Sony TA-E88B ???

HI to everybody,
I just bought a Sony TA-E88b and may need some advice on it.first i will give you my setup :
computer-amarra-Focusrite Professionnal converter - Sony TA-E88B-----mcintosh 2255----JBL L300
ok. i have at my disposal a C11 original Mcintosh completely check and running well
a Luxman C1000 and the Sony TA-E88B.Some people say that the sony is great .I bought mine ...all the important caps has been changed and the pot cleaned.
Can you give me your experience about the "sound"...
I am VERY disapointed . Very. Out of the 3 ...it is by far ... I MEAN far the last musical of the 3.
it has no "life". the sound is a bit 2D instead of 3D.The "music" that goes out is "flat"
It is FOR SURE quiter than the C11....but NO MUSIC COMES OUT.
