The Sansui alpha will drive well most speakers i guess , it is a synergy question ...
Myself i will buy a Tannoy dual concentric if i would need speakers... They are mythical product too and i owned a pair for 45 years ... 😊
be very careful to order one out of the Us or Canada ... Scammer know that these products are in demand ...
My actual system for the price is so good , low cost yes, but not low-fi at all ... I pity those who own costlier system...I am not far behind them as much as they think ...😁
What matter in audio is synergy first, buying the right components for sure but the price tag dont tell the story here about the acoustic final experience and satisfaction ...Acoustics knowledge rule after synergy and the way we learn how to embed mechanically, electrically and acoustically the system matter more than ANY UPGRADE ... Those who brag about price tag dont impress me now at all ... I learned a lot by experiments for few years because i am retired ... I know what is timbre, crosstalk, and spatial acoustic factors for example by learning how to control them at will in my room ... Buying and plugging costly component is not the hobby, learning acoustic or electronic design is...I learn acoustic but i dont design speakers nor amplifiers , i only learn how to put them rightfully in a room ..
My best to you ...
@mahgister many thanks. There’s an alpha 907 for sale on USAudiomart! What period speakers would pair well with this amp?
