I am a new member and have been reading the entries made regarding the Vena 2. I bought the amp new in July 2019 and during the past six months have been experiencing a crackling effect through the left channel on all inputs much the same as other members have described. I am now experiencing a fault with the volume control which works fine manually but will only increase in volume from the remote and not decrease. Also, when I switch the amp on from standby the volume control does not return to the zero position. I have emailed Quad but as yet have had no response. Any comments or advice would be much appreciated.
