If you're considering spending this kind of money, I'd invest in a trip to a city with suitable high end shops so you can personally decide unless you are not going to buy new. BAT is an esteemed brand and for good reason...high build quality and unsurpassed customer support. With this level of equipment, opinions you hear are based on subjective musical preferences that are individualized. I doubt if anyone told you the BAT gear is unreliable or the company turns its back on you if you need service. I've owned one BAT pre and it was a terrific piece VK5i.
Good luck,
