Integrated.... Hmmmmm.... If we're talking used, this (maybe...)
The problem with Levinson gear is that it is well known the power supply section in caps and rectifiers will need replacement, and the other caps in the signal path will likely need replacement as this unit is fairly long in the tooth now, so maybe not exactly a budget option, unless you can find one with low hours.
If NEW is on the menu, then this!
Below - two of these mono amps!
From Schiit's website, they write this:
Freya+ and 2 Vidars, $2347. Now you're getting into serious capability, with Freya+ and 2 Vidars run in mono, for 400W per channel. This system is serious overkill, but sometimes there's no dose like an overdose!
Choose Freya+ and 2 Vidars for:
Exceptional power, headroom, and flexibility
The highest performance speaker-driving system from Schiit
Perfect match to Gungnir Multibit in size, Yggdrasil in width
The tube preamp will be awesome. When you have some fun money, perhaps buy some Telefunken or Amperex vintage tubes to sweeten the sound. In any case, happy hunting as the saying goes, and have a Happy New Year!
