Never had the HF-1, but I have owned the SR225, SR225i, SR325i, and SR325is. The SR225 or "i" gets my vote. I too suffered from the "overly bright" phenomenon of the SR325's. I thought a tube amp would tame some of it, but not enough to my liking. Plus like earlier posts, the SR225 is the best value of the bunch. If you're eventually going to Grado upgrade, I would get the SR225 for now and then when the right time comes along, jump to the Reference series. If you're lucky used SR225 can be had for $100-150. Good luck.
