I'm now running my Titus 202s with a Musical Fidelity A3CR. Very nice. I also use them with a vintage NAD 7020 receiver for 2 channel A/V. I like this combo for video but not so much for audio. The old NAD has a lot of bang for its size but does not bring out the detail the Titus are capable of. The Titus also pair well with my M&K V1-B sub to fill in the bottom end. Going off a recommendation on the ACI site for their subs, I plugged the ports in the Triangles and adjusted the low pass filter on the sub up to about 80Hz in an attempt to shift more bass load to the sub...this worked very nicely and produces a smoother transition to a top notch bottom end.
