| Phono Preamp. With transformer or fully active @intactaudio I don't see you commenting about the transformer loading in your post. I know that this bit is problematic: If you take a 2Ω cart and use a SUT designed for 40Ω, the LF extension will be down into and past record warp and tonearm res... | |
| Cartridge Opinions - Sorry The big deal you're going to find is that if the tonearm properly tracks the cartridge, then the choice of cartridge is far less important than people make it out. By 'properly track' I mean that no matter what is in the grooves, the music is alwa... | |
| Looking for tonearm inspiration The Triplanar is one of the most adjustable tonearms made. Its bearings are several grades harder than those used in the SME arms. So it has very low 'sticktion' as well.I operate a small LP mastering operation; the Triplanar is the only arm I've ... | |
| Tube Amps and Friendly Speakers - Back Impedance You may say, ... hey my amp is not supposed to be a tone control. Why should I settle for an amp whose output changes with FR and speaker impedance?One should keep in mind also that the human ear assigns a tonality to all forms of distortion. I... | |
| what is your opinion ? I run horn speakers and I've run SETs on them many times. But I prefer an OTL on them as it has obviously wider bandwidth, lower distortion, greater detail, etc. No going back. | |
| Solid states more accurate than tubes? Many people take the brightness of traditional solid state as detail but in fact most of the time its simply distortion. If the amp is truly low distortion at all frequencies then it will be more detailed but also relaxed.If we are talking about p... | |
| Solid states more accurate than tubes? The problem here is what solid state amp vs what tube amp.And this has everything to do with Gain Bandwidth Product, which is a factor that can limit how much feedback an amplifier has. For this reason, IMO traditional solid state amps are not mor... | |
| what is your opinion ? Altecs have controlled directivity in the mids and highs. Your panel speakers need to use the wall behind them to work properly- that needs to be about 5 feet minimum and you can’t have side walls too close or the reflections will mess with the so... | |
| Power Management Options:Opinions Solicited One thing you might want to consider is that if the Halcro preamp prefers to be plugged in directly into the wall, the conditioner that you compared it with is really not doing you any favors.You could have the outlets mounted on the floor rather ... | |
| Phono Preamp. With transformer or fully active With one SUT you can't use all MC cartridges, such phono stage is not universal for all MC. It will work for some of them nicely, but if your cartridge impedance is very low (2 Ohm) or very high (40 Ohm) you can't use one SUT for both of them. ... | |
| Quad ESL 57 with subwoofer @noromance You might also consider a set of Swarm subs from Audiokinesis.comThey will insure that you get 20Hz response, with bass evenly distributed throughout the room, since the Swarm system eliminates standing waves that might otherwise be pr... | |
| SET 45 and their (real) required speaker efficiency @vvcv A nice plan B to consider: If you are set on the type 45 power tube, why not get an amp that uses a pair in push-pull? I've done direct comparisons; the thing about any SET is that you really don't want to run them past about 20% of their t... | |
| Tube Amps and Friendly Speakers - Back Impedance But... I do understand... that they use SS amps to design and voice their speakers... so... I guess it would make sense to stick with SS. There's a big 'that depends' going on here. You really don't 'voice' a speaker to a particular amp (that is... | |
| MartinLogans and Cary CAD-805s / electrostats and SET amps Alternatively you can use a set of ZEROs (www.zeroimpedance.com) which will allow you to use a tube amplifier and the highs will be just fine.The high frequencies do not need a lot of power. but the overall sensitivity of this speaker is low enoug... | |
| SET 45 and their (real) required speaker efficiency A type 45 based amp is really only going to make about 0.75 watts or so unless you are using some kind of super-45 of which a few exist.My 45-based amp uses original RCA output tubes. My speakers are 98 dB and 16 ohms; very easy to drive but simpl... |
