I have Reference 18's. when I purchased them I had called Craig Oxford to discuss the speaker and he said: "You have our test mules!". He went on to tell that as of the time I bought them, they had the absolute best and newest components.
I run them with Levinson 33's and 33H's, and a full Levinson reference frontend. 5 years now, and I have no desire for different speakers. No regrets. I can't hear any comb filtering, and the sound is very dynamic. Large orchestral works lose nothing during loud passages, all instrument always have their own space. I'm coming from large apogees, Infinity Betas, and other high end speaker offerings. The "pipes" are as good today as they were when I bought them.
