The speaker/amplification wars continue

SET amplification vs PP amplification
High sens speakers vs ~`The INEFFICIENTS~~~
You might think this topic belongs over on amps room. Not at all. 
SET + High sens (91db-120db)
PP + Low sens = The Inefficients (below 91db)
Sunday I hope to get Richard Gray's 211 SET amp he builds in his shop.
This will be my 1st ever exp with SET amps, Not once have I heard a SET amp.
I know now what a  PP can do. 
I have various FR 91ish db speakers for testing.
Thinking it all over.
My only concern is classical music, Specifically full orchestra rocking N rolling. 
While listening to my Defy 7 6550, the orchestra is not separated, its all blended, like a  Louisiana Gumbo.
I'm guessing RG's 211 will bring  in details which a  PP amp just can't manage. 
I am not sure ,. just guessing here. Now all the YT vids on SET amps, have easy jazz, solo instruments, nothing complex whatsoever,. 
So obviously I will not test with my usual reference cds, Gatemouth Brown Gateswings, nor Sophie Milman. ,,well no actually we will start with Gatemouth, as his cd is high chaged with  thick stuff going on, Lets see ifa  211 can handle its business.
Next I will test the 211 witha  bunch of high quality classical, Rip Roaring full orchestra. 
Will tghe 211 pass with colors and separation and SLAM! or will the big bad boy go down in flames , all discobobulated and coughing its guts out.
Will post results. 
If SET wins, Defy is up on the auction block, actually ~buy now,/ships free~Going to takea hit on that one, as i have $1500 in upgrades, amp is from the early 2000'ish? . , amp hardly used, . Maybe 3-4 yrs

Yes The one and only
Richard the electrical genius.
He;'s been harping on me, **You have the wrong speakers** with my Seas 87db + DEfy 7. 
He was right all along, Had I listened I could have prevented going down the expensive Thor upgrade road.
Now I am going FR/high sedsn, now he's harping , **you have the wrong amplification***
He may be correct, not sure til i catually get his 211 amp he designed. 
I think he  sells this amp, didn't say  specifically, all he said is *folks who use MY 211 and 250,,,,** So I am guessing I can sell my Defy and get his 211. 
Sunday he'll be at his shop, i'll get the amp, and will know whats up with the SET sound.

WEll it does have tons of reserve power.
And Ricahrd is willing to install some higher quality pots for very easy biasing and far more flexibility, = the ones Jadis installed just a pinch one way or the other. I think for $300 he’ll install all 4.
So that issue can easily be resolved.
Yes 12 tubes X $40-$50.
$500 for 2k hours. I plan to go 2500-3k.
What the defy does possess are the massive blue Philips caps, which are worth their weight in pure Gold. Those caps, 2 on top, 4 underneath are musically magical.
+ I upgrade the 12 caps under chassis to Mundorf SESGO, really super nice in bass/upper bass.
No snakeoil, I heard the upgrade , even blind test i could say which is which.
Most of the resistors have been upgraded to Takman Rey’s, Which made some gains.
All in all this is one very musical amplifier, which i am not sure i want to part with.
Its is Jadis you do realize.
The issue with lack of separation in orchestral instruments may be more to do with the FR speakers.
can’t say for sure til i hear the RG211.
Then I’ll get a good idea what the Defy is all about.Its potential.
+ I’m not so sure these Svet 6550’s are superior to EHKT88’s. RG says its the same tube.
Not sure.
I’m thinking I can get some more out the Defy with the EHKT88’s.
+ These Svet 6550’s are getting up there on hours, 1500-2k, so some of the upper shine is rubbing off.
All these factors have to be considered in this shootout of the Defy6550/used tubes vs the RG211. 
+ Have a  higher quality FR arriving  next week, a  4 inher, Again allowing for more testing and superior judging. 
Could take some time before we get some clear ideas whats going on  here in this shootout of SET vs PP.
RG's 211 has  high quality trans,. vs Jadis' massive trans. 
This could end up with a  
System 1 and System 2. 
Keep Defy + add the RG211.
