Replacing Manley Neo-Classic 300B


Trying to upgrade from my current preamp and it is a jungle out there.  Looking for improved resolution and imaging.  A sticking point is the attenuator.  The Manley has an Alps Blue Velvet which seems to get only average reviews.  All signal goes through these things.  Shouldn't they be much better.  Researched Khozmo, Goldpoint and others which seem to get great reviews.  It's just finding preamps with really upgraded attenuators is tough.

Looking at the Backert Rhythm 1.3, but it also has an Alps Blue Velvet albeit they say a modified one.

Decware looks very nice, running a carbon composite attenuator and of course all the good stuff, point to point wiring and great parts.

Allnic L-1500 looks promising and has a silver stepped attenuator and nice topography.  Sure, the Allnic L-7000 is probably terrific.....at $16,500!

I know preamp design involves whole concept, but I'm not finding a fully coordinated attack on the whole thing.  Thanks for constructive information.

How bout the new tubed pre from Tortuga Audio, with its LDR attenuator?  Supposed to be a pretty darn transparent attenuator. 
testpilot,

Great idea.  Sent the unit to Benjamin Zwickel of Mojo Audio and he mapped out a plan for that with Goldpoint or Khozmo and other improvements.  Unit arrived DOA to him.  Currently at Manley for repair and service.  So after all that, I'm on the hunt again to fine that premium piece and get off of the preamp carousel.

The rest of the system is done.

Benjamin's assessment was we could definitely improve it, but that some things were inaccessible which left me with an incomplete upgrade.  Thanks for input.

jriggy,

I'll check that out.  Thanks
Look at the  deHavilland Ultravere 3 or the Mercury 3 preamps. It has a gold plated 32 stepped attenuator.
I once had the Manley 300B myself, but my Ultravere 3 blows the Manley out of the water and at half the price.
