At the moment I`m using Superlux HD-681 (mkII filter mod + custom pads+ recabling) with Aune T1 as DAC (upgraded ELNA SilmicII capacitors and Siemens E88CC goldpin tube).
And I`m feeling that my cans have hit the wall in soundstage depth compared with my external speakers after changing to Siemens E88CC tube.
So, I have started to look for new cans which would have similiar sound & soundstage as HD-681 but with better depth.
Any recommendations? Max price tag would be around 200 USD / 150€ ...but little extra allowed if it is really worth it.
Hope someone can help me out :)
