Thanks for the response.
In this context, the question is: can I find an interim preamp for $5K or less that would in some aspect outperform the MyTek?
In that regard, I would take suggestions for something that is "more neutral", but I would also consider other preamp suggestions that might "have a sound", as well, if the overall sonic benefits are positive to me above and beyond the MyTek.
If I can’t "do better" for $5K or less, then I will just hold out to get a Pass Labs preamp to go with my existing XA160.8 monoblocks.
