| Requirements for Moving Coil setup Most moving coil cartridges are low complianceFurther, many LOMC cartridges are high compliance as well. I would like to use the MM cartridge (Grado Blue) on my BIC 960 as a 'preview' turntable for 2nd hand vinyl recordings. The JVC QL-A2 would ... | |
| Substitute for Shindo in the UK We just got a new dealer in the UK and our gear carries the CE mark. Shindo should be exempt from many of the directives (as long as no digital or computer circuits are involved), and its possible to self-certify. This should be solvable! | |
| Do you have a favorite vacuum tube? The Amperex 7316 is one of the best 12AU7s out there.6SN7s are better than that though. 12AU7s, 6CG7s (also excellent) and 12BH7s are all based on 6SN7s (the 6CG7 and 12BH7 are literally 6SN7s in a miniature envelope; the 12AU7 is the same geometr... | |
| Replacing my MFA Luminescence B2 preamp Regarding the power supply, what should I be looking out for.Older filter capacitors that need replacement. If they fail, they can take the power transformer with them, which is tragic, since a part like that can be really tricky and expensive to ... | |
| Help with XLR between Luxman L-509X & Hegel HD30 DAC To be clear, the American standard is pin 1 ground, pin 2 **noninverting**, pin 3 **inverting**.There is no 'cold' and 'hot'; both signal pins carry equal importance.The Euro standard reverses the phase- the assignments of pins 2 and 3 are reverse... | |
| Best Loudspeakers for Rich Timbre? @dracule1I think you might be glossing over my comments here.All amps, tube, solid state and class D, make more distortion driving lower impedances. Its a simple physical fact- you can see it in the specs.Its also a fact that the human ear convert... | |
| Clipping triode or ultralinear Damaging a tweeter by clipping is far more common with underpowered solid state amps than tube!Unless you can state that you fried the tweeter using a tube amp, I wouldn't worry about it, but to answer the question directly, the above responses ar... | |
| which Audio Research pre-amp? A reasonable question a-s, the answer being ARC pre-amps have a certain cache' amongst audiophiles. My question is, why doesn't the op audition both the ARC pre's he is interested in at an ARC dealer? Doesn't trust his own judgment, but "knows"... | |
| Replacing my MFA Luminescence B2 preamp I can't think of why you would want to change out the MFA for a Coincident. They aren't built to the same scale. The tricky bit is that the Luminescence uses octal base tubes in the phono section, which are a bit difficult to get (6SL7s). If its p... | |
| balanced vs. unbalanced sound quality I'm guessing Johnson was referring to the signal path length within a balanced circuit, not within a balanced cable.Often the signal path within a balanced circuit is simpler. At least that is the case in our stuff. For example, in our preamps the... | |
| Krell Owners: Is XLR really superior to RCA? Also I’d read that the quality of cable was less important for balanced than single ended, but that’s not what I’ve found. Cheap cable is still cheap cable. Tried some off the shelf stuff and it was flat and un-engaging. Currently running Mogam... | |
| Atma-Sphere in CO? while we can test the tubes, that may not really give you the information you are looking for, we can test to see if it is working, and get some idea of the condition but this won't tell how it sounds or how much use they have had. In addition,... | |
| which Audio Research pre-amp? ?? Why does it have to be ARC? Is that the only preamp that will allow marital harmony?The Ayre has a balanced input, so a balanced tube preamp seems to be what you are after. FWIW, the ARC preamps while balanced, don't actually support the balanc... | |
| Problem related to Push-Pull or EL34? Tube amps with output impedances greater than 1 ohm will not have a flat response into a speaker's varying impedance. They will act as tone controls! So, choose your tube amp/speakers with this consideration in mind!While this is off topic, the... | |
| Converting stereo single ended to balanced mono? You could do this with some modification, but there really isn't a good way to do it otherwise. The problem is that you have to invert the signal to one channel in order for a balanced output to be produced from the pair of channels.One way do sol... |
