As I have undergone quite a few system tweaks so far this year I thought it was about time I created a new page, rather than continue to edit the original one.
The biggest difference is probably my move from 7.1 back to 5.1 which has been something I have been considering for a while now but was really prompted by a recent change to my seating position. I realised after extensive measurement tests with Room EQ Wizard that the ‘centre’ seat of the sofa which the wole system was more or less designer around, simply wasn’t the best spot for bass. As bass can cloud a massive frequency range it really makes sense to have this as the priority when setting up your system and mine is no exception.
So the bestb spot in my room is actually a couple of feet to the left of where I had been sitting and as the rear surrounds sat within a shelf directly above that spot, the new seating position meant they were both over my right shoulder and the rear surrounds started to become a distraction and that meant they had to go.
The also meant I could lose a power amp from my rack too so I can now scratch off the M&K Xeno 36s and the Rotel RMB 1565.
Having a bit more space in the rack along with a new purchase (ADA XLR8-X Balanced Converter) meant a good excuse for my first real attempt at some OCD cable tidying!
The only real downside to this new configuration is that I don’t have enough AB Cinema channels to Bi-Amp the front three but in terms of surround sound, the loss of the Xenons was never going to be a big deal. With the sofa only a foot from the back wall and with excellent diffuse surround from the M&K Columns at the sides, I was never really convinced the Xenons were worth the cost, so I am happy in some ways to go back to this simpler setup.
The new setup now incorporates a balanced connection from the ADA Suite 7.1 to the AB Cinema Amps via the ADA XLR8-X Balanced converter. Do I need this with balanced interconnects of 1.5m? Probably not but any way to help maintain a clean signal is fine by me and the XLR8 was at a price I couldn’t pass up on.
I am using 7 channels balanced, biamping the front R&R (4), the centre (1) and the subwoofer (2), the L&R surrounds being the least critical run unbalanced.
