| DIY balanced interconnects Tvad, what you are missing is the output impedance is not the spec. For example, the Modright might have a 100 ohm output impedance- if the output winding is designed to drive 600 ohms then it would work fine. Ditto Roland and Wadia. The output im... | |
| Cogent horns Macrojack, right now field coil drivers are custom affairs or at the least, pretty pricy. I know Classic Audio Loudspeakers modifies a certain JBL compression driver- seems to me by the time they are done there is very little left of the original ... | |
| DIY balanced interconnects Oldears, I don't think I've seen any cable wherein the barrel of the XLR was tied to anything. I would ignore that connection. The only ground you need to be concerned about is pin 1, which is always the shield at **both** ends of the cable.Tvad, ... | |
| DIY balanced interconnects Tvad, you got that right. I've not watched the solid state part of the market, but I know that Roland did support the 600 ohm standard. Generally its fairly easy for semiconductors. Wadia supported it in the old days- I've not kept up with them th... | |
| DIY balanced interconnects Oldears, connect the shield at both ends, which will always be pin 1. Any other connection (or lack of connection) is not standard and could cause troubles. The way it is supposed to work is that there will be no signal current in the ground- all ... | |
| Cogent horns Field coil speakers have always been more expensive to make. When permanent magnet speakers became available, the industry moved to them quite quickly due to the fact that they were cheaper. Like a lot of things in audio (tubes to transistors, LP ... | |
| Cogent horns Paulfolbrecht, the Classic Audio Loudspeakers model T-1 with the field coil drivers is about $52,000 for the pair. The T-3 set up the same way is about $36,000 for the pair.The reason field coils sound better is that they are like ESLs in the way ... | |
| 90db, 7ohm speakers: tube amp recommendations? Dawgcatching, most tube amps (including the M-60s) will drive that fine with no worries. | |
| A question of bass... Several actually. If you want a reasonable subwoofer approach, take a look at the SWARM by Audiokinesis, http://www.audiokinesis.com/ click on PlanetariumThis system obviates the usual room nodes and provides a seamless, extended natural bass. | |
| Why are most High End Amps class A Class A is the most linear mode of operation known. But- just like with anything high performance, is the exception rather than the rule, which is to say that AB amplifiers are far more common. On top of that, there can be so many compromises else... | |
| XLR interconnects? Hi Dave_b, of course geometry, the purity of materials and the like all effect the cable- until you have a termination resistance value that is low enough to swamp that stuff out.As audiophiles, we have been working with single-ended cables that u... | |
| A question of bass... Several actually. If you want to keep the mids and highs of the Primaluna, and still get respectable bass, you have to have a set of speakers that are designed to allow the amplifier to do just that.For more information on matching equipment seehttp://www.atma-sphe... | |
| XLR interconnects? Dave_b, I agree with you 100%. My point is simply that if you want to take advantage of what balanced line operation has to offer, you have to adhere to the balanced line standard to get it.Not doing so is very similar to running a high performanc... | |
| XLR interconnects? Lacee, this is a good portion of the reason that we saw several of those letters to Stereophile in the mid-90s from 'audio engineers', wherein the engineer was convinced that the high end audio market was composed of charlatans. In the letters, th... | |
| XLR interconnects? Hi Lacee, do I understand right that in your post above, the cable shootout was going on between the source and the preamp?The preamp is designed to support the balanced standard, but its inputs are high impedance to make it easier to drive. The r... |
