Two ideas:
1) go to The Cable Company http://www.thecableco.com/ and tell them what system you are using and whatever you think is a reasonable budget for interconnects and speaker wires. Ask to borrow at least two sets of each and try them for an extended period of time in your system, allowing for break-in/warm-up as needed till the sound doesn't change with subsequent listening. Does this make a noticeable difference?
2) Agree with Mapman, more power is a good thing with many smaller speakers (in order to grab a hold of those little woofers and show em who's the boss. Your amp is older and there are some better ones available used in the $300-750 range. Check on Agon and elsewhere for options. Spending less than this amount doesn't get you much if anything more than you have with the Sugden. Some amps to look at used in this price range include Rega Brio or Mira, NAD C-372 or 352, Cambridge Audio Azur 740A, 640A v2, Exposure 2010S (good luck!), Onkyo A-9555, Music Hall A25.2, Creek 5350SE.
If you buy used, you could resell at very little risk to you. If you find one you like better than your current amp - sell your Sugden to recover some costs.
