Solid State to replace Audio Research REF110?

Charles1dad, My only point is not all talented designers agree on the same principles. Obviously some talented designers do find fuses degrade performance.

Customers can choose whatever they want. In your example, your friend prefers VAC so he buys VAC. Some prefers ARC, they buy ARC.

Hi knghifi,
Yes, my point as well . We don't disagree. I was actually hoping a designer/builder would come along and explain the rationale for either circuit protection option for handling a blown output tube.
Charles,

Hi,
I also replaced my Ref 3 pre with a Pass Labs XP-20 and am pleased with the results.
If you can find a SS design that sounds as good as tubes, why use tubes?
Of course, the debate will be IF!

Mikewerner,

If I follows well you have a Pass Labs X350.5 and a XP-20, and you had also a XA60.5.
How these combos compare with REF3 + REF110 (which I also have)?
I just adquired a XA30.5 and plan to buy a XP-10, it is not the same than yours but I think could sound similar.
What are the differences between XA60.5 and X350.5 in terms of sound quality?

Thanks.

Hi
I had a Ref 3 and Ref 110.
I got tired of replacing tubes. My equipment is on a lot.
The Pass Labs X350.5 has control. It doesn't stress or strain even with large scale orchestral works. This into 87dB speakers.
The XA60.5 was just not holding together on the big stuff when played loudly.
I frequently am not in the room with the speakers when listening.
That said, if you like to listen quietly and are a spacial junkie, some say the XA60.5's do that better, though it didn't seem much of a difference to me.
On the ARC gear, I still think as neutral as some claim it to be, there was still some colorations that I do not find present with the Pass Labs gear.
So, I am happy with the solid state gear sonically and do not have to replace tubes!
Plus, if you have never heard a BIG solid state amp, you should.
Power is not the limiting issue, and that says a lot about the sonics especially at higher volumes.
