The Rotel RB-1590 This amp in particularly exceptional reproducing bass, midrange and treble without any coloration to everything I've listened to.
In this video there are far from the shortcomings presented, therefore sorry if there are data deficiencies or errors.

Good video , but there is a slight mistake , the RC.1590 has 8 x 10,000 mfd total giving 40,000 mfd per side , not 176,000 mfd.

@enduro500sp

Thank you for the information! For the money i have a hard time finding any real competitor to the Rotel Rb1590.

@dmcanal6016

Amazing❤

@AudioElectronicsChicago

good

@jowblow2171

The Rotel is a Beast of an amp but the Accuphase is just on another level. Corvette vs Lamborghini.

@mahasidha9

I would love for you to do a review of the new Michi X5 Series 2

@bryansu

can u do a review on other china amplifier brand like denafrips apollo

@jmusicca7779

can someone tell me what you honestly get out of these monster amp models? like i can tell a difference between cheap and not so cheap, vintage under and new over-advertized output numbers and sound signatures... but honestly - what types of speakers you must be running at home to ever need one of these and what sound difference it makes? or is it all mostly bragging rites

@ElderPinto254

oeh two monsters thats not easy ... the looks is easy that goes to the accuphase .... but the price is there to for the accuphase...

@ganck1147

Paper specs does not tell you how an amp is going to sound. Some yrs back i bought a used accuphase just to see what the fuss was all about. However, after only 2 songs, i took it out of my setup & sold it. I don’t like its sound character. I find it a bit unnatural. Anyway, this is purely just my opinion. One of my friend loves Accuphase & have been using it for more than 30 yrs.
