I was wanting buy a REF3 but after speaking the Dave Gordon and Calvin from ARC at RMAF, I will wait to buy the LS27. The implimentation of improvements they gained in the design of the REF5 have filtered their way into the design of the LS27. From what I understand the power supply alone is better than the one used in the REF3. My local dealer has just sold his LS17se and feels it may rival the performance of the LS26. Those folks at ARC are doing some really great stuff these days.
