In my experience with a metal tweeter speaker, you will end up spending more to tune them into the sound you want, than it would cost to sell them and replace them with a warmer speaker. In my case it was a good result because I was happy to use tube power amps (not just a tube pre) and play around with various options over several years. I gather from you post that you don't want a journey just a change. So again sell the speakers as difficult as that may seem, and buy warmer speakers.
Need a warm amp for bright speakers
So when I bought my system some time ago I made some mistakes being this the first time I ever ventured out doing this. I bought Paradigm Monitor 9 v5 and a Pioneer VSX21TXH. Surrounding speakers aer all Monitors backs are Titan v5 and center is a 290 I believe v6. The SVS kills though. The fronts do get very bright when pushed especially with metal that I listen to and it is VERY BRIGHT. Without redoing my whole system is there a way I can tame this problem? Use my Pioneer for maybe center and rears and processing and a dedicated amp for the fornts? If so what should I shoot for? I hear NAD is a good warm amp. I don't want to sell or get rid of the Paradigms because getting all new speakers would be far costlier than a dedicated amp. However I am a little skeptical that I can solve this with just and amp. All ears open for a relative newbie.
