Amplifier for Tekton speakers

Nguyen, what speaker and interconnects are you using? I have used
Kimber 8TC speaker, PS Audio Statement, Goertz Alpha Core AG1, for
Interconnect, Cardas, Silnote Morpheus II, Alpha Core Sapphire silver.

I should also mention that I also have the Eastern Electric Mini Max DAC
currently connected. I haven't tried the Metrum Octave yet as it is currently
doing duty in my main system. I've been using the stock power cord.

Monster THX Ultra 600 interconnects between CD player Lexicon RT-10 and amp Almarro A205. The speaker cables are Acoustic Research 12-AWG (very generic) with banana connectors both ends.

You have quite an impressive equipment list!

Forgot to mention have to get Sophia Prince Mesh 300B for Paramounts.

Bottlehead Paramounts with 300B tubes with Lore and Eastern Electric DAC as preamp also.
I use Logitech Touch with Stereolab Digital cable.
Great sound. Even my friend with huge Pass Labs monoblocks likes it a lot.

Nguyen, I suspect you should find warmer speaker and interconnect. Cary with Tekton Lore is superb, likewise Primaluna with right tubes.
