I thought it would be a good idea to have a thread where folks could describe their current SD systems, what they've had in the past, and if they aren't somehow fully satisfied with the current system :d, what they might do in the future.I'm going to start by admitting right here in front of everybody that I don't currently have a system with a single driver speaker. Terrible, I know, but it's just a matter of time and money before I'm back in the swing, but I have to get all my sources set first.What I've had in the past? 3 different speakers, all of which had their strengths and weaknesses, a variety of amps, and front ends. I also had a sub (TbBI) for a while. My first setup was a pair of Horn Shoppe Horns with the old Sigma 108e driver which spent most of their time being driven by a set of ASL Wave-8 8 watt PP monoblocks (though I also tried larger SE, PP, and a tripath amp with them.) This speaker was the hands-down winner for detail and transparency, but for my tastes needed a sub to fill in the bottom end -- and that ended up taking some of the magic away. Even when that was working at it's best though (when driven by a 40 watt, single-ended Golden Tube Audio SE-40) there was still a cabinet resonance around 200 Hz or so that I just couldn't get used to. Also, because of the way the room was configured, I had pretty much the exact opposite of corners -- a large obstruction in the middle with the speakers on either side of it, and lots of open space on either side (with the nearest wall being about 7 feet away, and the other, 15 feet), and these speakers just didn't work well in that situation.I then got a pair of Abbys, which were much better suited to the room and my listening tastes. These were my favorite overall, though not with some caveats. These too were driven by Wave-8s initially, an Audio Note Kit1 300B 8 watt SE amp, the Golden Tube Audio amp, a Sophia Baby, a Sophia el-34 PP integrated, and eventually a fully modded RWA Clari-T. To my ears these speakers had the best overal tonal balance, the best bottom end, and a generally very smoothe midrange with very decent transparency, excellent dynamic response, and just plain listenable. On the negative side, they really tended to shout at you, especially with female vocals, and the sweet spot was considerably narrower than with the Horns. Still, it was a sad day when I sold them, but if I had the room and could afford to keep them, they'd still be here.The last pair was the Omega Revolutions -- a Visaton B-200 driver in a Snell proportion cabinet with an aperiodic alignment. I liked these speakers a lot with the RWA Signature 70s, but bass was a little thin and the upper mids and top end (which was, I think better than all the others, but since it had been so long since I had the Horns, it's hard to say that with any authority) was a bit too hot for my liking. I had the drivers modded by Planet 10-hifi (which I highly recommend) and that tamed them a bit, smoothed things out in the mids and top end, and greatly increased the dispersion so there was less beaming of the high frequencies. Then when I tried it with an 8 watt PP 6BM8 amp, the bass was all but lost, and since I then had them in the near field, they were just too hot to listen to. Then an unexpected financial situation forced me to sell off my entire office system, and that ended the first 3 chapters of my single driver speaker adventure.Now, a few things have changed and I now once again have an opportunity to build a minimal system in my office, and the front runner for this is Roger Modjeski's 13EM7 amp, possibly the preamp, and the little model 103 speakers, plus my squeezebox and a USB DAC of some sort. Maybe a small sub will be worked into that at some point too -- I'll just have to see how much room/money is available, plus there may be a very cool, desktop sub coming out from another company, but there's no timetable on that yet.So that's where I've been, and where I'm going. As for what's here now -- a pair of Adagios and a Cayin 55 watt KT-88 PP integrated, which is all in the living room -- and a little setup in the bedroom consisting of a pair of AV123 X-LSs, a 27" Toshiba TV, a Denon 2910 (stock) and soon to arrive, an Onkyo 8222 receiver.So, where's everbody on their respective single driver journeys?-- Jim
Chad,When you feel like you're ready for that EL34 tube amp, check out a Dynaco ST-70, or clone. It's just a power amp -- not an integrated, and when rebuilt with a better power transformer, filter capacitors for the power supply, and improved driver boards -- as are available from Van Alstine, Mapletree audio, and Welborne Labs to name a few (the Welborne is an entire new new amp on a PC board and can use 6550s as well as EL34s, and fits in the standard Dynaco chassis.) I'm pretty sure Louis has one variant of the ST-70 in his shop, and loves them with the XRS.Thanks,Jim
Every Fostex guy I know says you have to get a phase plug in there.
