I use 10 Behringer Truths in my 27 channel VTPO. I have purchased these gradually over a period of 4 years, and not had one quality, or reliability issue with them even though they come from 4 different batches.
I have some friends who also use the matching sub in a VTPO contexr, and they have had zero issues and the same with their coterie of Truths.
You will often find dealers who put s... on Behringer due one reason, and its a major one for a business. The reason?
Behringer do not provide trading terms for Behringer stock. The dealer doesn't get Behringer's money to play with for 60 days (if you purchase on the 1st and pay on the last day of the month following) like they do with other manufacturers/suppliers. So, in these days of tighter and tighter business conditions, I am sure that you will find that there will be quite a few dealers who will not wish to stock Behringer, and consequently they will push whatever product they have in stock (that the dealer might have to pay for shortly, or that they have already paid for), or they can avail themselves of trading terms.
