| Turntable upgrade recommendations: SME vs AMG vs Technics vs other I find the impressions of the OP's friend to be quite plausible. In the signal path, every active device increases noise, and every reactance creates phase shift. | |
| How important is the cable between the SUT and phono pre? @jpjones3318 Don't know if this will help, but resistance is a DC measurement in Real Numbers, while impedance is an AC measurement in Complex Numbers. Capacitance and inductance both have non-zero imaginary components, and analysis in this doma... | |
| Room Ceiling Height for 2 channel listening - is taller always better? @dodgealum I took advice from the marketing dept of Queietrock - and found myself talking to a senior executive with technical knowledge. Be sure to tell them what you want - sound quality inside the room, or quiet outside. Also, how intrusive ... | |
| Turntable upgrade recommendations: SME vs AMG vs Technics vs other "preferably with a member of the opposite sex sitting in the passenger seat. " PASSENGER SEAT? Baby you're so square! | |
| Magico A5, Wilson SabrinaX, or PS Audio FR30? I assume that you've tried planar and don't like them. But if not, the big Magnepans would be worth a listen. | |
| Room Ceiling Height for 2 channel listening - is taller always better? @ronboco Above is also intended for you. | |
| Room Ceiling Height for 2 channel listening - is taller always better? @dodgealum Glue and screw. No nails. Elastomeric glue - it never quite dries, always flexes, but very slightly. Chemlink makes good ones - I used 2 cartons of BuildSecure and 12 cartons of M1, IIRC. Quietrock 545. I backed mine with 3/4" Baltic... | |
| Room Ceiling Height for 2 channel listening - is taller always better? Room height must be balanced with length and width, but the golden ratio is not the way. The science has been done at the School of Acoustics, University of Salford. They ran a hundred thousand simulations and found that most rooms are bad, a thi... | |
| Turntable upgrade recommendations: SME vs AMG vs Technics vs other It's a good idea to buy your analogue front end from one place, so that they can set it up properly. Unless, of course, you are already an adept. IMO | |
| Not manufactured any more. @skyscraper I have several sets of Chinese Quads. Fit and finish is good, not German, but good. Components are average, beginning to fail at 15 years. Just in case you are still interested. | |
| Turntable upgrade recommendations: SME vs AMG vs Technics vs other Agreed, the compressor must be in another room. Disagreed about intrinsic noise of the air bearing. Empirically speaking, the higher end Nottingham Analogue (improved to Dais specification and anti-resonance plinth) does not compete with the air b... | |
| Turntable upgrade recommendations: SME vs AMG vs Technics vs other @lewm "The trick is to minimize the noise while realizing the gain." Completely agree. Obviously active devices are essential. My phono/pre uses three stages of them. My point was this: "Why introduce a host of active devices to reduce pops an... | |
| Turntable upgrade recommendations: SME vs AMG vs Technics vs other @lewm "Could be you are saying that to couple a low torque motor with a heavy platter is a good thing, because speed in such a design is primarily maintained by the rotational inertia of the heavy platter. " YES. In my rig, the platter must be ... | |
| Turntable upgrade recommendations: SME vs AMG vs Technics vs other @lewm Agree with almost everything. But: a low torque motor (e.g. 2W - yeah, I know watts are joules/sec) simply lacks the torque to affect speed very much. It's barely enough to overcome stylus friction and belt flexion, so it's tiny irregular ... | |
| Turntable upgrade recommendations: SME vs AMG vs Technics vs other @mijostyn "with modern machining bearing tolerances can be very close to perfect" Agreed. It’s the "close to" that tells the story. In the old days, bearings were machined fairly closely, and then rotated against each other in situ, with fine g... |
