Tonite I have chance to try my AK 240 SE line out pair with my RSA Intruder
Source : AK 240 use SE Line Out > Intruder line In
Dac/ Amp : RSA The Intruder
Headphone : LCD XC use Norse cable Reign Series 8 braid x 26 awg balance RSA / Kobikon plug
Cable : mini to mini diy
Music : WAV , AIFF , FLAC 24 bit and DSD
My impression :
High : very good clarity with extended crisp high , better detail than RS 71 B and Pico Power and slightly better than Duet
Mid : very clear and clean mid , a bit thiner than Duet but better clarity , Duet has more analog mid
Bass : very detail and clean Bass , not as deep impact as Duet , bass speed about the same with Duet , Duet has fuller bass
Separation : on par with Duet , I think is slightly better than Duet
Soundstage : is wider than. Duet , Duet has better Depth
Background : black Background
Hiss : Zero. Hiss lie Duet
Overall :
I have tested Duet , The Intruder , Pico Power and RS 71 B pair with AK 240
My favorite as follow : Duet > Intruder > Pico Power > RS 71 B
The Intruder sound character to mid high with better clarity than. Duet and Pico Power and RS 71 B
Duet has sound character to mid low with better mid and Bass impact
I like these two amps Duet and Intruder pair with AK 240 , for certain music genre these Amps has plus and minus point
Duet is overall better than Intruder if you hear jaxa vocal , country and blues
Intruder is better than Duet if you hear instrumental , minus the bass impact to thin and mid sound to mid high
For all rounder Duet is the best from these four pair with AK 240
Nobody is perfect , but I love these two amps
IMO
