| At what distance are balanced XLR cables needed? Eldartford, FWIW our preamp has an output impedance much lower than 600 ohms. A lot of tube preamps do as well. The trick is: what is their output impedance at 20 Hz or 5Hz. With most tube preamps the output impedance at these frequencies will be ... | |
| At what distance are balanced XLR cables needed? The output impedance of a preamp has to be much power than 600 ohms in order to *drive* 600 ohms. Also, the output impedance at 5Hz should be the same as it is at 1KHz so there is no low frequency rolloff. You can see right away why most preamps w... | |
| Hi efficient speaker, bass problems Weseixas, you wrote: no one driver is going to go from 30-500+ hz IMO and still produce high sensitivity it would also produce 2 much distortion IMO.I guess I take issue with this. The TAD driver I mentioned does exactly this range quite easily, a... | |
| At what distance are balanced XLR cables needed? Kijanki, yes, I think I can. The purity of metal has a lot to do with 'diode effects' in the material. The idea is that strands of wire do not conduct completely linearly- they are affected by diode junctions that exist between them.However these ... | |
| Hi efficient speaker, bass problems Weseixas, that TAD driver I mentioned can cross over easily at 500Hz. So it can be matched with a horn midrange easily enough. I've seen some such horns have good response to 17KHz, although for what I want to call 'hifi' I would want to supplemen... | |
| Tube Monoblocks for heavy music on Khorns Stimbo22, most horns (Khorns included) have high efficiency drivers that, because of their efficiency, are also highly reactive. Such drivers have a lot of back EMF because of the greater precision and efficiency of their magnetic motors.The back ... | |
| At what distance are balanced XLR cables needed? If I can make some comments?To clarify, the balanced cable can run as long as you want it to and the cost of the cable will have no bearing on the sound if:The equipment supports the 600 ohm standard. If this is true you will not be able to hear a... | |
| Hi efficient speaker, bass problems Weseixas, TAD makes high compliance 15" drivers that have free air resonances in the 20s. At least one speaker, the Classic Audio Loudspeaker, has used these drivers to make a 3-way system that is good to 20Hz. It is rated at 97 db. | |
| Tube Monoblocks for heavy music on Khorns The complexity will kill the impact. With K-horns you want things as simple as possible. | |
| A Copernican View of the Turntable System Rauliruegas, in your prior post I am afraid that you lost me. I can't really make out what it is that you are trying to say. | |
| A Copernican View of the Turntable System Raul, yes, obviously if one boat is the LP and the other boat is the base of the arm, the motion between will be heard. Absolute rigidity between the LP surface and the cartridge body is paramount! That requires no slop in the arm or platter beari... | |
| A Copernican View of the Turntable System Pardon my arriving late in this discussion.If I can weigh in on something for a moment? I think Dertonarm and I are in agreement here: the coupling between the base of the arm and the platter of the 'table must be exact and profound. To that end, ... | |
| Amp for Sonus Faber Electa Amator The Electa Amator was always a great match with our M-60. The idea that they only work with transistors is not true at all. | |
| Lightspeed Attenuator - Best Preamp Ever? Having done some audition in this regard (we 'switched', if you will pardon the pun, to our custom Shallco part about 15 years ago as a result of some of these auditions), the difference in contacts that George is describing above is clearly audib... | |
| Maggies with Tubes? We have several customers that use our M-60s on Maggies, 1.6s and 1.7s. Since the M-60 is a small OTL, it does not handle 4 ohms well so they use a set of ZEROs and seem quite happy with the results (about 80 watts with this setup). Other than the... |
