Depends on your tastes. I prefer a Crack + Speedball + a few other mods and some good tubes. Valhalla 2 was a little too lean and not dynamic enough for me, plus a bit grainy in the upper mids. But it was neutral, fast, detailed, and had a good sense of space to it. Still very good for the price. Lyr 2 might be OK too, but I only heard the pairing briefly at RMAF.
