I bought this phono Head amp recently and haven't used it as I'm still waiting for my 401 plinth to be finished... An absurd amount of humming and hawing re a MM stage has finally ended with me taking the plunge on a Valab LCR 1 MKII MM/MC phono stage so unfortunately this very highly rated unit is now superfluous and up for sale. Please note Angus's (Phonomac) mods, carried out about a year ago, have brought this to even higher spec than the Denon HA-1000!
This is Angus's (Phonomac) description about the improvements/mods to the head amp:
"The large green electrolytics around the front end are Nichicon Muse ES bi-polar caps, and the values of the input and stage coupling caps have been increased to HA-1000 standard or better. Denon used ordinary electrolytics for these, since good bi-polars weren’t available at the time. However ordinary electrolytics will be subjected to small reverse voltages – not good for distortion.
The green and red box capacitors are polypropylene film caps replacing mylar, and the yellow box caps are polycarbonate (ignore 100nH marking, the H is a manufacturer’s mark – it is in fact 100nF in value).
The black and gold caps in the power supply section are Panasonic FM, the best cap for power filtering/smoothing within their voltage range."
I'd like back what I paid £230 + postage
