I have spent considerable time and money at AZ Hi-FI over the past 7 years, going back when Dan managed the shop in Tempe. I recently purchased a ARC amp from Glen and couldn't be happier with the purchase. Glen listens first, considers your budget and tries his best to get you into the right equipment. Its a great shop, low pressure, if any pressure at all, not like some other shops in the valley. I have been an audiophile for 25 years and you must make a stop into AZ Hi-FI before you make any future purchases.
