Upgrade for Totem Mani 2

Having had several different Totem speakers, though not Mani 2, I would suggest taking a listen to Dyaudio. Similar to Totem but better to me. Totems I had could get a tad harsh sounding with certain recordings. No issue with my Dyns. Plus your Pass amp will pair very well with Dyns. My current speakers are Dynaudio Contour C20. Knowing the Mani 2 has great lows I don't think you'll miss much of that from the C20. 

A pair of Vandersteen 2's are in the 2500 range if I recall correctly.  The fact that they are time and phase correct will stop the smearing that you will get with a non time and phase aligned speaker.  It's very noticeable on acoustic music and also jazz.  Having a full range speaker like the 2's are also nice for the lower bass notes I have found.  Dynaudio makes a nice speaker also.  I auditioned many of them when I was looking and my buddy has their 60k ones.  I just feel for many they appreciate the tonality, micro and macro dynamics of the Vandersteen's.  Go listen to both and see which one you like best.  They are very differently tuned, so I'm sure you will like one or the other better.  Both good solid companies that stand behind their gear too.

You should check out Harbeth. The M30’s go for about $3500 used and the 7’s about $2500 used. They both would be a nice match with the Pass amp. They are an easy load and sound great with the type of music that you prefer!
