a subwoofer can not make the sound sounds punchy. i m not a great fan of punchy sound, what i want is just normal energy of music force. i go to live concerts, different concert halls quite.often.
My current setup is a result of a long period test, includes, listening room enviroment adjustment,
changing different computers, different computer power cables, usb cables,even power cable plugs,
different interconnect cables, speaker cables,.different software players, power conditioners, different loudspeakers, etc...
the current setup.is what i think.the most neutral , honest sound system, within my ability and the price range i can afford.
it could have a lot more possibilities of compoments combinations, but i doubt changing others would let the system with Ciunas in it sounds energetic enough, based on my experience.
i really hope Ciunas would remain as my choice
,anyway i will try more usb cables, i am still waiting for the usb adaptor, which could keep more music details. and i hope another 50-100hrs would make a lot difference.
