Amplifier for Harbeth 40.2

Hi...update time I added a pair of REL S5/SHO subwoofers and now have all the bottom grip I wanted...........the REL are conservatively set at a low crossover so no midrange overlap....

I am quite happy however I have been offered a ten day trial on pass x260.8 separates and am toying with the idea.....

the advantage of the monoblocks is far more class A power 34W versus 15W and so a bit fuller and warmer sounding which might be the icing on the cake for me......

anybody think I should not bother to try it?

I think the Pass 260.8 will be overkill, especially when running dual subs.  If looking for more class A power, go with Pass XA series amp... the XA 60.5 (or 60.8) should be adequate for 40.2's.

I'm using a vintage 125 wpc Music Reference RM9 MK2 tube amp with EL34's with 40.1's and it gives me more than enough power.

@radioheadokplayer @karmapolice Is the Harbeth 40.2 the perfect speaker for Radiohead lovers? I'm a hardcore fan and would love to hear your impression on how Harbeth handles Radiohead with the various amps that you've been trying.

I have 40.1's and have used them with two amps.  First was a Primaluna Dialogue Premium HP integrated.  This amp was magical with them, but upgrade-itus got the best of me and I now run a Lyngdorf TDAI-3170 integrated with them.  The Lyngdorf is the best I have heard.  You should definitely look into this wonderful amp.  I mainly listen to analog through it and it's just awesome.  It's room correction is the difference.  It also has an excellent DAC built in that is pretty great.    
Also, I'm a huge Radiohead fan and have all of their recordings on vinyl.  The Harbeth speakers are an excellent match for their music.  Radiohead have pretty good dynamic range and excellent sonics in their recordings.  Harbeth speakers are meant to present the music as it was recorded, and I will attest to this in my experience.  OKNOTOK on vinyl is one of my reference recordings.  I often play the MQA version of this on Tidal for comparison.  Both sound wonderful.  

Radiohead99,

Harbeth 40.2 needed a lot of amp power and REL subwoofers to truly shine for rock music in my room ....

I found my previous VAC 85 watt tube integrated nailed the ballads and some but not all Radiohead music well....

Depending on your room the subwoofer might not be needed but would recommend at least a powerful solid state amp....
