    The GCPH I tested did hum and had a shed load of additional problems. SUT's can be very microphonic too. I know I'm biased but the A.N.T. phono stage deserved the 5 star award it got. I can offer a sale or return if anyone is interested.

    Yes, there is very low level hum but I think the Underwood mods have lessened it compared with stock. I must say that sound quality is superb, better than my old EAR 834P and that was no slouch. What kind of problems did you measure in the stock item?

    By the way, I thought long and hard about the A.N.T. but I couldn't easily hear one so went with my gut instinct that the GCPH would suit.

    Well, I'm using a loaned AT630 SUT which can't be any good 'cos it doesn't have foo wiring and nor does it have an expensive box and it "only" sold for £45 at the time. It inverts the phase it seems and this is audible, but it doesn't hum at all and the audible bass range is very good indeed. Of course, it could be said that my system doesn't have the definition of a "proper" system, but it makes good music so I'm happy...

    I think Linn did a very fair active MC stage on their LK1 and Kairn preamps, limited mainly by the line stage the signal passed through IMO. Minus 80db s/n is pretty darned good for a domestic ss MC stage IMO and around 15 - 20db better than the equivalent Naim ones at the time I think.

    I wonder how good or bad the OCC versions of the Sowter transformers are?

    In any system, there should be no hum at all. Not even a trace of hum should ever be heard under any circumstances!

    The A.N.T. and Whest PSR.30 achieve this, as does my own AT630 that cost me under £30!!

    Regards

    I missed on at the weekend which went for £37 IIRC. With the phasing right I think it's ok.

    I dare not ask really, but does it compare at all with modern expensive SUT's (assuming that today the 630 would be around £150 and the 650 around £200 I suspect).

    It does.

    MC transformers needn't cost silly money. Look at what is actually required and what that costs to produce.

    The Sowters go for about £100 each. You can put them in a bling box if you like and charge £2000 - I won't tell

    I suppose the cheap price puts audio foools off.
    About $100.00 a pair and with a valve phono stage they are amazing value.
