You could make a post here looking for of BH's in your area with headphones to try. It's always nice to meet other fans. You may also want to look up local headphone meets in your area. The big headphone sites have sub forums for meet ups. If you have a dealer local, and if you already have an amp, you could bring it in and try it on site. Lastly, you could order a pair with a return policy and if you don't like them, send them back.
I rolled a lot of headphones before settling on what worked best for me. Headphones are very subjective IMO and if possible, you should try them in your system before committing. Just my two cents.
