| What is the single best pre amp you have ever hear The best I have heard so far is our own, but of course I should be expected to say that. I like it because there are no coupling caps at the output, unusual in a tube preamp. This makes it very fast with very deep bass. Other preamps that I also l... | |
| Amp and speaker matching. That is understandable. Dynaudio loudspeakers are designed for transistors. Its hard to make them sound right with tubes. | |
| Capacitor Size Your technician was on the level. Its a general rule of thumb that electrolytic capacitors (the kind found in power supplies) decrease in size in newer versions. It was that way in the 1970s and is still true today. | |
| Lazarus Audio any Schematics Anyone? The preamp was based on a modified Dynaco PAS-3 without tone controls that was published in an old Glass Audio magazine. | |
| Solid State for Rock and Tubes for Jazz, Yes or No Yes, 'tight' bass will be 'better' with higher damping. The issue is, best I can make out, is that 'tight' bass does not exist in the real world. Its seems to be an artifact of stereos. If you have ever turned up the volume seeking more impact the... | |
| Passive Pre-amp: Improves overall sound quality?? Brownsfan, I think I agree with you; I have seen this, but really I used that example to make the point but it was also something I had experienced (BTW the person that had those cables was ecstatic that he was able to sell them and actually have ... | |
| Balanced or Not Al, I think I know a better way than that, but it requires a mod to the amplifier. But it is a very simple mod!Any amplifying device (tube or transistor) has two inputs. On a tube this would be the grid or the cathode. Taking that a step further, ... | |
| Best Electrostatic loudspeaker? Best Electrostatic ?!?!Yes. The very best. Made by Sound Lab. Why is it the best? Its the one that plays the deepest bass and has the greatest dynamic range. That is why- otherwise, Quads, ML, etc. are all quite convincing (and excellent IMO) due ... | |
| Solid State for Rock and Tubes for Jazz, Yes or No Mapman, I don't know how many times I have dropped this link but here it is:http://www.atma-sphere.com/Resources/Paradigms_in_Amplifier_Design.phpIn short, damping factor has little to do with getting bass, in fact if you have too much that is wor... | |
| Passive Pre-amp: Improves overall sound quality?? Lets list what a preamp does:1. source selection2. voltage gain3. attenuation4. buffering (impedance matching)5. tone control (older preamps,typically)Let's get rid of #5 for now- passives don't have them, most good line stages don't either.To tha... | |
| Dielectric grease and tubes There should be no arcing on any tube socket if it is in good condition and no grease is needed. Some sockets can be damaged by arcing caused by a failure of the tube, if this happens the grease will not protect anything. | |
| How to get the impact of a live concert? Wolf, the SPL meter would probably work fine, just place it near the speaker so you don't have to run huge volumes. If you are really intent in this borrowing a sine/square generator should not be that tricky.BTW, a sine generator does not do this... | |
| Recommendations for Speakers that sound like Snell No-one has mentioned the B yet, which was also an impressive speaker. With 22 Hz response, it could shake the walls, and with its obliquely aimed rear-firing tweeter it imaged quite well. It was easier to drive than the AIII was, I thought it soun... | |
| Passive Pre-amp: Improves overall sound quality?? Yes a lot has been written about the passive/active debate.In a nutshell, the math (on which all electronics is based) goes against you when you run a passive system. The Lightspeed is no exception. You can improve the situation slightly by using ... | |
| Solid State for Rock and Tubes for Jazz, Yes or No If the tube amp is happy with the load, IME you won't find a transistor amp with more slam. You don't need a super low output impedance to control 15" woofers either! Its all about how the amp interfaces with the load.more:http://www.atma-sphere.c... |
