I have used the NBS for many years and have gone through most of the different renditions. I currently use the Monitor O throughout my system. I have heard no other cable that even comes close. Most other cables sound like listening with ear muffs on in comparison. Each rendition has been a definite audible improvement. I have not had the chance to do a direct A/B with the Nordost Quatrafil throughout my system which a number of reviewers seem to like (HP for instance). I find, however, he oftentimes prefers a rather lean (i.e. anemic) sound. I guess my ears just are not as golden as his. I did have the Transparent XL Reference and found it to be considerably slower than the NBS. I was like some of the tube sounds of yore. I believe it is quite important is to "voice" your system throughout. Each piece of associated gear has its own characteristics and will have an effect on the overall end sound. They culminate in room interaction for the resultant sound you hear. Therefore what is the ideal in a single piece for Joe might not be the key for Fred in his system. All pieces of gear have their own sound (flaws). There is, therefore, no ultimate piece for everyone and the perfect match for every system. You must voice each piece to the combination of all the rest of your total system. Each time you change a piece you wind up readjusting the rest to reach your endpoint of satisfaction. Ain't it fun!
