Radiotehnika S90 A, and now what?

Hi there guys,
I continue helping a friend to built his setup, as some of you know I visited with him Audio Salon in Miami, he was exposed first time to a high end store, It was an NAD setup driving PSB towers, he liked it but!

He realized that the Russian speakers he owned in Cuba Radiotehnika S90 A, were better designed and more appealing to the sound he likes.
Well I though it was some kind of nostalgia for his experience in homeland but the guy impressed me with his knowledge cause he is a military electronic engenieer.

He sold the speakers to a friend in Cuba before he emigrated to the US a year ago, he is trying to purchase them back but the guy refused to sell them even at higher offer.

I advice him to buy as first amp this amp.

At least he has 30 days if he doesn't like the sound, amp is shipped to his place but doesn't have any speakers yet, I spent hours trying to look on the used market or new, he told me today he can push it to $1700 but I don't wan to advice him anything before getting advice from this community.

He wants a floor standing speakers 3 ways or similar, he listen mostly 70s bands, FM golden era, when the radio was the king.

I will Really appreciate your support in this project.

Link to the Russian speakers, S90 A were the model.
