Help chose : Hafler 110 preamp or Carver C2 preamp ??

Carver and Phase Linear are very detailed but forward sounding preamps.  It’s like sitting on stage as opposed to 7th row center like most preamps, or row 25 like Marantz.. 

I like it sometimes, but listening fatigue is the order of the day.  Conversely, I could listen to Sansui and Marantz all day long.  Some McIntosh and Citation gear as well.  I would lean towards the Hafler.
it was always well thought of.

I am both a Carver and Hafler fan, but would give the nod to The Hafler.  The DH-110 was just a nice, sweet sounding preamp.

I have a Carver and a Hafler preamp in my collection. Along with the Sherwood 6040 amp. I'd say it's a toss-up between the two preamps. Though the Hafler has the pedigree of being designed  by Erno Borbeley (who did all the Hafler SS gear).
