I use these speakers for 2 years.
The Infinity Alpha 50 have serious trs impressive they descend down almost without dynamic compression. The mdium trs is good too, only the high times may seem aggressive trslgrement high level but it can be easily rectified with an amplifier in the mild fever.
I tried other models in this price range, but for most I thought the other speakers was suffering from a significant lack of low rev low seat for most of the library .
I think the price-quality ratio is excellent, a good finish and a trs trs good sound.
At home they are associated with a HK 3470 and HD 750, there is nothing repprocher these speakers for the price we will have great difficulty finding speakers capable of great magnitude in the low and at the same time in the mdium softness and precision in the treble.
I put 9 / 10 only because I think the fever is high level lgrement aggressive.
Otherwise trs good deal,
