I have two amps from RSA , rs 71 B and latest My Intruder
The Sound Quality from The Two amp are not similar , both are very good amp .
The best from rsa amp , There are very quiet .
My impression between RS 71 B and Intruder
High : Intruder more open and has extended High than My RS 71 B
Mid : these Two amp have the character mid from rsa analog and Neutral sounding mid .
The Intruder has Better clarity In mid
Bass : The Intruder has Better bass detail,, more punah and very Deep Low bass.
Especially In High Gain .you can drive High impendance cans without any problem.
Separation : The Intruder has slightly Better separation. That i can feel The placement from The
Instrument more detail and accurate placement .
Soundstage : The Intruder has wider and deeper Depth compare to RS 71 B.
Conclusion : with intruder I can use my fit ear 334 and UM miracle in low gain
Um miracle I use balance cable .
I have jh 16 pro sound also very good with my intruder
You can hear more balance than from rs 71 b
Intruder is not overkill for iem , because intruder has 3 gain setting
I use for iem In low gain setting .
With the high gain you can drive your high impedance cans like HD 800 , T 1
No problem , intruder in high gain is better than My rs 71 b.
Note : the dac section IMO is as bonus from Ray , if your source Mac or pc is very good quality
16 bit / 48 kHz USB dac .
I play all my music in WAV file , the best file music to date .
This is my personal impression
