| Is it good to drive the magnepan 3.6? I've got a similar setup with bridged Plinius (which run hot normally) for planar magnetics. No problem. Maggies are nearly a purely resistive load across the bandwidth. | |
| How to fix a lack of bass Null We haven't actually established it's a null yet. Download some test tones in the 50 Hz area you mentioned, copy it to a CD, not mp3. Play that and walk around the room. If the null is as big as you think, you should notice variations in volume, wi... | |
| Challenging Speaker Situation An unusual selection might be the pro-type Toa HX-5's with a sub. Probably the best speakers I've heard in a public setup. Each speaker is actually 4 hinged together and have versatile mounting options.What's your budget? | |
| shipping heavy amps - Canada to US? I think Canada Post has a limit of 30kg. UPS ground does not include brokerage fees but UPS air does. UPS also has a "dimensional weight" that can double the cost. | |
| Poll - Active vs. Passive preamp You should direct your questions to John Chapman on the AudioCircle/BentAudio forum or look at the older DIYAudio site. He will probably say that a buffer isn't necessary for most systems.If you could hear my system with a passive, there wouldn't ... | |
| recapping crossovers....do or don't? You could just use small bypass caps. | |
| Preamplifier power supply Must have been thinking about this interview.http://www.stereophile.com/interviews/222/ | |
| Preamplifier power supply There is some talk about this subject on the PSAudio site that's fairly amusing.Shadorne: My preconceptions were the same as yours. Techies have a hard time with that one. | |
| Your combination:AC isolation/condition devices Any dual core, 480/240-240/120 transformer can be wired (creatively) for balanced AC output because the secondarys are out of phase. Pretty much everything over 1KVA is dual core. If you wire 240V to the 480 primarys(H1-H4), you get +/-60V (refere... | |
| Your combination:AC isolation/condition devices Before you start looking that up, common mode refers from line or neutral to ground and "differential" or transverse or normal mode refers to noise between line and neutral. Common mode is the big culprit. A shielded transformer is also a capaciti... | |
| List : Components with high dynamics No names, but feeding kilowatts to 90+ dB line sources seems pretty dynamic, when needed. | |
| Anyone ever tried 2x100Watt Bi-Amp Vs 200 Watt Done both bridging (Plinius SA100's) and passive biamping. In the latter, I used Monarchy SE100's above 90 Hz and an old Mission 777 (100W) for bass, along with a custom attenuator to accommodate gain differences. This setup took advantage of both... | |
| Battery Powered Preamps The first battery powered preamp, the Mission 776, used two 12 volt lead-acid in series. Those type of batteries are still used in emergency lighting and are not expensive. Dynamics was not an issue. I only had to replace the batteries once in 6 y... | |
