Wow, What a spectacular shopping/learning experience. The amount and verity of different equipment to listen to is astounding. Dave’s knowledge and passion are contagious, he knows so much and is willing to share his knowledge as well as let you experience the difference in sound from each of many vendors. One of the things that amazed me was how different the sound is when changing just the amplifier. Listening to different equipment is the only way to make a knowledgeable decision about how you are going to build your system and how you are going to spend your money. Dave’s listening rooms and his willingness to let you participate in experiencing the sound make it very comfortable and enjoyable to listen and learn.
