@chungjh The offer from a forum member to visit is a very kind offer and is a very good opportunity that awaits you.
An experienced enthusiast and like minded individual is willing to share time with you in your listening environment, this is a very fortunate turn out, and the 'one to one' time together should be remembered as an invaluable experience for a very long time.
These types of interactions are my regular participation, I don't find being shut in a room by myself, as my only HiFi interaction of any great value.
It is for me much more enjoyable when shared as a community and visits and visitors are the norm.
Now with my vast experience of such types of encounters, there is a need to arrange the room correctly, there will be a requirement for a special room treatment, to be placed in a very easy to reach location between the listening position and the speakers, a selection of Biscuits is the only requirement for a very special room treatment for these occasions.
Enjoy.
