Definitive Technology BP2000 vs BP7002

I own a pair of Bp2000s and wanted to know if going to a pair of BP7002s would be a upgrade in both sound and build quality. The BP2000s I have had for almost 20 years, and I know technology has come a long way in that time.
Yes, Difinitive technolgy BP7002 would be an upgrade, audio technology just like vidio technology they get better everday.
Since audio sound and music perception is entirely imaginary (you can't touch or see a musical image), what and how we hear is formed only in our brains and is not measurable unlike video.
