Just to be clear: All class AB solid state amplifiers run in class A to a point. Case in point the Schiit Ragnarok 2 runs class A for one watt and class B for 59 watts @ 8 Ohm. In my system the Ragnarok 2 amp generates less heat then my 20 watt class A mono block amps. Also,500 watts maximum power consumption from the wall socket is when the Ragnarok 2 is running @ maximum output power 60 watts @ 8 Ohms and 100 watts @ 4 Ohms. But when the Ragnarok 2 is outputting 3 or 4 watts into your speakers that power consumption from the wall socket I think will be very very low. FWIW, The Ragnarok 2 sounds great in my rig. My speakers efficiency is 2.7% @ 8 Ohms. My room is 13'x25'x 9'. The only way you will know how it sounds is to try it in your system. If you do not like it return it back to Schiit. Hope that helps.

A decent integrated amp under 2K ...
I'm looking for an INTEGRATED AMP. My speakers are Altec 620A (100 db efficiency) and my listening room is 14 x 21. I mainly listen to digital files from my DAC (Metrum) but sometimes I feel less lazy and put on a vinyl on my Garrard. I don't need a phono stage, I use the one from another integrated amplifier (Spendor D40). Here's my shortlist:
1) Belles Aria Integrated (slightly powerful for my needs)
2) Croft phono integrated (since I don't need a phono stage, I think it's a shame to burn tubes for nothing)
3) Rogue Sphinx V3 (too powerful for my needs)
FURTHER CONSIDERATIONS: I can live with tubes but only in the PREAMP section and I try to avoid Class A due to the heat. I'm open to Class D (proof: the Rogue) but the choice is limited and these devices come with a bunch of stuff I don't need. I rather spend my $ where it will make a difference.
regards

@ditusa : I know about this class A/B thing ... I was talking about the class A section of the headphone which is - according to Schitt - 6 watts ... this doesn't seem much, but still I'm wary of the heat generated by class A ... BTW, it's not convincing to say that it heats up less than a 20 watts amp in class A since everyone knows that such an amp emits a LOT of heat ... I read the 52-pages pdf file with all the graphs and detailed specs but NOWHERE does Schitt mention standby consumption, idle consumption or give any other consumption figure, which seems suspicious for a company generating so many measurements for its devices ... You're right about one thing : the only way to know is to try it, but the problem is that I live in Canada and won't be able to take advantage of their trial offer because of the customs ... Finally, you wrote :
I've been in this hobby for over 40 years and never saw such a measure... efficiency is always measured in decibels (db), usually with 1 watt at 1 meter (with a pink noise) ... regards... AL |
Sorry for the confusion: Ok, Efficiency and sensitivity are not the same. My speakers are JBL 4435 monitors and have a sensitivity of 96 dB SPL @ 1 watt @ 1 meter @ 8 Ohm their efficiency is 2.7%. See the JBL manual below specifications last page. As for idle current consumption for Schiit Ragnarok 2 I don't know what that figure is my guess maybe 75 watts quiescent. As for the difference between sensitivity and efficiency see the link below JBL technical note first page sec;c. Hope that helps.

@ditusa : Wow! these are amazing speakers you have ... a friend who has a recording studio has 4430 and they are awesome ... never heard the 4435 but I guess the extra 15 inch gives it better response in the bass ... Do you use them for monitoring or hi-fi listening? It seems that I learned something new today ... I always thought that efficiency was expressed in db but now I see that sensitivity and efficiency are different ... sorry for the mistake .. AL |
