Amplifier for Harbeth 40.2


I have Harebeth 40.2 speakers and looking for thoughts on amplification for them.

Currently I use the pass labs int-250 and like it but feel could be improved upon.

One recommendation was given by dealer was to go to separates and pass labs 350.8.  That would improve bass further but not sure would improve midrange where previous VAC integrated had advtg over Pass.

Another recommendation was Luxman 900u amp.  This probably gives me midrange improvement but seems less powered than pass pas int 250 and def far less than 350.8.


first all no have experience on 40.2 but have C7 and now M30.1.
Me also Pass lover and own several amp/pre including INT-150.
in my experience move to tube amp bring more plus/magic to the midrange what harbeth famous for !
when switching to SS to tube I can clearly find that SS win in bass control /quality but I’m fans of female singer so that not I’m after or looking for .
also note that harbeth love power so my tube amp have 80w ,never try tube amp below 50w.
hope this help.

I would try both Gryphon and Ypsilon integrateds and would go with tube separates if I insisted on tubes. I believe that no tube integrated would cut it. No, I didn't hear what I suggested to try.
Upgraded to synergistic research Galileo UEF speaker cables and has added more punch and more feeling to music seems like the solution for my system
You might want to add Synergistic or another brand power cord for your Pass.
 My new Mac MC462 works wonders with the 40.2‘s. 
It s the best amp I’ve ever heard with these speakers ( I previously owned the PS audio BHK 250 and the pass labs 250.8 ) and it is best app I have heard. Period
The MC 462 is one of three or four new generation power amps from McIntosh that feature several updates (including increased filter capacity) which  increases  clarity, dynamic range and bass control (among other things) which is very apparent when listening through the 40.2’s.(Check the mcontosh website)
 I think you would be hard-pressed to find anything better for the 40.2s under 20k
You might want to read the RMAF show reports on new Vinnie Rossi amps driving precisely a pair of 40.2's.
Look into the Digital Amplifier Company's (DAC) amp selection. I have had many different class A (Pass, ATC), A/B(too many to mention), and class D amps over the years. DAC's amps have a grain-less sweet clean tone, perfect bass reproduction, and all the power you will need! Plus you get 30 days to try them with a no hassle return policy!
I heard the 40.2 driven by Vinnie Rossi's newest design amps at Axpona 2018. Wow! I also heard the SHL 5+ 40th anniversary speakers driven by the LIO integrated at Axpona 2017. Based on what I heard I bought a pair of the SHL5+. As impressive as the Lio integrated sounded, Mr. Rossi's newest creation is a clear step beyond. He is a true gentleman and very personable. If you are so inclined I'm sure you could call him for more info.
I also heard (twice) the VR/40.2 combo at RMAF. Drop dead. My second favorite room of the weekend (same VR w/Spatial was my fave). If I had $30k to drop on electronics, I would get the VR in a heartbeat.

I have heard the Lio with the 40.2s as well. Much less expensive and sounds great. It is quite low power, however, and I think would limit you to near filed set up.

I would put the Ayre ax-5/20 on your list. Plenty of power, ultra-low noise floor, and very musical. 
I have them with Luxman 900u monos.
I am sure the luxman sound great but preamp mono combo north of 30K to replace integrated costing me 10K is too steep 
Surely the new Luxman L-509X would fit the bill.
I run the Harbeth HL5+ with a Vinnie Rossi LIO DHT, the sound is pretty amazing. 

Air Tight is also a perfect match for Harbeth speakers. 

Any of the Audio Research amps are great. I heard the 40.2 anniversary pair with the top MSB amps and digital. All were run with Audioquest Dragon and Hurricane cords (best I’ve heard and I"ve heard Elrod and Enklein). Just the best I’ve ever heard a pair of Harbeth’s sound in my life. Where do you live?
