ROTEL RA-1572 Integrated Amplifier review

Rating:
✩✩✩✩✩✩✩✩✩✩

It was the best choice. I've tried several amplifiers starting with analog Yamaha and Onkyo models through NAD  C375 BEE and Hybrid Digital NAD C 388 running my Bowers & Wilkins CM8 S2 speakers. ROTEL was the best choice. I waited several weeks to get one but it was worth to wait.

From the first look at the amplifier seems to be robust and very well done. Front panel is assembled by power switch in blue LED circle (light  is adjustable), phones 3,5mm socket, USB for Apple iPhone connection, speaker zone selector, input selector, dimmable display, volume and menu setup buttons.

Rear panel is assembled by all the connectors as per specification as well as APTX Bluetoth adapter to connect your mobile devices for example.

Pros:
DAC & Number of digital inputs
Sound quality and Output power
APTX Bluetoth adapter

Cons:
Cheap looking remote controller
