Hello I am new Member on audiocircle,
I just acquire a dac 9 nuprime + sta power amp 9.
The sound is great, very powerful, very dynamic and also 'warm'
I also like the sleek and compact design
but...
My STA 9 amp broke down after only a month and a half of moderate use. The left channel produces almost no sound, just a little treble but no more low frequencies at all. !
I will return tomorrow for warranty repair

Did someone already faced this problem ?
Thank you for your feedback...
