This is just my opinion. Take it from some one who has done many litening tests. If a dealer can not be bothered to go to the trouble to set up demo's then they are not going to get my business. Most places I have gone to are more than willing. Sorry I have never heard of spearit but I think NAD makes some very nice stuff for the money.
