OK Bretty, here's my verdict based on listening to the first two tracks of Melody Gardot's 'My One and Only Thrill' CD.
Firstly, I reverted the current set-up to single amp and single speaker wire. Amplifier power comes straight off a surge-protected Belkin block via power cable as originally supplied, the CDP and DACMagic are on the Tacima. Initial thought was "Uh-oh". The sound was excellent across the board (based solely on my limited experience): clear, snappy highs, a warm and fullsome mid-range, and a nice underlying bassline when and where appropriate. The presence of Miss Gardot is wonderfully conveyed. So why bother pratting about with other gubbins?
Disconnect the original cable and replace it with the SHB version and let's see...well, I wouldn't say the difference was 'night and day', but there just seems to be just that little bit more of everything across the range. I was pleasantly surprised. Now, that's not to say I would trust myself to blind testing, but the SHB
seems to add that extra 'something'. I guess I could describe it as more dynamic and extra presence. The breathy, lip-smacking sound of Melody's voice is even more..."gggggggrrrrrrrrrrrrrrowwwwwwlllll"
I just did a couple of swaps back and forth on the same section. Yep, arguably that bit more presence and 'ooomph'.
I don't advise it for an already 'bright' system. But for that extra zip and zing I reckon its may just be worth the cash.
