We have
1)Yamaha sound bar Yas -207( comes with a subwoofer) in living room. Bought for 27k
2)Q acoustics bt3 ( active bookshelf speakers) bought for 36k in my dad's room
3)Genelec 8040b with genelec 7060b 2.1 bought for 3.3 lakhs in my room.
When comparing the bt3 with Yamaha the bt3 sounds good ( lesser bass though) according to me and my mom.
But My dad likes the Yamaha sound bar more than the q acoustics bt3 . And my parents il are the end user for both the systems coz i almost always listen in genelecs.
That's how choices vary.. which makes it really difficult to make a list .
Different people like different systems.
You will surely make a list of gear under each budget.
Just like many other websites like what HiFi do.
But people might not agree with your list as their views will be different.
Rating speakers on sound quality depends a lot on the amp, source used. Some might use a expensive amp to listen and some a cheap amp. Rating speakers and amplifier separately will be a problem because of this.
I have a crown xls 1502
@tuff knows how good it is.
But people have come to a conclusion that it will not sound good without even listening to it, just because its a amp built for professional use.
You can add the crown 1502 amp to your list.
There are n number of factors affecting people's choice that's why making single solution for everyone one will not be possible.
I think you should categorize the systems.
Like system for good bass ( but sightly muddy) system for tighter bass but less deep.
System for movies.
System for music.
System with warm/neutral/bright sound.
System for use with subwoofer.
System for use without subwoofer.
System for use with compressed audio.
System for use with high res audio.
Subwoofer for treated rooms/ untreated rooms/for movies/for music.
Amp for speakers with low impedance
Bright/neutral/warm amplifiers.
AVR with possibility of adding a power amp.
AVR without pre outs.
Speakers for use with AVR.
Speakers with good WAF( good looking speakers)
speakers mainly for sound quality ( looks/size don't matter)
Speakers for dedicated home theatres/for placement behind screen.
Easy to use speakers.
Active speakers.
Professional systems which works well in home use.
Studio speakers which work well in home use.
DAC- neutral/warm/bright.
Create certain categories and gradually to add systems to each category.
Your motive is right.. but IMO you have to take different approach.
