Upgrading from Supratek Pre to ?

Keep it if you really love it.......unless you want something different.......not nessecerly better.
I've owned Supratek pre and loved it......moved to preamp that better suits my needs and taste. I think it should stop me from looking..........at least for a while.
My last two preamps were both awesome and I could live with either one.

I moved to Dodd Audio and then to Red Wine Audio Isabella preamp with Isabellina usb, nos dac build-in.
I have used Mullards 6922 in both and loved it.
RWA is just a bit warmer then Dodd preamp but its soundstage, image and "Vinyl" qualities with digital source is to die for.
It doesn't have the phonostage section but from what I am hearing, Vinnie Rossi is working on one right now.
As you probably know RWA as well as Dodd are battery powered preamps and his new phonostage will be of the grid as well.
I think Dodd also came out with tube/battery powered phonostage ($1500). In fact, I have asked Gary from Dodd Audio to build a custom phono with step-up transformer for me ....but I will put that request on hold.....at least for few months. Then, I am planning to audition them both and pick the one that suits my taste better.

Dodd Audio and RWA sell direct (RWA has few dealers though).
I can not speak for Dodd Audio but RWA offers 30 days money back if you are not satisfy with their product.

Worth a try and cost you nothing.
