Well, 8 months later and I'm still running the Harbeths. They've grown on me. The key is I have to listen to them at above-average volume to get the sounds that make me take notice. Saw a teaser about new Totem Buffalo speakers but still nothing on the Totem site. So, for now, I'll heed the advice you've all offered and look to implement a dedicated amp/integrated amp with a home theater bypass. On top of that, I'm looking to replace my Bluesound Vault and external Schiit DAC with one of the new HiFi Rose streamers with the Sabre DAC.
The testing/auditioning continues. If I had an unlimited budget it might be much easier!
