I've found a bunch of threads related to high-end amp switchers here. There appear to be some nice ones around. One thing I'm still wondering...which is the most transparent amp switcher around? I used to have a Framptone Amp Switcher (two amp model) and it was quite good but I still noticed that it took away some of the mids compared to when I plugged straight into the amp. Are any of the other units more transparent than the Framptone? Ideally...I'd like to be able to switch between 3 separate channels. One channel would be on my Peters Polaris (single channel amp) and the other two would be the two channels on a Vox AC15H1TV but I could potentially live with just a two-channel switcher. There don't appear to be that many that can do 3 channels. Another question....on the Lehle Dual...they indicate that the T output is not electrically isolated from the B output. If I used ouputs B and T to switch between the two channels on the Vox would I experience issues with hum? Is electrical isolation only required when switching between two different amps or is it necessary for switching between two channels on the same amp as well? Thanks.
