Room correction does not work. Usually music becomes lifeless. Why? Because room correction is done for one specific place in the room, might sound ok in one single seating position and horrible in total-general room space.I’m sure it’s been said here many times.
And certainly should have been.
The most cost effective, and outright effective, upgrade after even a very modest outlay on basic equipment is DSP and room correction.
The ‘better’ the speakers the more important positioning and correction become.
But even with truly basic hifi, room correction is a must to get the best out of how little (or how much) you’ve spent.
This is physics word soup mate.Room correction does not work. Usually music becomes lifeless. Why? Because room correction is done for obe specific place in the room, might sound ok in one single seating position and horrible in total-general room space.
I think it is fair to say that you are at odds with everything that has been proven about audio using measurements and blind test. No one will agree with you on this here.Room correction does not work. Usually music becomes lifeless. Why?

Please teach me. How do you do room correction for the whole room and not just for your seating position, where you actually put the measurement microphone?I think it is fair to say that you are at odds with everything that has been proven about audio using measurements and blind test.

This is one of your listening spaces, isn’t it? Your room correction is fighting poor speaker placement for one thing. Putting a PA monitor or dodecahedron speaker in a room corner and firing pink noise is a sure fire way to excite the room modes. We do this for commercial sound insulation testing. But we then average the sound pressure levels across the space using a sweeping motion of the microphone. If we were to measure in a fixed location then move again the values in 1/3 octave bands would likely be different in each location. Start with speaker placement, room treatment for the RT then use eq software as desired.Room correction does not work. Usually music becomes lifeless. Why?

I think this is slowly changing, at least with the better gear from Fosi and some of the more "established" modern Chinese brands like Topping and Fiio, where you can even trade them back to retailers for resale. My personal experience with Fosi's v3 monos and Box X5 phono stage is that I recovered 60% of my initial purchase price when re-selling used on eBay. In perspective that's fairly similar to to the Yamaha A-S701 that has been discussed in the thread, which is £699 new here in the UK and typically sells used on eBay for £400-£450.And it’s something you can always resell or trade-in… a fosi amp is landfill the moment you order it

So true, I tried selling Fosi v3 monos and it was a hard no go. Same thing with small topping dacs, I see poor people on local market trying to sell them for nothing and still no sale.And it’s something you can always resell or trade-in… a fosi amp is landfill the moment you order it
Old vintage amps are doing pretty well, people have created business around importing vintage amps from Japan.Which used monoblocks do sell well on the 'local market', just for reference? Maybe a good tip there for some people.
With the exception of unneeded hot tub chemicals, everything I've sold on FB marketplace, including cheap electronics, has sold. Not all immediately, sure, but if priced right, sooner or later. And I live in one most deprived communities in England.
You wouldn’t normally use a swept microphone technique for eq your room for listening purposes. As Redacted mentions in his post #50, you are just trying to normalise your listening position not the entire room. For commercial sound testing we want as diffuse a sound field as possible. We eq out any antinodes and then use fixed and swept mic methods to get the desired reverberant field. This wouldn’t be normal for home listening unless you are designing a cinema/theatre/ concert hall.What room correction software uses sweeping microphone positions?
That room and speaker position is just fine, no drc neededThose are not PA speakers, not that I have anything against PA speakers, they can sound very good. Wharfedale EVP-X serie is surprisingly good.
The trick then, is to wait for the new brands to become vintage and then sell on 'local markets' !Old vintage amps are doing pretty well, people have created business around importing vintage amps from Japan.
