Hmmm, there are still rampant rumours of an impending LS26. . . perhaps at CES? If the pricing of the Ref 3 is any indication, an LS26 may be priced very similarly to the current LS25 Mk. 2, which when new is priced similarly to a used Ref 2 Mk. 2.
Sound of 6H30 versus 6922? It's all in the design and implementation. I deeply dislike the BAT VK51SE, but love the ARC Ref 3. . . and they are both based on 6H30 tubes.
