I have used Bent TVC's in my system since 2004 and I guess curiosity has got the better of me after so long. I want to live with a top end valve pre for a few months and see if I am missing out on anything. After I started this thread I stumbled across a long thread started by a friend back in Australia who also runs active ADAM's. He has tested quite a few top pres including Octave, Audio Note, Lindemann and quite a few others. Thread is here if interested:

He wants a 5SE after hearing it in his system numerous times,he has found it to be the best of the lot and works wonderfully with the ADAM's. I have found 2 reviews of the 5SE where its measured output impedance is less than spec at 330/450 se/bal so that gets the impedance ration to >20x fwiw. His experience and the conversations we have had since have led me to buying an ARC Ref Anniversary today so I will soon find out for myself.
Either the ARC proves a winner or the Bent continues its reign well into the second decade :)
Cheers,
Simon
