JADIS DEFY7, can not get it to sing

Hi
I hope some of you old pros can help answer my,,well lets say help me figure out how to get my Jadis defy 7 to sing. I purchased the amp used (like new, as the seller had a  Jadis JA200 mono blocks laready and the Defy sat quiet, So I bought it in 2008. Months later i purchased a  MINGDA tube pre amp, sounded AWEFUL, Not even close to my jadis Orch reference, KT90's EI tubes, that intergrtaed was really all I needed, i made a  huge costly mistake selling and buying the  DEFY 7, I do believe that w/o a  powerful pre, to DRIVE the FQ's into the Defy, the Defy will not respo9nd. 
The sound is flat, lifeless, no dynamics, The Orch Refer had HUGE sound stage, bass, GORGEOUS life like mids, nice sweet highs. 
I wanted more and bought the Defy,. 
I just had the Defy cked in Baton Rouge, had the KT90's brand new EH tuibes biased . 
I have a  ONKYO preamp arriving next week and am about to buy a  Mitshibushi Pre amp, 
I have a  LITE LS9 , chinese tube preamp, and that pre sounds like the,,no worse than the heftier Ming Da. 
This Lite LS9 is suppose to be a copy of the Jadis 200 pre, It weighs only 7 lbs, the trans is light weight.
I get  the idea the jadis Defy needs a  great hefty powerful prem, which is what folks told me back when i bought it, I did not believe them. 

I am low on  cash and will list the Defy for $3500 and i will pay shipping. 
I will then wait fora  great used Jadis intergrated, say a  DA50.

But I 1st want to try the 2 solid state pres to see if i can get the Defy to wake up.
It I can get some better respose , i may keep it and look for a  good used Audio reserach or a  macnintosh.
I do not have $6K for a jadis pre used. 
My budget is $1K
any help is greatly appreacitaed.
I have the uncredibly  SEAS Thor MTM speakser along with the CAYIN tube cd player with upgraded opamps .
As I say I am very close to selling the hge, hardly used (Like New) amp, due to my doubts that I can get the amp to respond like its tiny brother , The Orch Reference. 
btw I am the one who coined the tag *shootout* wayyyy back in 2000, or 2001 
I stared a  thread of speaker shootouts,,,and based on that long thread, i bought the SEAS THor kits. 
I now see *shoot out* is now the common tag for speaker and stereo components comparison.
My old login was Bartokfan.
Look forward to any suggestions in my dilemma.

OK, Yes what i meant is muddy/sloppy warm mid range. 
Which I have in this cayin MT35./EL34's. Now if I roll the cheap chinese au's/ax's in the Front, has 2 au's, 1 ax,,,perhaps I will add some dynamics to the mids /highs,,But I am going to sell it.
So you are correct, tubes are warm by nature, but not according to my Jadis Orch Refer with EI KT90's, which delivered sharp percise FQ's, and , beats any SS amp. 

Tubes give life to muisc, 
There is no SS amp that can match a  good tube amp. 
I hate SS amplification. 
Not sure why folks still continue after all these decades, to purchase solid state amplification. 
Solid state is D~I~N~O~S~A~U~R

If solid state is a dinosaur,what would that make tubes? Tubes were the precursor to solid state? Me,I have tubes and solid state. I like different flavors.

@mozartfan. Do you actually believe what you post, because the more you state your absolutes, the more you show how very inexperienced you are in this hobby.

SS amps can be exceptional, just as tube amps can as well...depends on the synergy and set up expertise that you have with your system. IMHO.
Like the member above states...different flavors.

Well, True, I guess there have been great SS amps, Luxman, and others,,but the price tag has been high. 
And in the end, $ to $, Tubes high end (Jadis/Cayin vs high end SS, take your picks,,,at least for me, the more decided flavor would be w/o question, the tube amp.
Have you guys not heard/read about *The Magic of Tubes*?
Sure you have.
OK , yes here in New Orleans, we have no high end show rooms, I've not heard a top end SS amp,,nor many (Jadis Orch only great tube in my listening exp) a  top tube either.
So I can only go by what I read and what my experience of the Jadis Orch Reference.
Based just on the Orch Refer EIKT90's. there is no SS amp that will bring me what i demand in my classical  listenings. 
Sure if you A/B a  fine SS vs a  tube,,I might not be able to decipher,,,maybe I could./or not..

Lets say I am biased,,which is not a  good thing in stereo, but in my case, i am biased and stubborn.
My Cayin MT35 went out after 2 days, 10 hours,.,,I need to take it up to Baton Rouge Advanced Video, have Mark look at it,,bought it 3 weeks ago, Chinese dealer says, thats very odd, as he has sold many of these amps with no issues. maybe my Thors 4 OHMs were too much for my flipping the switch betwix ULTRA LINERA mode and TRIODE.
maybe i should have stayed with the more wattage of the 2 offerings. anyway one channel popps and hisses. 
I told him I will work with him and not to worry. 
I am fair and if my tech thinks the SEAS Thor   had something to do with this issue, I will take most of the repair cost and sell it cheap, 
paid $800, looks like i will lose my shirt on that one. = less cash for my Cayin SC6LS pre...
this hobby can really get expensive

So you have something from Cayin that developed problems in under 3 days and you're still worried about having the money for another Cayin product? As so many of us keep telling you try slowing down and reevaluating and develop a new plan. Take your time save your money and buy something really good when you can afford it. Buying once and buying right can be cheapest of all even if you spend more than you planned.
