Upgrade Quandry - Who's on first?

Tobias:
Why are you down on the Sonic? recently retubed with some vintage nos and it is a big improvement over the Linn Kolecktor I had previously.
As to a single amp... I am going to test drive an Aragon my friend wants me to hear in my system.
That Sumiko Blackbird is available with a trade-in on the Blue point at the record Doctor

Blueskiespbd, I know the Moon LP3. I think it is terrific value and would sound even better with a battery PS. So I wouldn't consider changing that at this point if your very nice system were mine.

I do know that a preamp makes a huge difference in a system and I know other SF gear. I think that you would be pleased with the difference if you tried a preamp worth $1200 more than the SF in your system. (Actually a Klyne SK-5A like mine would probably cost about the same as the SF.) I do believe that the SF, especially retubed, is a big improvement over the Linn Kolektor.

I'm hoping you'll post your impressions of the Aragon.

That Klyne sounds like a fine machine especially the phono section. How is it different from the Sonic?

Oh dear, now I think I've intrigued you. Well, no harm done I hope. The Klyne is solid-state, to start with. Which of course means nothing, it's not the technology but the implementation that counts. It is discontinued, like the SF, but went that way much longer ago, back in the eighties. It has a MM/MC phono stage and a very good one. I think you would find it had higher resolution than the SF, to judge from the other SF gear I know, but I have not made the comparison.

And just to repeat, I don't know all your gear and I am sure you are right to be looking at your amplification at this time. I understood your post to mean, "What else would you guys upgrade, apart from what I'm already thinking?" and I hope I haven't driven you too far afield. Funny thing though, Kal Rubinson compared the SF2 with a Klyne 6.3 back when he reviewed the SF2 for Stereophile.

No decision made so far as to what the next step should be other than reading, researching and listening for good advice.
You know sometimes you just want to replace everything and start fresh.
