Hey guys! I'm coming to a point where I'm starting to feel like I should step up my mixing toolbox. I've had the Yamaha HS-50's for about eight years now. Since the beginning I have utilized a home theater sub woofer with them (don't flame, I was young and as I gained experience I used it almost exclusively as bad reference to listen to mixes that had a little more bass). I have a fairly well treated control room (if I do say so myself) and I'm looking to upgrade my monitor source. I have looked into it and I have to say that I really like the sound of the HS-10M when paired with with HS-50's. But am I wasting money trying to upgrade an already mediocre system? Should I look to the next system and move away from the little bookshelves that have treated me so well? If I was to upgrade, I would like to stick with 5-6" speakers with a sub again. I've always felt them to be a little more honest in the low/low-mid than 8". I know someone (a member on here actually) who has a pair of Dynaudio BM 6A's for sale for around $500. Better investment? I'll have to spend more money for an amp and a sub (later on), but I record a lot of local bands on a regular basis. Thanks in advance for the advice, ladies and gentlemen! I do rep (if that's still on this forum...).
