Hello from Denmark !
I received a B135 a month ago but have had various problems - maybe some of
you have had the same problems:
1) Used as an Integrated amp the sound is rather harsh/agressive
Used as an power amp only the sound is very good. Can this be
due to 'breaking in' ? I have not used the amp for more than 50 hours i think.
2) There is a very distinct and somewhat loud 'hum' when listening to headphones.
I have tried disconnecting everything from the amp and the hum is still there.
3) Sometimes when turning on the amp there is a very loud 'pop' from the headphones
- not from the speakers .
4) When using an empty line-in and turning the volume all the way up, there
is a very nasty noise from the loudspeakers. This is not the case when using
a 'live' line-in (different noise then

) .
5) The frontplate gets 'very' hot after 6 hours or so - is this due to some
special design of the B135 ?
Thats it - im am certainly not giving up on the amp but are looking forward to do some 'work' on the amp and hope
that this forum can help me on the way
NB: My speakers are B&W 683s2 and I use a 'non oversampling' tube fitted DAC as source.
