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.

@ Stereo5, Yes, Exactly,,I thought things through very carefully,,I recall from yrs back ~~SILVER~~~ was a  hit among audiophiles,,,I had cheaop pure silver flat,,,i thought it was a joke,,,only 5 tiny strands laying flat in plastic,,,but a  light bulb went off in my head,,silver,,i wonder what kind of conductivity propertiers/charateristics it has,,,~EXCELLENT~~~ 8%+ more than copper = more ZING~~ to the higher/mid FQ.s OK, what can I do to bring as much silver into my system as possible within budget constraints.. 
OK lets see  what is offered in pure silver  interconnects~~YEs I like these nice flat, super extra wide, about 10+ strands all bunched at the connect,,~~Sweeet~~, now for speaker wisres,,,~~hummm, that tookmsome time, but after due diligent research,,Found exactly waht i was looking for @$100/20 ft piece, will make 4 sections, 2 @ 6ft and 2@ 4 feet, as my Defy sits closer to one vs the other Thor.
OK what gague,,,hummm 12 too pricey for my budget,,,ok, lets see what  a 14ga solid silver,,oh btw it is STERLING SILVER,,not pure,,sterling = 85% silver,,good enough for me.. 14 ga arrived,,,sweet, nice N thick for speakers fq's. ,,the lower mikd bass could use copper, as there is no zing in the lower FQ.s,,but heck, for $100, ordered a 2nd 20 ft piece.
Now for interconnect plugs,,hummm, Defy looks like all the rest, ,,+ the new spades i ordered at $8 for 4,,look like all the rest,,even your $20K speaker cables /$10L interconnects you see on the market have these 2 cent connects, = mostly brass. So what is the component on these connects behind all/every stereo, including jadis 500 mono blocks at $50K+++, its brass, what is brass, brass is like 65% copper, and the rest is zinc and other crap. 
So all the ones I am using, the cd connect only, this one has to go 100% pure copper,,waiting ona  a  chinese seller to tell me what ~~4 pieces means = 2 pairs???~~4 pi8eces at $35,,,waiting fora answer,,,will trash the cheap Defy 2 cent plug for pure copper,,,now the Cayin CD player and the Defy will have the tiny cheap 2 cent wires that run from the board to the plug, each nearly 1 human hair thickness, those will be trashed,,i bought  .1 MM and .15MM pure 100% silver wire, 1 ft each at $35/ea ( or near that price can't recall at the moment,,,tech can decide which he wants to use...The speaker wires will have no connect,,it will be direct connect. 
It is the half round style 14ga i purchased.,.
Lets see what lse did i figure out as upgrades,,,I recall a  guy in baton Rouge telling me lets swap the cayin's opamsp to new higher quality,,we did and did get more bang for the buck,,well lets see whats new in opamps,,its been almost 15 yrs since,,,hummm, what are these ~~Discrete opamps~~ really cool looking,,,lets see,,humm, ok these look interesting,,and the lab has a vid on YT,,yes I like this lab,,and the clincher is, its made in USAQ Colorado,,,has 6 single new super highb tech ~Discrete~ opamps arriving,,what else,,,all the cheap 2 cent caps in the cayin have to go,,, four caps @ 0.1 uF, eight caps @ .022 uF, and 2 @ .33 uF's,,all will be the more affordable silver/gold oil supreme/white body,,the black are about 25% more = out my budget,,and will you really note the extra gold in the cap,,,,maybe yes, maybe snakeoil. . I do have budget restraints.. an\yway,,what else,,,I took my collection of amperex (many BB's, my favorite) ax's, au/s, 6dj8's and shipped them to a  guy in washington, he will sell them for mea nd send me some change,,,so in the meantime, whats new on the market,,,hummm, I like these Shugaung and PSVANE, have some ax/Shu and 2 PSvane au's comming from  HK ,,but i recall I wanted the au's in the Defy to be the tall bottle SQ Philips/NOS,,,oh well I'll roll the 2. 
+ found out last night a  lab called TAD has some really nice looking 6922, /AX 7's,,I'll order the 4 AX;'s for the Defy and later on when i have cash, will  order 4 TAD 6922 for the Cayin 17. 
....The cheap china clone of the Jadis pre will stay as is,,later on I will get the new cayin mark 2 tube pre SC6,,,on that unit i will trash all the cheap caps and replace with M silver oil supreme, or something along that line- depends on size of caps,,smaller caps, = more cash for superior M's....and yes  the Defy late next yr will go back to baton Rouge and have some caps replaced with M's,,,not sure how many, or what line of M;s, small caps are affordable for silver /gold. Here is a pic of the Defy...loks like alot of caps,,not sure which M im  will go with,,that mod could costa  small fortune.
 oh also the Thors will have new xover, with each getting 1 10uF Gold Silver Supreme I bought at a  bargain price off ebay,,and the rest of the caps, M silver Oil,,the cap for the lower midbass a  cheaper M cap, all new Mundorf resistors, new copper coils, 
Here is a pic of the Defy 7 under the hood, luckily the layout is claen and open as the Mundorf silver/gold line are quite large.

@ davey,,can you prove the jadis 500 monos have pure copper posts? or how about the mac, ARC, Cary,,do they employ pure copper posts/connects in their designs? 
Its a industry standard to use brass. Sure the mod may only gaina  1% pop in sound,,but perahps more,,more zing, higher, smoother  connectivity transition/flow of electrons. For $20 a pair , and only changing the posts you use,,it might be worth it 100% copper vs 65% copper. 
+ the thin wire on the cayin from board to post,,who knows what it is made of,,i suspect all amps use this tiny whoknowwhat quality wire...
I  will mod to 100% pure silver,,and a  thicker grade.  If you can show Jadis uses high quality pure silver from board to post,,I'll hold on that mod..When my tech emoves that wire from the 8 post jacks,,I will find out how thick and what  is the elements  of the wire,,,,,My guess it is copper,,, but who knows....For small change its worth it to change those speaker post wires to pure silver. 
Remember its in the upper mids/high fq,'s is where we are all after ~~zing N sparkles~~The swifter the current flow, more shimmerings, sparkles, clarity. 
Oh also on the speaker wire,,there is a idea thata  solid wire conducts superior to tiny strand wire. 
I will have a  14ga 85% silver solid strand...I think that will makea  nice mod in delivering fq's with more authority. 
All those mods will most likely spoil the voiceing of the Jadis.  It will be unsaleable after the mods.  Too much silver is never good.

The OP just seems to be on a quest that is his own...with little thought to any of these factors. I am off this thread...total waste of time.
