Wharfedale Jade 3 aluminium tweeter problem

No not really, I have aluminum inverted tweeters on my Focal Electras and the tweeter was mercilessly and revealed everything in the system. I got some tube power amps and Holy Moly these tweeters found the right amplification and I don't mean rolled syrupy slow sound you remember from your grand parent's RCA console. No they quick crystalline and create a huge soundstage. Imaging that you can easily call holographic.
When I had friends over to listem I wouldn't say much about these relatively inexpensive tube monoblocs. Every comment that my speakers sounded a lot better, what did I do to get them to sound better. You know the punchline.
As for your tweeters they do break in hard or not it is suspended and has electronic elements and magnet in them. You are right they don't get burned in as fast as the other elements. Only time and listening will let you know if all the drivers in your speakers are maturing into a cohesive unit where they mesh well. The tweeter is a part of it but not the only one.. That said if you keeping your equipment as it is today you may be ready for a nice silk or whateve fabric tweeter. Do you any audio buddies around, if you do you can ry your aluminum tweeter with various amplification.
If you just can't stand them return them and get a fabric or paper tweeters. The time and discomfort with metal may not be worth it to you and I don't blame you. In another life I hade two systems The one with the Focals and many amps and sources, but wasn't until I found the right amps with the help of Trelja on these forums after 6+ years of trial and error (mostly error) I found nirvana.
The 2nd living room system is and was easy to listen to. Von Scheickert VR 2s powered by a smallish el-34 integrated. I had a MMF-5 turntable there and a couple of tuners one an old Sherwood and a Sansui the first cd player was a Music Hall MM CD-25 player.
I wish you luck be forewarned this hobby is addictive in some people.

Mechans: Thanks for your detailed explanation. I'm a poor music lover, always looking for budget gears, indeed I already found my audio nirvana with JDS Labs ODAC > Class D Audio 400C power amp > Wharfedale Denton 80th Anniversary speakers, this combination is musical enough to bring tears and joys when I'm listening, just that I'm trying to seek some dynamic improvements, though I'm not used to giant size of floor stander speakers due to immobility of moving those. I got an refurbished NAD 3020i, though I was trying to use it as preamp, it does not sound clear enough to me, and I found that I dun like to put preamp + poweramp as 2 blocks of big gears, in the end still prefer without preamp, control volume from computer DAC volume, this sound best to me.

I think the Stereophile measurements reveal a titled-up treble with the Jade 3 that could be a problem for those sensitive to that range. You might take a look at the review to see if it's simply a characteristic of that speaker that will require different partnering gear (or a different speaker).

Good luck,
Scott

@Scott: yea, before purchase I did think about the high, as reviews also pointed out that. If that's the case, this is totally unacceptable to me, cannot defined as Hi-Fi sound in any sense at all. I discuss with the distributor to see what I can get further explanation or understanding...thanks for your opinion

I would not change your system to accommodate the speaker's inherent problems. If you go on a wild goose chase looking for different electronics, you could spend more money, and get few positive results.

If you can, I would return the speakers to the dealer and get a refund, and start over again looking for a similar sounding speaker that has more dynamic capability.
