Larevoj,that's comparison is basically what I heard when I auditioned my 26 with the Ref 5 about a year ago.
I definitely could live when them both which I kept my 26(couldn't afford the 5 then).
I did pick up a Vac pre which I like very much,still have the 26.
Now that I have both SS+tubes I have a few more flavors,besides if either need a repair I have backup.
Been pondering the SP-3 as I have heard the pre in there is really good,perhaps the 26 might go up for sale and I'll
still have a superb SS pre+AVP

,(we'll see

).
