| Better Amp for Cornwall IV's... If I can't hear the sound of my own natural speaking voice when the music is playing, I turn it down. I usually stay in the 90-95dB range on peaks. Loud but not TOO loud.This is probably wise. My measure of the quality of a system is that it d... | |
| Class D because of my obsession with GaN with it’s ability to have 1.5mhz switching speed the Achilles heel of Class-DThis really isn't correct. You can get vanishingly low distortion with less than half that speed; alternatively you can go a 1.5MHz using... | |
| Vfet / SIT Amplifiers I hope I was able to clear any misunderstanding.@sonetduo You did- I realized reading this that I had conflated some of your comments with that of another poster. I was addressing his comments, not yours, but with the idea that he was running the... | |
| Speaker sensitivity vs SQ These are field coil-fitted drivers, right? In that presumable case their price, though way above what needs to serve a fitting purpose here, makes a little more sense. @phusis They are TAD 1602s. Pricey, and a bit different from the EV. I forgo... | |
| Vfet / SIT Amplifiers @sonetduo I love the idea of a SIT-based preamp! The problem here is the Yamaha is far too complex. When you're dealing with purist amps and speakers (and let's be clear here- people these days that insist on crossover-less single-driver speaker t... | |
| 16 ohm speakers: any amp sounds better with more resolution. speaker cables less critical. Ralph, I am not sure what you are saying, because the terms "multimeter" and "DVM" are so often conflated with one another. VTVM is a clear acronym, because you are talking about a vacuum tube voltmeter. But let's take my Fluke 87 meter.If it... | |
| Still Need Help Wall mounts generally don't work all that well. To isolate a turntable from low frequencies you need a **non-resonant** mass beneath the turntable; to which the turntable is coupled with points.You use points to couple, so as to allow vibration to... | |
| Turn Table Cable Length @smccarthy This is a really Bad Idea! Here's why:The cartridge has an inductance. The tonearm cable has a capacitance. They are in parallel; when this is so an inductance and capacitance produce an electrical resonance. If its a MM cartridge the ... | |
| Acoustat Electrostatic spearkers I sold them, it wasn't until much later that a few guys figured out how to make the OTLs stable Uh yeah- that would be me... FWIW (one of Atma-Sphere's claim to fame was the first reliable OTL). Sure- just don't exceed the phase margin of the amp... | |
| Speaker sensitivity vs SQ Guys, it's simply not true to make a statement that a higher sensitivity speaker is more costly to make. Drivers, cabinet material, R&D, spikes, connectors, wire, glues, finishes.... and of course how many points dealers get to sell themLe... | |
| Vfet / SIT Amplifiers I have not tried anything else other than the Yamaha C-1, but I probably should@sonetduo Yes. Your Yamaha is outclassed by the amplifier. You might try a tube preamp; I think you'll hear a transformation. | |
| High end Class D amps? @mrdecibel What a class D amp potentially brings to the table is the ability to be neutral in a way that most solid state amps of traditional design cannot: they can be designed to lack brightness and harshness. For this reason alone they can work... | |
| Speaker sensitivity vs SQ My point is that dynamics are a matter of volume. A speaker that can hit 110dB without compression is going to be more dynamic than a speaker that can only get to 100 dB even if it is less. efficient. Just a matter of power. Horns are very dyna... | |
| High end Class D amps? Then next you lot may as well just tell us to use this 6000watt!!!!! Class-D Behringer for just $600us. Let me tell you, that on the Wilson Alexia in an a/b it was trounced by the 40 x times less powerful!!! Gryphon in dynamics and bass control.... | |
| Pure tube phono preamp So, it does not matters an all tube can’t mate those 3 phonolinepreamp targets. Today the best you can do for 10K is to go with SS. This statement is based on three anecdotal examples. This is a logical fallacy called 'Guilt by Association', wher... |
