Since I run a '922, I have a question:  The "quarter S-unit" isn't my
concern.  But would the added cooling + heavy duty XFMR provide added
headroom?  In other words, I know it won't affect the signal strength
much, but would it be cleaner since it could handle higher peaks
instead of flat-topping & splattering (given the same drive level)? 
Also, which Peter Dahl XFMR would work?  I looked at their website and
found nothing for the '922.

Thanks and BR,
