    So what sort of amp continuous power output is best? The floorstanders have a maximum power input of 400W.

    I wouldn't take any notice of 'power input', save for that it will handle what you throw at it, with all the usual caveats.

    The question you should ask yourself is: what sound levels do I want/need? The answer is related to the sensitivity. I listen to music at an average level of 80dB, 90dB peak, at about 2 metres. My floorstanders have a sensitivity of 90dB/8 Ohm watt/m, so for the peaks I need only 1 watt! but at 1 metre. At two metres, that's 4 times the needed power (inverse square law) that is x2 =3dB, so 4x is 6dB, I will need just 4 watts, per 'speaker. Other things, like space into which the 'speakers are to operate, sound absorption of the furnishings etc. mean that this is an estimate, but shows how little one really needs. Of course, as sensitivity goes down, power requirements go up, as it does when impedance goes down. So 4 Ohm 'speakers, at 3m and 85dB sensitivity, in a large, well furnished room will need a lot more than 4 watts!

    I have found a sound level metre very helpful in these circumstances, and quite an eye opener (if not brain opener as well!)
    cheers.....Bryan

    Bought a Knosti record cleaner. It's ok (it's cheap) but having cleaned just two records, the annoying thing is the spindle that goes through the centre hole. When I'm trying to unscrew the clamp after the record has been cleaned, there is nothing to grip and the spindle starts to come out of the other side clamp, which then makes the clamp you have to remove, difficult to remove. I'm going to glue the spindle in place into the one half of the clamp. I can't see that being a bad idea as I can't see why you would have to remove the spindle at any time. Unless anyone knows different.

    I have one of those,if you hold the record horizontal with the bit of the clamp that has the spindle at the bottom you can put your finges in the dimples and loosen the two parts pretty easily
    ps the spindle should be attached to one half of the clamp already!(well mine is and has always been)

    Yes, there is a sign of a bit of dried glue on the spindle, the part that enters the clamp. Obviously it had come away. All sorted now with two small blobs of superglue. Unscrewing the clamp is easy, it was lifting it off the spindle due to little to grip onto. I suppose I'll get used to the procedure.

    What prompted this buy was I bought a second hand LP that must be the dirtiest record I've ever bought. From the seller's POV it looks fine - no marks or scratches. I was cleaning manually using a bought solution with a micro fibre cloth, plus wiping with a carbon fibre and velvet brush with the record spinning at 78 rpm. The stylus kept collecting a lot of gunge every time the record was played. After one clean with the knosti, the surface noise has reduced greatly but the stylus was still picking up some gunge. It has been the same with a WYWH half speed mastered that I've been wanting to clean better since buying it years ago. It looks as if the first clean dissolves dirt but doesn't fully remove it. Do you clean records twice Steve? Obviously the stylus picking up dirt is also cleaning out the grooves.

    no just the once but for a good few rotations in both directions,think last ones I cleaned I used pure isopropyl alcohol as had run out of the fluid supplied,never had issue you describe but the albums I have cleaned have been old ones of mine I have had ages not 2nd hand,so mine may have been relatively clean to start with in comparison to ones you cleaned?

    Yes, possibly. My old records shouldn't need cleaning - they've been stored correctly. This Knosti will be useful when I buy s/h - should have bought something years ago.

    I have an okki nokki I've had for years. IIRC the solution is 9 parts de-ionised water to 1 part isopropyl alcohol and a teaspoon of wetting agent. I use Ilford ilfotol for photography but works very well. Usually one clean is enough and I don't get any gunge on the stylus afterwards.

    My advice regarding the cleaning solution is free and impartial . Ilford ilfotol works well as a wetting agent or you can use a drop of washing up liquid

    I've got a Knosti, but have read the cleaning fluid is not very good although I don't seem to have had a problem. Nothing wrong with a drop of washing up liquid as a wetting agent. Going off the subject of record cleaning washing up liquid makes a good household cleaner, often better than these specialised cleaners for bathrooms, kitchens ect.

    So is bicarb of soda - great for cleaning baths and sinks. Shall we rename this thread, 'What I use for cleaning the home?'
