Comparisons of the Pass-Labs XP-22 with the CODA 07X ?

There are a few others on A'gon who found the 07x noisy and few others who thought we were hearing things. My unit was actually stripped to the bare bones and all parts except the case was replaced by CODA. It improved the noise issue but was not pure silence like I want.

One thing you can leverage for your preamp needs is the RCA/XLR toggle switch on the front of the #16. Try the Schiit Valhalla 3 OTL/OCL on the RCA input of the #16. You have 15-days to try this at home on demo and the unit costs $500. I think you may be surprised at how good that thing is. It only has 1 RCA input and 1 RCA output. However, I paid $800 to get Space Tech Lab in Canada to build me a great RCA switch so I have 4 RCA inputs going into the Valhalla 3 OTL/OCL.

The circuit on this is so clean that the unit does not need break-in. Just let the tubes warm up. I use NO FEEDBACK option on the Valhalla 3.

My complaint was similar to @yyzsantabarbara , though it was not noise that you could necessarily hear. It was just that backgrounds were not dark and everything had a little haze around it. I did some research and the big upgrade to the next generation included transistors with a huge decrease in noise. I suspect the newer version was/is much better. 

I followed that with the Benchmark LA4. I liked this preamp, and it was great for low volume listening, but it is just too stark and sterile for my tastes. The Pass XP-12 was wonderful.

I only switched away from Pass/Coda when I fell into a deal on some Audionet gear, a whole different ball game.

"I'm surprised that the 07x sounded noisy"

From my reading this was only an issue on the first gen models, they solved that issue in the second gen, with other updates. 

Hi All,  Thanks for your inputs and suggestions.  I think after some reading, that rather recently, CODA went with new notably lower noise FET's and I believe they use them in the #8 and #16 amp front ends.  I wonder if speaking with CODA they could allay my concerns about quiescent noise in the 07x.  Pass uses NOS Toshiba FET's that have long since gone out of production, and my XP-22 is really quiet.  As I understand it, they bought up a quantity of them prior to their ceasing production.  I'm headed to the Tampa Audio Expo today, so I'll try and contact CODA next week.  I hope they will discuss the 07x noise with me since I already ordered the #16 amp.  

@glennewdick I think that you are correct. I would like to hear the latest generation.
