    I ran that rig and you shouldn't have any problem driving the 728. I thought that would have been the "ultimate" SVT type setup, but I ended up hating that preamp and the low end was a mess with the 728 (not the 728's fault).

    The SVP-CL will drive a power amp to full power so long as the amp has an input sensitivity of .775 Volts which is the same as 0dBm if I remember correctly.
    I can't get the Aguilar site to open to check amp specs
    I do know that the only modern power amps I can find that will meet this spec is Peavey IPR or Crest.
    I believe that later model SVP's had a higher a 1.0V output.
    PM me if you need the schematic to change the older units to 1.0 Volts.
    Mr. Tiers has a shop he recommends for this mod and the price is approx. $175.

    The input senstitivity on the DB728 shouldn't be a problem - it's pretty easy to drive, so no issues there. I had problems with the SVP preamp in general - the way it was voiced and the EQ. The low end just seemed to boost a lot of sub lows - it was a bit better with SS power, but I still didn't like it - the DB728 adds even more of that massive girth that we love from tube power, but with all the deep lows out of that preamp, it was kind of a boomy mess. I also found that preamp pretty bland - extremely clean and not very tubey IME - hard to get a good sound to cut through - no real growl or grit to help bring definition to all the low end, no real character. I had much better luck running a Sansamp RPM into the 728 - probably my favorite - Aggy 659 was also good (I actually had a pair of 728's at the time and a bunch of preamps including the RBI, Ashdown RPM, SWR IOD, Aguilar DB659, etc.) - they all worked better than the SVP which went back during the trial period.
