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... 
Hi efficient speaker, bass problems
Tmsorosk, it may be a language issue, but the appearance is that your post is in contradiction to the title of the thread. In addition, your post mentions low efficient speakers and then in the same sentence less sensitive unitsso its hard to know... 
Lightspeed Attenuator - Best Preamp Ever?
Clio09, I had the opportunity to compare the Lightspeed against one of our own preamps and I have to say it was the most neutral passive I have heard.Like any passive I have heard, it had less bass impact than the preamp, which as I have already m... 
DC issues using a Krell KSA 150 w/ tubed preamp?
Unsound, even if there was a tube failure, DC would not be the result. DC would be the result of a coupling capacitor failure, something highly unlikely in a tube preamp, as said cap would be a film type, which are very stable parts that last deca... 
DC issues using a Krell KSA 150 w/ tubed preamp?
There is no such thing as 'tube DC'. No preamp, tube or solid state, will make DC at its output if it is working right. IOW, the idea that tube preamps have DC at their output is a myth. 
Lightspeed Attenuator - Best Preamp Ever?
Digital volume controls have always been an irritant. As far as I am concerned, they are a failed concept. Given the brilliance of the Lightspeed system, it would seem a natural in a DAC or CDP. 
Lightspeed Attenuator - Best Preamp Ever?
Clio09 a low output impedance will mean that the preamp can drive a load of less than 1000 ohms without loss of bandwidth, voltage or increase in distortion. You don't need negative feedback to do that. In the old days, tube circuits did that with... 
How to accomodate a balanced only phono stage ?
Mordante, your best option in this case is to replace the junction box with one for XLR cables, and run everything balanced. The advantage of doing this is that the cables will have less overall effect on the sound- they will be more neutral. 
Lightspeed Attenuator - Best Preamp Ever?
Pubul57, there are 4 functions of a line stage:1) add any needed gain- not all sources are able to drive an amplifier to full output.2) provide for input and volume control- this function is shared by most passive and TVC systems.3) buffer the vol... 
Lightspeed Attenuator - Best Preamp Ever?
George has pointed to exactly what the problem is. In order to produce proper bass, there can be no phase shift above 20Hz. Fletcher-Monson has nothing to do with it. If it were F/M at the heart of this, the same loss of bass phenomena would be he...
