Good luck with your amp, personally I would not buy a VTL product new or used ever again. Several years ago I purchased a VTL Stereo 50 used from the original owner. I had all of the original documentation, the warranty was a"Transferrable Lifetime Warranty" provided that VTL was informed of the transaction. I e-mailed them with the serial number and my info upon receiving it. Unfortunately the amp failed a week into owning it. I contacted VTL to hopefully obtain "Warranty" service and was rudely told "we don't do that anymore" in reference to the "Lifetime" terms of the warranty. When I explained that a warranty is a contract beteen the manufacturer and the owner they said "sorry our warranty is five years, non transferrable.". I spoke to Luke Manley who was also quite rude and basically didn't care that they refused to honor a written warranty that implied "Lifetime" as the duration. I interpret lifetime to be a lot longer than 8 years. I ultimately sent the unit in for repair at a cost of $250 plus shipping, $250 to replace 4 small input caps ? Rip off ! That's half of what I paid for it. I'll admit it did sound nice but it failed about 9 months later, it needed an output transformer and they wanted to repair it by replacing both transformers at a cost of $400, no thanks. Needless to say I dumped it on eBay for $350 to someone who wanted to repair it and cut my losses. I've had a Sonic Frontiers amp in use for about 8 years and it's been rock solid. I did have a tube failure that led to a blown resistor and even though Sonic Frontiers had ceased operations Anthem offered to repair it under warranty. What actually happened is that Anthem sent me several cathode resistors after some further troubleshooting. They figured that being a simple repair a local tech would cost less than shipping to Canada and back but after I explained to them that I was an assembly tech and soldered daily they sent the parts directly to me. It was literally a five minute repair. It's important to note that a bad tube caused the failure, technically it was not a defect in the amp or it's workmanship so they could have rightfully said "sorry" but they sincerly wanted to help me get up and running ASAP without the snotty attitude I received from VTL. I would not hesitate to buy an Anthem product in the future whereas VTL lost a customer for life.
