I use Ecosse 2.3 for my HF and IXOS 6006 for my LF (bi amp). They are a very good combination.
Ricky used to tell me that he doesnt believe in speaker cables. But when he came to our house to watch our demo disk project, I was experimenting on using the IXOS 6006 for my HF. It was too bright and many of the scenes we were watching were ear piercing. So I switched back to Ecosse 2.3 for the HF. And there, it was back to the crisp, clear sound (same scene) he used to hear in my setup. But he also noticed that some details were missing compared to before. I actually was experimenting using my IXOS 606 PAkora for the LF that time. Thanks ricky for your observations.
So my discovery, based on my personal experience this month experimenting w/ 4 speaker cables, is that bright cables like Ecosse and IXOS 6006 are suited for HT. It brings out the details and crispiness you need to hear from your speakers. Also good for instrumental music where you need to hear the HF and crisp mids.
Sweet sounding, laid back, etc, whatchamacallit cables are good for music, particularly vocals. This is my experience with IXOS 606 Pakora, VERY nice for audio. Lush vocals and very rich mids, wide soundstage. The difference was noticeable right away coming from using bright cables for a long time. I also experienced this with my BADA speaker cable, ito very laid back, parang polished yung vocals.
