New on audiogon

Just puchased,
Wadia player and Einstien light power amp
Which will work best according to wadias manual without a preamp
Now i need speakers and speaker cables that might be a great match up
So I can start listening
My musical tastes include , classical and acidfolk primarily.
Hey tastes change!
Any suggestion, thoughts and input greatly appreciated.
I also was wondering if buying 15 year old speakers is wise or not,
Would they still be good for another 15 years
Will there resale value continue to decline ?
