I think that the MicroZOTL MZ3 is the very limit of my budget. Last I looked it runs about $3700. I can do that, but if some of these other suggestions come in under that and fit my criteria, then I will choose wisely. It's a big decision.
Currently the Threshold is being refurbished at Vintage Amp Repair. When I get it back and again listen with the Freya+, then I hope to have decided on a preamp with the ergos and sound I'm looking for. Everyone has been a great help with your suggestions. I will post my results when I take the new plunge.
