Since the SYS/Lounge seem to play well into your amplifier, I believe an upgrade in TT/Tonearm/cartridge will make a significant improvement in your overall experience. The source sets the limit on what can be derived from a system. Maybe you should consider working from the source back toward the amplifier. That said, one could easily spend as much on a vinyl front end as on electronics (amp/preamp/phonostage) and have a balanced system. I imagine your amp ran ~$1200, the basic Candela lists at $1600, and the basic Suspiro lists at $1200. The Suspiro phonostage seems to be very flexible in terms of gain and loading options. More so than the Lounge. It should mate well with a number of cartridges.
In a vinyl system, the two transducers, speaker and cartridge, contribute the most to the character of a system. Which begs the question: What speakers are you using?
