Audio Research Ref 5 and Krell amps

Boisehomes, congradulations on the LS26 and best of luck with it. Not quite sure how you intend to load its main outputs, but please check my posts on this issue. In my case, I loaded my Ref 3 main output #1 with my ARC VS-115 and main #2 with my self powered sub. The rest of the story is in my posts. If you "overload" the LS26, you may experience best roll-off as well as other sonic degradations. If you think this is an issue, send me an e mail and I will explain how to solve it.

Cheers

Thanks Bifwynne. I have not thought about overload! If I have any problems I will send you an email!

Boisehomes, just checked the specs on the LS 26. Seems like most (maybe all) ARC preamps and line stages (including the LS 26) should not have their main outputs loaded with less than 20K Ohms. If you load both output mains, the formula for computing combined impedance is L1 x L2/(L1 + L2). So, e.g., if Main 1 is used for an amp with an input impedance of 300K Ohms and Main 2 is used for a self powered subwoofer with an input impedance of 20K Ohms, the combined impedance would be 18.75K Ohms -- too low.

Bifwynne how do you remedy this? I will be running a pair of subs for sure?

First thing out of the box, call VPi and review with Mike or Harry you problem and path forward plann to so. If they advised you that combine impedance is too low, thereby putting too heavy a load on the pre, they may give you some practical solutions. In my case, I reached out to To Tutay, who in turn built me a custom impedance buggers.
