    A bit more info, based on my experiences with it.

    The 912's main features are its flexibility and ease of use, with all adjustments being easily accessed from the front panel. In addition to multiple line level inputs and outputs, it also has the capability to accomodate signals from two vinyl sources, and easily matches with any cartridge you care to use. In fact, the phonostage in this is one of the best out there. The mm section is truly excellent, with plenty of gain and massive headroom, enabling matching with just about any cartridge outputting from 1 to 10 mV and requiring 47K loading. The front-end mc section is a set of high quality SUTs, which have the following gains and impedences presented to the cartridge (together with some cartridge examples I used with it).:

    30x - 52 Ohms (for cartridges with very low outputs and coil resistance, such as 2 Ohm SPUs)
    24x - 82 Ohms (Koetsu, Transfigurations)
    18x - 145 Ohms (Miyajima, Etsuro)
    10x - 470 Ohms (Van den Hul, Denon 103R).

    Basically, the phonostage is a different design to all TdP's other ones, in that it uses custom-made precision inductors in the equalisation circuit, and seems to be a variation of the LCR approach. Previously, I owned other EAR pre-amps, and can verify that the 912's phonostage is significantly different from, and a proper improvement on, the current 868, and also the previous generation 864.

    The use of transformer coupling on all inputs and outputs means it is hum-free with whatever you plug into it, it also having exceptionally low noise levels for a valve -based design. There is also a useful attenuator facility which allows matching with more sensitive power amps.

    Any other questions about this wonderful pre-amp, or to discuss delivery, etc., just PM me. If you are not a full member here, note that I am also registered on some other forums, with the same nom de guerre, so you can try contacting me there

    I have been reminded that EAR will swap the faceplate out at minimal cost for a silver one should people require that to match their system, and also swap knobs, handles etc if the new owner has particular aesthetic preferences.

    Good shout, I may do the same. This pre has everything I'd want, other than it being more than I'm prepared to spend on a bit of kit it's absolutely perfect.....

    Five grand now will seem like a bargain in ten year's time, and the new owner will have had ten years of pleasure in the meantime

    You may well be right and I just showed it my wife. As she turned and walked away I am sure I heard something like "Buy your youngest son a car instead..." I suspect a green light will not be forthcoming.
