Are 90's mid-fi units as good as hi-fi from 80's

Speaking in general( to sound improvements of late)---(and in tvs,no less) I have had two new tvs in the past 12 months. #1 was the Sony xbr-6. This thing, for what it, is is pretty amazing;and for such small speakers---ok, no bass below 200hrtz but such an amazing mid-range.---Then on to my Pioneer plasma; not quite the mids as the sony but it goes much lower.
I'm sure they both use some kind of processing to widen the sound stage to the rooms edge.
The only reason I bring this up is to assume this technology has to do wonders to the "mid-fi" products of today, in general.
I own Sophia 2;s and know what pretty good is.

Are 90's mid-fi units as good as hi-fi from 80's
Are we making any advances or are we just going around in circles (that get more expensive over time)?

I have VSP TransMOS power amps and one Amber Series 70 power amp from the '80s. The TransMOS listed at about $1K and was considered underpriced; that's about $2,000 in today's dollars. With the emergence of US and Brit-designed electronics manufactured in the Far East, there are some seriously good amps now for less money, adjusted for inflation. For example, I suspect the $1100 hybrid Vincent would handily beat the TransMOS.

As to the original question, I'd say no, a lot of '80s high end was pretty good, and '90s hi-fi would have demonstrated incremental improvements, but '90s mid-fi wouldn't have been as good as '80s hi-fi.

Today I think the situation is different. Class D and other switching amps are coming into their own, and as they become more musical they bring new levels of speed and clarity, and noise floor so low as to be unthinkable a few years ago.

Some of the integrated amps from $500 to $1500 today offer tremendous value--Cambridge, NAD, Onkyo A-9555, Musical Fidelity, PeachTree, Vincent, etc., and they probably all whomp most '80s gear.

For example, the Cambridge Audio 840W is about $2400. Adjusted for inflation, it's just a little more money than the VSP Labs TransMOS 150 was, yet it's more powerful, has a wider bandwidth, and (I think) has a better s/n. I haven't heard this Cambridge, but I've heard others, and the 840W was an Absolute Sound 2008 Product of the Year. I suspect it'd handily trounc

Interesting to see the responses here-sort of age based-i grew up in the 50's with tube fisher, marantz and garrard tt--every decade since then has improved tv and easier maintenance and operation ( read that convenience) and quality of sound degradation until, voila, the ipod....nuff said.
