.
recently switched over to an Adcom GTP-555 mk2 preamp ...nice features , great build quality, BUT , it felt like something in the sound was missing ..
now a little BG..I run 2 separate systems from the 2 MAINS OUT jacks on the preamp ..well 1.5,
I guess...
OUT #1 goes to the BGW amp connected to the 250Ti's and daisy chains (yes , its designed this way) to a second BGW amp that pushes the Ohm speakers...
OUT #2 goes to an old NAD receiver that runs the subs
PROBLEM WAS : The 250Ti's didnt seen to have the full range & sparkle that I know they are capable of ....I tried everything to correct this EXCEPT reading the Adcom owners manual...on every preamp that I've used that has 2 mains OUT jacks , they are identical , in desperation , I downloaded the manual and started reading ...
surprise surprise , they aren't the same ...swapped cables to the opposite way that they were and all the sound that the JBL's are famous for have returned...
from the manual:
