Grotrian lost it's singing tone

I deal with 3 Grotrian 220's which all have very very similiar 
qualities. These are not your most powerfull instruments IMO, and I find 
tendancies amoung many technicians to voice them very hard to try and 
get some punch out of them.  (This is the one of the kinds of voicing 
mistake Del was on about a bit back.)  I think you will find that if you 
voice down for a nice round full tone you will find a pleasant tone that 
carries well, and probably wont loose nearly the power you might imagine. 

After many many talks with my voicing << Professor >> and good freind 
Andre' I find very much sense in those words Del passed by us a few 
weeks back.... something like "most of what is done to increase power 
simply distorts the tone".  This is really true.  Power is often 
seemingly confused with "loudness"... which far too easily seems to get 
hung up in an over accenting of the high partials that comes from too 
hard (for not to say harsh) a voice.  Power on the other hand reaches 
its maximum independant of that. All the added harshness in the world 
wont increase the instruments power.  Thats found in a hammer made 
(voiced) to optimal resiliency and from the pianos sound producing 
efficiency itself.

I'll defer to Andre' for the best explanation of his voicing 
proceedures... but shortly said... a nice deep needled cushion down the 
shoulders that you can feel give and spring back when pinched is the 
basis... and the rest is medium to shallow voiceing up towards the 
crown.... closer to the crown then I think very many of us let ourselves 
want to go.  Let the sound mellow out...get up there close until it 
does.  And if you  are voicing very much down, take it two or three 
sessions at a time to avoid over doing it.  If you do things right then 
when you are done the voice becomes full and round and that initial 
attack <<bang>> with no sustain disappears and is replaced by a gentle 
initial swell and long decay..... and standing back in the hall... you 
find the sound will carry as well... perhaps in some instances even a 
bit better then before.

 All this said... ... thats a very interesting observation you offered 
about that new staple attached to the wire... I knew it was supposed to 
help clean up the sound... but increasing power... ???  some how 
increaseing the effeciency of they system ??... I'd like to hear more on 
this possibility.
