Edward, I love tubes, but w my NATs tube amps sating my desires there, I'm not minded to run a tubed dac or phono
Indeed I've never been convinced by any non SS phono or pre
So, the Formula as a non tubed dac more likely up my street than the Scala
Can you compare and contrast the attributes of the Dac8 and the Formula?
Atm, I'm putting serious consideration into going down an initial but also final destination streamer/dac, and I've been well and truly spoiled by exposure to Barry's exemplary SGM/Dac8
What would swapping in the Formula bring significantly additional to the table?
I'll keep in contact w you and Sablon Audio re any future possibilities re this combination
With my new £40k audio room truly emptying my upgrade budget, this will have to remain a project, but my mind is considering the practicalities
Sooner rather than later we will be delivering an Aqua Formula demo unit to Barry. Barry has great ears and I value his comments and observations way over mine !
