I think your wish* is almost universal. (* Having SS stuff that sounds as 'good' as tubes and doesn't require maintenance.) But if you've become fully appreciative of the value of tube sound you may never acclimate to SS and regret your decision to move back to SS. And, if Murphy's law is still in force you will discover that SS requires maintenance, and you will want to change the tone, etc slightly and not be able to make the adjustment.
I don't know what your ARC system is but if you are using seperates you might consider scaling back on the amp by buying tubes and biasing them in your self (it sounds like you are having the work done by ARC. Ditto on the pre amp. An amp with a quad of power tubes only costs $150 to $200 when you do it yourself.There is a small learning curve attached, but its fairly shallow.
