Thank you all for taking the time to post your replies, they have been very helpful. If money was no object, I am leaning towards the PA Venustas. However, the discussions are now making me think again about the interconnects I have almost settled for - Nordost Valkyrja. I find them extremely clean and revealing, which perhaps is at the root of my problem. What makes matters worse is that I've been offered a really good deal on them and since I haven't heard anything else that provides the same level of clarity, I am reluctant to give them up. This begs the question, are there any cheaper I/C cables out there which offer the same type of performance as the Nordost's but with a bit more bass weight/warmth?
