PS Audio BHK Pre Amp and Herron VTPH-2A Phono Pre Users


I just purchased a PS Audio BHK pre amp.  I am moving to the BHK because I need to start using XLR cables for long runs to my power amp.  

When using the BHK with the Herron VTPH-2A phono pre, the sound is flat - for want of a better word.  When I use my Herron VTSP-3A(r02) pre amp with the VTPH-2A, the sound is wonderful.  I'm new to tubes.  I think I have an impedance issue.  Anyone else using a Herron phono pre with a BHK pre amp having or had a similar experience.

@three_easy_payments  You are.  With a more direct title and question, I was hoping to get a definitive answer.

I'm OK buying a different phono pre as a last resort, but I'd like to find out if I'm doing something wrong or if there's any way to get the Herron to work with the BHK.

I've considered the Parasound JC3+, PS Audio Stellar, and Sutherland Little Loco.  I'm leaning towards the PS Audio Stellar as I know it will work.
