Only experience i have is that i fitted some new valves in my phono stage last weekend. TBH they sounded great out of the box and have changed very little since.

Why is the big DK not sounding how you'd like?

Remember any new amplifier will need a few hours to get singing.

duh! everything in hifi has a burn in time!

even the support platforms that PB uses have a specified 'molecular stress settlement' time!

I'm not sure about magic pebbles though

Depends on the tube, small signal tubes take longer than power output tubes. I would also say that tubes like the 6X4/EZ90/U78/U707 take years to relly sound their best and have a life expectancy of many decades. So forthose withMinimax Pre's and Phono-Pre's you ain't heard them at there best yet:shock: I also feel that this is what Cryogenically treated tubes bring to the mix, the sound of a mature tube, but without the ageing downside

pre amplifier valves last for ages and can take ages to burn in

the up dated valves I bought sounded good out the box and better after 50 hours

now sounding very good

Tubes definitely have a burn in in time from new. Takes a while for the cathode to stabilise. Usually this takes about 100 hrs or so...

Cheers,

For how long should I run in the granite blocks that my speakers stand on? Should I burn-in my new silver-plated power plugs by using them on the fridge for a couple of weeks before putting them in the system? How about my TT mat?

Hell, this is all so complicated.I've just realised the room was newly carpetedbefore I put the system in. Now I've got to take it all out so I can properly run-in the floor covering.

Granite is tricky - as you can imagine, the molecules move very slowly. Best performance is reached about 500 years after the plinths are cut.

I use a couple of headstones from the local Micmac Indian burial ground. Great sound, but my CDs have started flying round the room on their own....
