To answer some of the unknown's raised and to give a brief description of the set up which may help.
I live in the countryside with the nearest house a couple hundred metres away.
It’s a 10 hour drive or a plane trip to any audio shops, so home demoing is not an option.
I haven’t seen a loudness switch on an amplifier in years. I did have one on an old Marantz in the 80’s.
I have never heard super tweeters but would be interested in listening to there effect next time I’m in a HiFi shop.
I don’t have a proper decibel meter but I did download an app which reads between 55 to 70 from the listening position, music piece dependent.
Front of speakers are 1 metre out from the wall, 1.8m apart and 2.8m to the seating position with the seat approx. half a metre behind to the wall.
Floors are timber on battens fixed to concrete with no rug on the floor.
The wall room treatments (R.T.F.S) have made a huge difference to the sound coherence and clarity. These are placed on the front and back walls with a small panel at the first speaker reflection point on the two sides.
Prior to this, the sound was muddled.
By adding/removing one isolation/diffuser piece at a time and readjusting positions down to very small increments, which took months in finding the right positions and balance.
It wasn’t straight forward and frustrating at times gaining a certain sound aspect and losing another.
I did find the volume level didn’t need to be as high after the room treatment.
I will have another tinker about and see what changes.
One thing that hasn’t changed prior to or after the room treatment, is my slight tinnitus being a little louder in this room compared to the bigger room with the TV.
I have been working on the fundamental basics of the system- Power, Isolation and cables feeds and they all have made a better difference, some more than others.
Mains power is dedicated 6mm (9 AWG) feeds with one to a Gigawatt PC3 SE power conditioner.
Cables are a mixture of Gigawatt, Final Touch Audio, Tellurium, Vermouth and Studio Connections.
Isolation racks are AG Lifter, with components on RevOpods and Stack Audio isolation feet.
The Buchardt Speakers have Stack Audio footers beneath them on SolidSteel SS filled stands with bamboo board capitals.
Is my thinking off track, with the Buchardt's not being a high efficiency speaker that require a bit more oomph to reveal the same details at lower sound levels, or the Kinki Studios amp not giving the Buchardt speakers enough push at lower levels especially in my small room?
