    Yep, the mains transformer still runs rather hot. It must reach over 40 degrees C. I've ordered an infrared thermometer so I can make some proper readings. I do however seem to have cured the mechanical buzzing the transformer made by mounting it on silicon bushes. I think I'll try attaching some heatsinks to it but it'll be a but tricky as the sides aren't flat.

    Other than the hot transformer, the only negative thing I've been able to think of with the amp is that the power LED is too bright. I was just going to add an extra resistor but I think I might connect a pot in series instead and mount this where the volume pot went. I need to mount something there anyway to fill the hole so I may as well give it a purpose.

    I had my first experience of valves last night.My friend has very kindly loaned me a Art Audio pre/power combo.Had a really good listen to it last night and was very impressed.I am a tad obsessive about sibilance and have pointed the finger at everything apart from my naim5i amp.The valve combo was much more forgiving.Female vocals are fantastic,symbals sound lovely.I was suprised at the lovely bass.I listen to a lot of rock and found the combo lacked some of the attack of the naim but overall a far less fatiguing sound.Iam quite interested to hear what a combination of valves and ss would sound like.

    I'll bring my Croft and Copper amp with me, Tony, next time I'm coming up to Glasgow, and you'll be able to hear both combinations

    No worries, dude. It'll be next time I'm up visiting Snapper, whom I think you should also meet, as (like me) he was born just around the corner from you

    ANYTHING compared to mid-period Naim is going to sound more laid back and refined IMO...

    I repeat, Glenn Croft's new integrated (£1K inc phono stage) will sound just what you'd need - the atmosphere and 3-D of good valves, with some control and power from solid-state. A highly addictive combination IMO... and the new control knobs make it look far more expensive than it actually is IMO.
    I can't go on and I can't go back, I don't feel so matter of fact,
    I tried and tried to make good sense, What's the good to try it all again?

    Yep, the new Croft integrated is a fine sounding amp. And agree the new knobs look much nicer. You just know the money is being spent where it matters - pretty much like a Caterham 7 - everything is about performance and not much frippery. Just be aware there is no remote control, which might be important for you.
