Preamp Suggestions for hot-rodded Odyssey Khartago?

gochurchgo OP
so would it be a dumb question to ask if a passive would work given Odyssey’s low impedance?

No not dumb, it’s said Odyssey’s are hi gain (low input sensitivity) this means they are the ideal candidate for a preamp with no gain, like a passive.
But! the problem is they are only 25kohm input impedance which is not great for a passive preamp, you need at least 33kohm or higher for a 10kohm passive to be impedance happy.

So what you need is a passive preamp with an active "unity gain" buffer, the closest I can think of commercially with trial period is the Schiit Freya preamp. at $699. designed and made by Mike Moffat of Theta fame.

It’s 3 preamps in one with a very good 128-step relay volume control, remote control, xlr and rca inputs and outputs,
Mode 1 passive with no gain
Mode 2 Active discrete fet buffer, gain of 1 ( your most likely one)
Mode 3 Active tube with gain of 5
And you can return it if no satisfied.

"Mode 2" could very well be a copy of the Nelson Pass B1 buffer, as it’s also just a couple of fets and simple like this, but it "looks" as if Mike Moffat has gone a step better and dc coupled it, which is better, as I can see what looks to be dc servos around those fets with no coupling caps.

If I was going to go that route it would be the STP-SE.  I know that works great. Look for used or demo.  Try Hi-Fi Heaven they always have"demos."

@georgehifi I originally bought the Freya/Vidar and the Freya was kind of a mess. Horrible microphonics, the tubes we’re unusable, and I agree with some about the clicking volume.

As others said, and I echo this as well, that the JFET and tube stage sounded the same. I don’t see how they can sell a tube amp with obvious issues. But some people love theirs so...

i have no no doubt they will get it worked out and I applaud their quality to dollar ratio. I just had a bad experience and don’t want to do it again. I truly wanted to be in love with the combo and it didn’t happen. 

That's a shame  gochurchgo, I heard they did have a bad batch of Chinese tubes that were microphonic, but as you said it's the fet stage that would have been the one for your setup.

 I suppose you can look for a used Pass B1, trouble is they are 1kohm output impedance not 75ohms like the Schiit, with no dc servo and capacitor coupled, I always prefer direct coupled, with no capacitor in the signal path, to me the best cap is no cap.

@georgehifi Thanks. You almost make me want to try one again. The release of the Vidar was what got me thinking separates in the first place. Which then lead me to Vincent, then AVA and then Odyssey. All told, I'd rather get a Candela but I am reconsidering.
