Weak Link ?

[Deaf Cat]

Hi,

At last, I have a SB2 - wonderfull bit of kit - small silent and remote to cd collection - FAB.

However, I am in need of some help or suggestions, I seem to have lost a slight but noticable amount of clarity/dynamics.

--System Set Up Pre SB2:
Lacie 500GB Firewire HDD with wma lossless files
Laptop with WMP9
M-Audio Audiophile USB sound card
Chord Signature Digital Cable
Arcam AVR200
Cambridge Audio Pacific Interconnect
Rega Maia3 to fronts

Quite pleased with the sound.

--System Set Up After file advice from these forums:
Lacie 500GB Firewire HDD with EAC/FLAC files
Laptop with Slimserver
rest same as above.

Quite amazed at the difference just by changing ripping style and file type, To me bass now sounded so much nicer and tight, so so much more separation and clarity...wow

--System Set Up with SB2:
Lacie 500GB Firewire HDD with EAC/FLAC files
Desktop PC
Network Cable to D-Link Wireless Router
Wireless SB2 (volume fixed on max & no limit cbr)
Chord Signature Digital Cable
Arcam AVR200
Cambridge Audio Pacific Interconnect
Rega Maia3 to fronts

Seems to be a slight loss in dynamics/clarity......??

I have tried the SB2 DAC with the interconnects Pacific and then QED2, I seem to prefer the digital o/p and letting the Arcam decode, maybe just because my interconnects need upgrading.

I very much look forward to hearing any comments or suggestions to get back that slight loss in clarity/dynamics.

All I can think of:
Maybe upgrade the Pacific interconnect?
Maybe mains filter - both amps or just SB2?
errrrrmm any settings I may need to check?
