking about. It really sounded like it was coming from across the street.Fun CD. Gotta love Ambisonics for things like t... | |
| What is the one CD you can't find? When I come across a CD that I "NEEEED" and can't find it in the usual spots I look on www.GEMM.comI can usually find most anything there, CD and vinyl and tape. The rare ones can pack a pretty premium though.Enjoy,Bob |
