Hi all Audio Circle members.
Here are my two pairs of GR Research OB.
(V1 and V2)
Both OB are modified (A little) from the original design.
Very happy with both of them,
even and because they sound different from each other.
Both of them are easy to drive with my Decware SE84C= (2wpc)
and my Niteshade Audio NS-10 SEPentode (10wpc)
