Wilson Audio Sasha Mk I

Hello everyone - I wanted to get some advise on buying a second hand pair of Wilson Audio Sasha MK I speakers, and pairing it with a Plinuis Hiato amplifier:

which I have connected to a Plinius Koru phono stage:

Connected to my Clear Audio Concept turntable with the factory installed MC cartridge:

I listen to all types of genre, from rock, pop, jazz, hiphop, and I also have a REL T9/i sub connected to the system, which I may or may not use:

Could I please get some educated/professional advise on whether the Wilson Speakers would be a good long term investment for this setup.

Thank you in advance
 So, back to the OP's question. My answer is only your can decide what sounds good to you. If possible try to get a home audition. If not, see if it's possible to take your amp to wherever the speakers are located.

@ricred1 , I can guarantee you have a good friend as a dealer, with all your changes I love you too, you have obviously sold some very good equipment on the used market which is where I normally buy.
Wow, I didn't think the conversation would go down this path, but thank you for all your advise ;-)

Unfortunately I'm not in a position to listen to these speakers on my system, therefore I can only look at the technical specs and ensure it matches my amplification, and  also read the myriad of (mostly) positive reviews out that there.
I own a pair of Wilson Sasha 1. They are amazing speakers and excel with most genres of music; especially jazz, classical and rock. Like some have said, wilsons are not everyone's cup of tea so it would be best if you could audition it and hear it yourself.

The Sashas are extremely transparent and detailed speakers so proper setting up and equipment matching are key to making them sing! Also, do consider the large room space required to set them up properly.
