The high fidelity equipment is concentrated in the rear of the store, with the high-end stuff concentrated in the final room at the back. The sales staff is knowledgeable and sometimes willing to dicker. Ask about discounted demo units. They also do authorized repair work on numerous brands.
Huppins operates a huge phone and Web business called OneCall, which often offers good deals; but for hands-on shopping I prefer dropping in to talk with the folks there.
Be aware: Huppins closes on Jewish holidays and for Hoopfest.
