Preamp/Amp synergy with Cain Abby's?
Hi Restock, from what Paul told me the lacking sensitivity was the only problem. He loves the F-1 on his Fostex 1.3 speakers. Not sure if he tried parellel networks on the Fostex F200A. He was able drive the FTA with the mono ClariT but after inserting his BSC circuit . The monos started to clip badly. The BSC takes away some of the sensitivity of the driver in exchange for a flatter frequency response. The F1 maybe your best bet. If your planning to stay with speakers above 94dB. I just didn't want you to be stuck with it if you ever wanted to move to a different type of single driver. Not all of them are sensitive. Here's a French built amplifier which hasn't gotten a lot of press as yet. But from what I've read from some serious DIYers and underground audiophiles is a seriously great amp that may follow a design similar to the F-1.The difference being it will drive loads of 2 Ohms without breaking a sweat! I sent this info to 6moons, hoping they may review it soon. Profet amplifier. You can find out more about it on the Selectron forum. It sells for $1600 complete if I'm not mistaken. |
Also here's a little shootout with the Class T amplifiers. The Charlize looks like another good amp. You know me always looking off the beaten path. :-) As I've found IME the hidden gems are great finds. Cheers! |
I am going to be purchasing the Abby speakers and am also interested in what amp is best with them. I currently have all solid state equipment (Rotel) except for my headphone amps (Singlepower.) I am betting that tube amps would be better with the Cain & Cain speakers than solid state.... My situation is further complicated by the fact that my system has to do double-duty for both HT and 2 channel, as my house is much too small to have a dedicated listening room, let alone a separate HT room. Any thoughts on this? And where is your amp research taking you, Rene? After only 2 hours of listening to them at the seller's house, I love these speakers! Holly |
Restock, Sorry to be so late in responding. Somehow I missed your posting from several days ago. When I built my Moebius, I started out with the design just like Poindexter describes on his AudioTropic site, which is the same as the one reviewed in 6Moons. Terry Cain's Moebius is different, as I suspect he told you, in that it uses 6SN7 tubes instead of the 6AQ5/6005 tubes that Poindexter now prefers. Since I haven't heard the 6SN7 version, I have no idea how it would compare sonically. What I do know is that the "standard" Moebius with JAN Sylvania 6005 tubes sounds fast, detailed, coherent and powerful (an odd term for a preamp). It has amazing dynamics. For my tastes, the bass is a little lean, but that is easily tweaked through some tube and component changes. For example, right now, I'm using RCA 6005 tubes without any damping rings, a Noble volume control instead of the Alps Blue Velvet that the review unit had, and I made a few capacitor changes as well. These changes trade off some of the speed for a warmer tonal balance, but all of the positive qualities of the stock Moebius are still present. Incidentally, I think the 6Moons review is right on the money. It's a little short of the usual audiophile commentary, but what he says is definitely borne out by my experience. You can also read the same reviewer's report on the DeHavilland UltraVerve Jr. to get some additional perspective on the Moebius. I'm using the Moebius right now with Cary 40M monoblocks to drive Spendor SP100's. I recommend it highly! Dave |
