Hi. I do understand your concern for biased opinions. I can only give you my feelings on how I was pleasantly handled on many occasions. I have purchased "many" peices at his location.I was always treated like a freind and customer.
I had a chance to audition the MBL top of the line Monos with the 30k loudspeaker (# ? ),which was truly incredible to hear. Unfortunately I couldn't afford them at the time.
To be honest I think we all have biases when it comes to music,because we all hear things differently.Good Luck
