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.

@alaindexe,

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. Mike

@alaindexe,

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. Mike

@alaindexe,

I just copied this off the Schiit website Ragnarok 2 amp.

 

Is this a Class A amp? For most headphones, this is technically a Class A amp. It runs about 1W of Class A bias. For speakers, that translates to Class AB operation.

 

@alaindexe,

Hi, Al:

Yes! The JBL 4435’s are amazing speakers, they have great bass and transient response and very low distortion and have a better low midrange then the 4430’s which I previously owned. The 4430 and 4435 are very coherent speakers. When the 4435’s are actively BI-AMPED, they sound even better. I use them for home HI-FI listening, Great imaging and sound stage. I also have a pair of JBL 4425’s that are nice little speakers. FWIW, Valveglow did a nice review on the 4435’s.
