Upgrade your hi fi! And your central heating!

Thank Worcester for that

i got that one in first

Bish, bash, Bosch - hum sorted!

Though in my ongoing experience the Worcester Bosch post sales support is not a patch on Naim's. Multiple requests for information to their technical department elicit the automated "we will respond within 2 days" which they didn't. Only when I went through Customer Support did technical eventually contact me, provided some of the information required by my plumber and have since once more failed to respond. Not impressed. Maybe they should spend less money on television adverts telling us how dependable they are and actually invest some effort in being dependable.

Unfortunately everything I've heard about Worcester is negative,  but theirs always the exception to the rule

I did a fair bit of research into this, and my conclusion was they're all a bit crap. The actual technology of boilers and tanks is pretty simple, and a huge amount depends on how well it's installed - that really is more important than the hardware. You know how a well set-up RP6 will sound better than a badly set-up LP12? Same thing. The local guys who everyone rates highly fit Worcester Bosch, so that's what we got. Also, Which? magazine rate WB super-highly across the board, fwiw. 

I had thought it was seven grand I couldn't then spend on hifi and music, so was pleasantly surprised when it made a difference to the sound as well our showers!

Sheer example of coincidence:

Based on this topic, I switched the Central Heating completely off. My Amps hum remained unchanged.

Then I switched the Central Heating on again.

The morning after, the house did not get warm.

So, I thought that I broke something.

Water pressure was too low.

Now that's sorted.

But I've also noticed that the Central Heating, as well as the central switch box, as well as some leads vibrate at exactly the same frequency.

This problem is not sorted yet.

I thought this thread was going to be about water-cooled class A amps!

I recall Musical Fidelity's SA470 from the late 1980s, which if memory serves consumed over 1kW continuously when on, running very hot to the touch - all 100kgs of it! I always thought it was a prime candidate for water cooling - which with a suitable heat exchanger could provide domestic hot water or space heating to other rooms.

Yes I found the same situation recently. New boiler, tank and control system/timer = less noise on the mains at the time it fires up and more importantly less noise within the radiators, which always before had a low baseline hum emitted that was audible in my small lounge and listening room when the heating was on. (+ the kettling of the pipes that was probably heard from several miles away has gone)

If you sit down in silence and listen, a house has all sorts of noises going on. I remember one place I rented my listening sessions were often interrupted by loud footsteps going up the stairs, on seeing if anyone was with me I found I was alone...spooky.
