Amp upgrade from Ayre V-5xe

I have been using the Ayre VX 5/20 for the last year.  Moved from a VAC tube amp to the Ayre and love it.  Originally used on Thiel CS2.4 and recently on more efficient Spendor D9s. The clarity and musicality of this amp makes me smile daily.  Using a VAC tube preamp. 

My shortlist when I bought the Ayre VX-R

MXR
Aesthetix Stereo ( now in Sig level )
ARC ReEF150

Thyname there are a lot of good recommendations here.   I learned something with this thread.  I'm going to add the VX-R to my short list.  Soundstage gave it a great review but the reviewer noted that he's heard more impactful bass before.  Also, there doesn't seem to be much feedback on this piece either on 'gon forums or reviews.  It would be great if someone did some comparisons with this unit against similairly priced units, (Hegel H30, Luxman M900u, Pass X-350.8, etc....)

I am very close to pulling the trigger on a Pass Labs X150.8

Same power as my Ayre V-5xe.

Is this really going to be an improvement, or just a lateral move?

Should I just go with Ayre VX-5 Twenty instead?

Thanks

@thyname Only way to know is to bring the Pass 150.8 into your system. You already know how your Ayre sounds (and the Ayre ’Sound’). This will allow you to compare the two. It’s how I’d approach it.
