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.

@clearthink...……………………….

First, think clearly.  The thread is about purchasing many cheap preamps, the one in question being around $500.00.  What do you think you are going to get for $500.00  from a Chinese company no one ever heard of that is trying to clone an expensive ARC preamp for a fraction of the price?    Why don't you buy one and if isn't a piece of crap, I'll buy it from you?

Second, I do not need to be schooled by you and I have nothing against Chinese goods.  My Golden Ear Triton Reference speakers and Triton One speakers are BOTH made in China (but they don't sound like crap).

"This is vile, hateful, prejudiced language, the wholesale, unconsidered association of Chinese manufactured equipment".  My post was neither vile or hateful or prejudiced, you are trying to make something that isn't there.  The preamp was a knockoff piece which is illegal everywhere except probably china.  Get off your high horse.

Stereo5, I feel your wording, and attitude, to be very offensive. That would be like me saying, I do not like the SQ of Mac amplifiers using autoformers ( which is true ), but, understand those that do like them, as yourself. I also feel all tube preamps " color " the music, as I use a passive device, but again, I understand why folks prefer them. You obviously have very little personal use of some of these so called Chinese made clones, so how can you comment. Besides, I know some folks who would not purchase your speakers, for the very reason you put down this " Leaf " product; " Made in China ". Just not justified, imo.....I apologize if I hurt your feelings in any way. Audio, and more specifically, music listening, should be fun, and positive shares, instead of blatant put downs, are needed here, on the 'Gon. Enjoy ! MrD.

What is needed is truth.  Many Chinese factories make knock offs using designs that they have illegally copied(or stolen to be more specific) and then flood the market with them.  They have often times used cheaper parts and such, and the results are undercutting the very companies that they have stolen from.
 
Cable companies are another favourite target, but of course it’s not limited to the audio world.  It’s a relief that finally the American government has told China to stop behaving this way and has initiated tariffs to back up their position.

@mrdecibel ................

I put down the Chinese preamp because it is a cheap imitation, knock off which is probably illegal, nothing more and nothing less. If you can’t see that, then you are blind. Putting a 500.00 preamp with an amp that cost more than 5K when new is just plain silly and will not yield good sound. I purchased a cheap Chinese hybrid integrated back in 2006. It was a Yaquin. After using it for 4 days, it caught fire and the manufacturer refused to warranty it. It went out in the trash, hence “cheap Chinese junk”. I am willing to bet that more than 90% of us here would not do what the OP proposes.   Regarding my system, no worries you don’t like it.  Right now I am loving the sound of my McIntosh MR88 tuner playing through my McIntosh C2500 tube preamp, into my McIntosh MC302 300wpc  amp WITH autoformers and listening through my Golden Ear Triton References. Breathtaking sound to be sure.    

Why don’t you try this: purchase the Dartzeel clone that is selling for $1200.00. It must be a real bargain as the real amp goes for something like 17K. The real Dartzeel uses 4 caps larger than soda cans. The clone uses caps smaller than my finger. I am sure it will sound just as good (not).

stereo5"I put down the Chinese preamp because it is a cheap imitation, knock off which is probably illegal, nothing more and nothing less. If you can’t see that, then you are blind."

I am not blind my vision and hearing are both exceptional and you’re frequent, repeated, incessant hate filled attacks on Chinese products reflects a deeply rooted prejudice, intolerance, and ignorance of cultures, languages, and practices different from you’re own and if this product is illegal in any way you are free to report it to the relevant authorities for proiper remedial action but of course you will not do that you would rather spread you’re distaste for things Asian hear!

Notice I do not say that those who disagree with me are stupid which is basically what stereo5 uses for reasoning, logic, and argumentation!
