| The future of preamps Audiolabyrinth, I think I need to clarify that. I think there are maybe 3-4 tube preamps with direct-coupled outputs (Berning made a hybrid called the TF-10 years ago, there was the Messenger and we make two of them. Pretty sure Krell was not talk... | |
| Warm, Smooth yet Transparent Amp Denon53, yes, I get accused of that occasionally :) | |
| The future of preamps Audiolabyrinth, despite what you quoted in the manual, that idea that somehow tube preamps have DC at their output is a myth! Most tube preamps have a coupling capacitor at their output and so cannot produce DC. I suspect that is something concoct... | |
| Tube preamp question :) you missed one, in a way the granddaddy of them all.The Atma-Sphere MP-1 was/is the world's first balanced line preamp, having been introduced in 1989. It is unusual in that it is also all-tube, but has a direct-coupled output, something unusua... | |
| The future of preamps I'm a bit confounded why it would be implicitly, and quite arrogantly assumed I'm not using my ears when stating the above; I most certainly base my findings on actual listening impressionsPhusis, I would guess that the reason is you have had a sp... | |
| Warm, Smooth yet Transparent Amp FWIW this is all about distortion. Solid state amps have a harshness due to trace amounts of odd ordered harmonics (5th and above) that the ear uses to sort out how loud a sound is. It is because of the latter fact that the human ear is very sensi... | |
| To Tube or not to Tube...... One of the more legendary guitar amps was made by Sunn, and was nothing more than a Dynaco MkIII. Looked a lot nicer than the Dynaco though :) | |
| tube amps and electrostatics ^^ Yup! We shown with Roy's speakers at audio shows in the past. Never had a problem with them. | |
| good preamp for dynaco mk3 monoblocks with maggies You could always find a used Dynaco PAS-3 and pay to have someone refurbish it. With some simple mods that preamp is a giant killer... | |
| The future of preamps another situation is that I cannot use typical tube pre-amps or sources direct to amp, or I would have to activate the coupling capacitors that are not active inside the amp to protect is from tube unstableness!Audiolabyrinth, best I can make out,... | |
| tube amps and electrostatics Impedance can be measured with a potentiometer of about 50 ohms or so, a signal generator and a DVM. It takes some time, as with this technique you have to put points on a graph.You put the pot in series with the speaker and drive the combo with t... | |
| The future of preamps Audiolabyrinth, Krell states that the gain of their amps is only about 25db. FWIW that is quite unusual (I had assumed their gain to be a more typical 30db), so in a high power amplifier you would indeed need more than 4 volts to full output. The ... | |
| tube amps and electrostatics The B&W 802D is, FWIW, an excellent example of Voltage Paradigm technology. The woofers are each 8 ohms, but also 3db less efficient than the 8 ohm mid range and tweeter. They are in parallel, which requires the amplifier to double its power i... | |
| The future of preamps Wadia is still very much around. Owned by the same company that owns ARC. They are a good example of why an analog preamp is handy- their volume control is an example of what I was talking about earlier.Audiolabyrinth, I can tell you with great co... | |
