Tube amp on top of LaScallas

Recommended Posts

Hey guys! What's the consensus on putting tube amps on top of speakers? I listen at a relatively low level. Never past 9 on a set of 22 watt monoblocks. Is it better to just get a stand for them to be on the sides ?

I normally don't like amps and other gear on top of speakers.  You can do it and may not have no real problems.  What you are after is will it change the sound or shorten tube life.  Maybe.

So essentially do it at your own risk. Good to know! Will be going a different route then. Thanks guys!

I would not do it at all, the vibrations caused by the speakers will affect the tubes for sure!!! It can help them to become microphonic and you don't want that...

looks cool but can do nothing good,  at worst you will pick up the vibrations as tubes always are a little micro-phonic and at best you will vibrate components that dont really like it.   put them somewhere else.  T

You should also be sure the amp chassis can't pick up vibrations from the sound field of the speakers themselves, or that what you sit them on isn't going to pick up vibrations from the floor (unless you are on concrete).  Of course, this is very level dependent.  It's very unlikely that vibration will make a non-microphonic tube microphonic, however.

Guitar and bass amps are usually sitting on top of the speakers, which play much louder than home speakers. Microphonics would be a bigger problem in this application than with home hifi systems. Maybe the musicians swap tubes frequently?

I've had tubes in some stage performance amps for over a decade, no problems.  A few have seen regular 2.5 hour gigs at fairly high volume.  

 

If you hear the effect of the amp sitting on the speaker, then there's a definite problem.  Compare, it may require that.  

 

EL84 filaments are particularly bad for 'singing' audibly with vibration, many an instrument combo amp with EL84's have 'extra sonics'.

I've heard all that rubber stuff leaves marks on the veneer if it's left there for too long. I bought a second Sanus AV stand to go along with my first. Thinking of putting an amp on each next to the speaker and have my RC64 in between them.

 

Room has to play double duty till I move into a house as a "ht" and stereo system.

That is a valid concern about the veneer!  

I'd put my equipment on a side wall and away from the speaker if I could.  I get a better sound stage without any equipment in the middle.  Can't always do that however.

I don't think Klipsch speakers, particular Heritage, can claim being vintage without the obligatory water stain(s). One sure way to assure authenticity!
