| what to buy first mhsmith What should be purchased first? Speakers first pick the ones you like the sound of first in good Audio shops, as most shops will have them driven an amp that does them justice, as speakers can be hard or easy to drive.Once you’ve got the ... | |
| Lowering the noise floor Proper grounding is another way to lower the noise floor. That’s a given for LF hum, but for HF noise it’s a bit more complex.Cheers George | |
| Lowering the noise floor gdhal Wouldn’t that be a moot point if one is using an integrated amp? The OP tommylion uses a 2A3 poweramp with an input impedance of 100kohm and very high gain at just 500mV input for full wattage output. There is 2000mV (2v) or more available ... | |
| Lowering the noise floor If your active preamp is a "large source of noise," you really need a better preamp. Why, if you go passive (no noise) and you have more than enough gain without an active pream in 90% of systems. Even the "best" active preamps add their own no... | |
| Lowering the noise floor tommylion "Lowering the noise floor"90% of systems these days have enough gain from the source and in the poweramp so a passive pre can be used, this get’s rid of a large source of noise, the "active preamp".Remember what nelson pass said: Nelson ... | |
| My apologies_Upgrade path from Wilson WattPuppy 7's? Below is the lab test done on the Yvette’s, although not as current hungry as the 7’s it still needs an amp with current if you want to get the best from them as the 1.5ohms at 65hz indicates . "which makes the Yvette a more than averagely chall... | |
| Which watts are the right watts in SS amps? The good watts are pretty much always the clean ones Correct, you need good watts, but also good current to back them up, otherwise you end up with a "tone control" instead a of an amp that trys to remain dead flat into varying impedance's.Chee... | |
| Which watts are the right watts in SS amps? The more I’ve dug into amp designs and uses the less important watts seem to be. Correct, you just have to listen to a pair old well serviced huge Class-A Mark Levinson ML-2 monoblocks, these were only 25w!!!! into 8ohms, yet could almost double... | |
| DACs and bass response? Looking at the inside of the Aqua La Voce, it’s looks to me as it has a capacitor coupled output stage, as many owners are doing cap change mods to it. Being an opamp based output stage on it from what I saw, it is very possible with a tech who kn... | |
| Which watts are the right watts in SS amps? Do you know if the Sabrinas and later model Sash’s have similar IMP traces as the Wilson’s you just mentioned here? Both are hard to drive, not quite as bad as the Alexia, but both to sound at their very best in the bass would need an amp with go... | |
| Which watts are the right watts in SS amps? Combine hard to drive speakers with most tube amps and you have a response that is all over the place. Yeah EQ'd to the sh**-***se, some call this tube sound or euphonic's. I call it an equaliser.Cheers George | |
| Which watts are the right watts in SS amps? good engineering demands speakers that are easy to drive This would be great, maybe in the future with different construction techniques, motor design, materials ect, but for now easy to drive speakers usually have other permanent compromises, th... | |
| Which watts are the right watts in SS amps? It's useless to talk about 4ohm speaker and 8ohm speaker, as none are flat at that impedance across the audio band, they are very different. And the best way to treat it is to look at the lowest impedance and - phase angle and base an amp around t... | |
| Which watts are the right watts in SS amps? I've NEVER seen a speaker company provide charts of impedance magnitude or phase angle. You couldn't trust them anyway, only independent testers like Stereophile and the Miller Audio Research Company (you have to join), give you "unbiased test ... | |
| Which watts are the right watts in SS amps? When it comes to the perfect amp, Ralphs OTL Atamsphere’s are it. But, and it’s a big BUT, you need the perfect speaker. One that is efficient, has a nice even resistive high impedance load across the frequency range, with virtually zero phase shi... |
