Thinking Hybrid Integrated.

+ for Modwright.  No experience with Dan’s amps but he tube modded my OPPO Sonica DAC years ago. Does great work.  Stand up guy. 

A counterpoint to my friend @astolfor based on my experience with the Pathos Heritage InPol Integrated.   My shipped unit also has a non-functioning VU meter.  A mechanical glitch which did not affect sound output.  My experience was that my dealer Upscale Audio, Pathos US tech and Pathos in Italy were all over the problem.  They replaced my unit (from Upscale’s inventory) as soon as the problem was verified.  At $17K we’d hope to avoid such issues.  However, IMHO the true measure of a company is how it resolves product complaint issues.

I’m a Pathos fanboy.  Incredible with Tannoy Kensington GRs.  
 

My Heritage is in Italy now for the MKII upgrade.  This is Pathos to me on the mod:

“The InPoL2 MkII and the InPoL Legacy have an improved circuitry, so we introduced it in the Heritage as well; we replaced also some components with higher quality ones. The power remains the same and so the aesthetic design, but the performances have improved with a better dynamic. 
The unit will be longer than the old one, it will be provided with new VU meters and WBT speaker terminals.”

As to @astolfor’s comment re VU meter issues, I too had mine repaired. Apparently Pathos recognized the problem as the MKII will have different VU meters.  As to sound, I have gone from BHK 300’s and D’Agostino Progressive integrated and cannot imagine going back to either or SS in general.  However during that time I also transitioned from Focal Kanta IIIs and Rockport Atria ii’s to Tannoy Kensington GRs. As my preferences have clearly evolved toward a very different sound, I am perfectly content to stay with the Pathos/Tannoy and look forward to the MKII.

Sorry. Thought I’d answered your Heritage tube question before.  Replaced the Tung-sol EXC803S with NOS MULLARD mc1.  $$ and hard to find. More stability to the sound. More solid bass.
