No More upgrades to ARC LS25 Mk.1?

I did speak to someone at ARC and that's what I was told. I assume they will still service both Mk.1 and Mk.2 LS25's but apparently not upgrade. Guess they want to sell more of the LS26's.

Yup. I'll contact GNSC. While they may to certain upgrades, I doubt they would do the Mk.1 to Mk.2 upgrades given the parts involved (e.g., new front and rear panels).

JMC:

My bad regarding front and rear panels. That's not it.

Of course I want to improve the performance of the LS25. But, I think the jury is out as to whether the Mk.1 with new 6922's from upscale audio is better or the Mk.2 with the JFET/6H30 is better.

Yes. I understand about the nuances between the Mk.1 and Mk.2. I just wish I had a Mk.2 to use in my current system.

If I were to tell you the Mk.1 is hooked up to a Threshold SA/4e and B&W 802's, would that change anyone's recommendations?

Guess the only real way to tell is to listen!

Thanks all.

Yeah, the LS26 would be ideal for the 6H30.

Might as well stick with the Mk.1 and try some better tubes. And particular recommendations?
