Thanks for your advice KG, sorry it's taken so long to get back with a reply. I've been on a bit of a journey of discovery. I think the simple fact is that the output from the ATR25 was too low and the mic preamp background noise therefore became much more noticeable. Unless of course the one I got was particularly low on output, I don't know. Anyway, I borrowed a Shure SM58 and made up a short cable to go from XLR to 3.5mm stereo jack (wired in mono) and tried it out. Wow what a difference, background noise almost gone, surprisingly good recording of acoustic guitar and vocals with the mic on a tabletop stand about 2 feet away. So then I tried my AKG C1000S condenser mic with 9V battery, however far too quiet, almost inaudible. So after a bit more pondering and internet trawling (I had a look at variuos mic preamps (from home made to expensive) and some mixers and some hard disc recorders) I ended up taking back the ATR25 to the marvelous Digital Village in Southampton, UK and getting a brilliant little Tapco Mix 60 mixer fo a mere £46. What a great piece of equipment, the sound quality is excellent and means I can get top quality recording on the NHF800 through line in. I can even attach an effects unit through the aux out/in loop to add some reverb if required. If you are trying to get a good quality recording of live music or speech and don't mind a small amount of external equpment, this is a good solution. Here's a picture [attachmentid=2079]. Obviously not for covert recorording but excellent for capturing rehearsals etc. I would go so far as to say that I see no particular reason why you couldn't end up with a semi pro demo with this equipment. And that's what I intend to do!!!
