Finally I have found the perfect partner for the LRS+: the Copland CSA70 integrated amplifier.
Spec wise it kind of defies logic, comparing to what most people (and myself) thought that was needed to feed the little Maggies, but it is a revelation!
This amp totally transformed the LRS+ and solved all treble issues. True, I still have the 10w 1,5 ohm resistor in place (too lazy to remove it?) but the sound is beautifully balanced, free from any sibilance or aggressiveness.
Absolutely every aspect of the sound gave a gigantic step forward in quality, especially the soundstage, the sense of transparency and bass delivery. No subwoofer needed in my 18 sq meter room. The LRS+ are indeed a miracle!
This is the entry level from the danish brand and can deliver 140w / 4 ohm, but most importantly it is designed to handle loads up to 1 ohm! Brilliant stuff.
I only wonder what the CSA150 could bring to the table… but I happy with the CSA70 and my bank account too, so case closed :)
