| The best coupling caps in power amp ?? Mundorf, Infinicap ?? Haven't yet tried the Duelund or Jupiter copper foils, but oh I so want to. I would try Clarity CMR for the most neutral and high value. I have issues with the fanciest Mundorf Supreme's. THey tend to scintillate, or hype up the mid to treble. It'... | |
| Why are the Infinity IRS, Reference 1b, Beta ect speakers passive on the mids and highs? Having seen a few fixes online, I have to say @timlub is most probably right.These crossovers were done very "empirically" and I doubt any designer with modern measurement and simulation tools today would arrive at the same crossover designs. Most... | |
| Surround Processor / Pre Amp / 3D Sound Field Hey Audoman,I use an Oppo 103 via a Halo P7 preamp. So essentially there is no real processing, but just decoding. Movies sound fantastic.However, what I spend a lot of time with is getting the subwoofer calibration correct and room acoustics. Thi... | |
| A speaker that looks like a driver or a driver that looks like a speaker? @timlub Thanks Tim! Yep. Baffle step issues are frequency domain, as I understand them, and must be dealt with in the crossover or via EQ. However, the wide baffles really seem to reduce early reflections, adding to transparency, which is usually ... | |
| Why are the Infinity IRS, Reference 1b, Beta ect speakers passive on the mids and highs? Partly aesthetics/market driven.Having this idea allowed buyers to use boutique tube amps for the mid/highs, letting them feel part of the process of creating the sound.Certainly when these speakers came out, no one wanted an all-active speaker in... | |
| A speaker that looks like a driver or a driver that looks like a speaker? I have read, but don’t remember why, that circular baffles are among the worst types of designs. However, having a very wide baffle is often a very good and under-appreciated thing. With a good crossover and high quality components this could soun... | |
| Anyone know what these are Thanks @grannyring I see it now.Ok, with more coffee and less fuzzy vision than I had yesterday (comes and goes) I can see most of the circuit. It seems that all parts are in parallel. However, 2 of the resistors are switching in or out, changing ... | |
| Anyone know what these are I don't see any capacitors involved. Since there is only one in and one out, it's safe to say the entire circuit is in series. Nothing shunts to ground. Therefore the circiut is something like this:0---vvv-vvv-vvv----uuuu----> with "vvv" repres... | |
| Anyone know what these are OK, so it's a little more complicated. It looks like there are 4 resistors, which I assume are in series with the coil. Not sure what the switch will do exactly. It could bypass everything, or just the resistors, or just the coil. Was this system ... | |
| Anyone know what these are Without being able to see all of it, it looks like a speaker level low pass filter, with a bypass switch. I can't tell if there are also resistors or caps involved. However, if it's just an inductor in series, that's what it is. Best,E | |
| Looking for a used AUDIOPHILE AV Receiver I heard an Arcam a couple of years ago, recently after auditioning Ayre and Audio Research.I have to say, I wouldn't be too upset if I had to trade all of my gear for one of them. Sounded really nice, close to the Ayre's darkness/quiet but also de... | |
| A speaker that looks like a driver or a driver that looks like a speaker? I think they are very interesting looking! But really decorator pieces. That is, you'd really have to consider the looks and aesthetics first, the sound second. I could see them in an ad agency screening room or some such. Best,E | |
| Make a trasnformer hum 101 Here is a good site for cabinet cooling, damping materials, etc.http://www.frozencpu.com/Best,E | |
| Make a trasnformer hum 101 No Idea. You may want to check out some of the panels they use for damping PC's. Best,E | |
| Make a trasnformer hum 101 There are also some cases when the transformer is actually silent, but the panels vibrate! Not sure I've come across anything like that in decades though. :) |
