If money is no issue then, get on Further and download as many shows as you can with bands that you like recorded through equipment in which you may be interested. Some stealthable preamps that may interest you are the Sound Devices MP-2, Sonosax SX-M2, and the Aeta PSP-2 and PSP-3. Also look at the Sony SBM-1. Some popular high-end microphones that you can also stealth with are ones from Scheops, dpa, MBHO, and the Neumann km100 series.
Listen to as much as you can and then decide what you like best.
