I run a very similar setup, as my signature shows. Using the Startouch ABY, I have no noticeable volume or tone loss, and no ground hum. Like already mentioned, two amps does give you a bigger, fuller sound. Personally I've found that running my Naylor dirty, and my Twin clean, I get a great rock tone that allows better definition of notes/arpeggiated chords.I run a Twin and a Naylor ABYed. One tip (the most important,imo) is using
a good quality ABY switch with an in phase/out of phase switch. I really like the Radial Switchbone, but there are a few others that have the phase switch.
If you are running two similar amps (Twin and a Deluxe....ect) you may
not need phase correction, but Fender with a Marshall, or Vox ...look for the phase switch and you will hear a huge difference.
I used to run a tri-amp setup.
Fender Deluxe Reverb for cleans (22w)
Splawn Competition for rhythm (25w)
Cornford Hurricane for leads (20w)
.. Well it kinda worked but I just ditched it all for a single channel head and cab. Somehow works better.
Wall Of Freaking AWESOME tone...I love the Naylor(ev38) with a clean Twin !!!! I have tried a ton of amps, but nothing has ever come close to this combination...love it. +1 to NaylorStrat for bringing the TONE !!!I run a very similar setup, as my signature shows.

Both amps at full tilt? Wall of freaking sound!
