I like this idea, class A with 23 Watts into 8 ohms. Should be more than good with Susvara.

It's a sweet sounding amp, not the last word in detail, but consistent and calm from top to bottom. Something like the Pass INT-25 wipes the floor with it, but is also tres' expensive.

Both class A but different. Interesting, isn't it :) ?

I do find differences between Class A and other classes but within Class A we have sliding bias - Threshold & Pass, we have many tube amps, full bias SS, FET's, JFET's. I've been all all Class A since the early 80's - Electrocompaniet 25/25, Threshold Statsis 3, Krell KSA-50, Krell KSA-100, VTL Deluxe 140 w/ 807's, Jadis, Pass Aleph 3, Pass Aleph 5, Pass X-150 (2), Pass X-150.5, Schitt Ragnarok 1, BHC w/ speedball.

The Pass Alephs, X-150's, and Krell's were pretty similar to each other, the others were all over the map. I think Nelson Pass is the best amp designer of the past 50 years.

I wrote the above because many folks associate class A with certain sonics, but in reality it's as you've just said: there's a sliding bias within it that leads to at times very different results. And yes, Nelson Pass is one of the greatest if not the greatest audio engineer into transistor amps :).

Pass has used lots of tube circuit ideas in some of his designs on the SS side. I've heard well over half of his amps, and they are just amazing. I sold off my 150.5 about 3 years ago and I do miss it.

Ah, yes, Nelson Pass SIT amps were designed to mimic tubes weren't they? Transistors he used in these products have tubey characteristics, don't they?

If I may ask, why did you let go that 150.5? Did you see .8 as its upgrade?

No, sadly we decided to sell our home which included a listening room designed and partially built by me. I had a pair of 150.0's which I used on big speakers (ML CLS IIz and Verity Parsifals). I got the .5 when I settled with the Parsifals - IMO the best real world speaker I ever heard.

We now have a home less than 1/2 the size and listening room is so awful (ProAc Tablette sound fair = at 80 db. My Triangle Celius 202's collect dust. So I bailed inot headphones. I didn't know about HFM HF-6's or I would have kept the 105.5. 105.5 is closer to the .8 then the .0, so I wasn't tempted. I'm going to build one of Pass's kits - just to have it around, and given the past, I might use it a lot.

Thanks for explanation and apologies for asking this much. And Verity Parsifals, wow. I've listened to them in Munich (with Reimyo if I recall correctly) and they sounded "good" enough so even today I remember their sound. As for HE-6 and Susvaras, yes, the 150.5 would probably do very nicely with them.

Chord Hugo 2 would be a strong DAC contender in the price range - especially if used. For an Amp, I'd consider something like a Cayin iHA-6 to get you started?

Within budget (well within if buying in the US, not so in the UK), high power output (and current) for the Susvara's, solid build and I liked the pairing of the Hugo 2 and the IHA-6 (subjective of course).
