sansui or yamaha

I'm afraid that I disagree with both Yogiboy & Kennythekey. I have a vintage Yamaha CA-2010 that I think lives up to its name of "Natural Sound Amplifier". I do not find that its sound is thin at all. In fact, I need to plug one of the bass ports of my speakers to contain the bass.
Sansui vintage amplifiers are beautiful to look at - fine workmanship of the past - but they are well-known to have much richness in the mid-bass. This fact is well documented. If you like this type of sound, great for you!
I personally prefer the well-balanced sonics of the Yamaha amp. YMMV.

The AS2000 is a neutral amp. Definitely not thin sounding.

I have the AS 2000. No complaints.

Bombaywalla is kind in writing "much richness," where I wrote "colored sound" regarding the Sansui/DCM combo.

It comes down to the sound that you're after, and 70's gear (not everything) leans towards rich/colored sound when we're talking Sansui, Yamaha, etc.. I think the Yamaha SA2000 is new and aimed at the 70's sound? That's all I know about it.

I also think that if you're after "natural" sound that may be mistakingly referred to as thin, you may be disappointed in what you hear. Achieving true natural sound comes at a price, and may not be your cup of tea when listening to 70's music.

What kind of music do you listen to?

thanks everyone for responding as regards to my music preference I do listen to a lot of classic rock but i also like the blues it just kinda depends on my mood that day anything from Hendrix to Norha Jones,Joss Stone,black keys,Adele
