New Class D amplifiers


Hello. I'm very interested in getting your opinion on the newer Class D amplifiers.  There has been a couple of very positive reviews (by Guttenberg) of the Bel Canto C6i and NAD M23.  These, and perhaps some others are offering new technology that significantly lower the class D noise level and other drawbacks.    

I currently use a Class A amp, Pass Labs INT-25 (with Dynaudio Heritage Special speakers) which has a wonderful sound. But I am transitioning to another location, and due to using Roon primarily I find that this system stays on most of the day.  Due to heat and power usage of Class A amplifiers, I'm interested in translating to Class D if I find something comparable.

After auditioning Orchard Audio Starkrimson Ultra for 8 days, I had been listening to Line Magnetic 508 and Rogue Cronus Magnum II fitted with vintage tubes.

8 days is too short to reach clear conclusionl without doing cable rolling or comparsion with other refutable class D amp like Atmashphere or Audion.


But Starkrimson clearly has no serious fault at all.

It sounds very transparent with lot of details.

Soundstage is wide and deep enough ( not the best but close to it).



Starkrimson works nice with both Lansche 4.1 and Vaugn Cabernett II.

Thus it is a nice value for sure.

 

I recommend you try it by being in the line for tour.

I do not understand what you are talking about.

In my area the voltage swing around 122 v.

But I had never noticed any problem with Starkrimson Ultra for 8 days.

 

I can not tell which of Atma, Audion, Starkrimson will work better with my speaker yet.

 

But if you are curious about Class D amp, just be in line for tour of Starkrimson.

If there are local dealer of Audion, Atma, I will be happy to do home audition for 2-3 days, but no dealer of them aroung Seattle area.

I pulled the trigger for Starkrimson monoblocks with optional Gan power supply and 3 ft short speaker cables.

The above review by Dick Olsher is informative.

It will be nice if Leo can ship it tomorrow.

By the way one gentleman with Atma D will visit my house with his amp sometime next week

 

Then I will have chance to compare  Starkrimson monoblocks with Atma D.

I use Freya+ with Starkrimson monoblocks.

 

Whenever I use different tubes, it change tones.

I can make it sound fuller or sharper depending on vintage tubes.

Fortunately, I have more than 80 diffferent kinds of 6sn7 and variants.😀
