sansui or yamaha

Ih8this1, That's a blast from the past for me!

I owned DCM Time Windows and Sansui gear back in 1976. I still have my TU-717!

I tend to agree with Yogiboy. if my memory serves me, the Sansui/DCM combo had a somewhat colored sound, and I thought that may have been a characteristic of the Windows. Have you tried other amps with your speakers?

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?
