Amplification for Shahinian Obelisks?

Hello there!

I just had my newly-bought second-hand Obelisks overhauled at Shahinian, and now they are on my way to me.

At this stage I am thinking of amplification for them.

I listen mostly to acoustical musiс (Norah Jones, Madeleine Peyroux, and the like), jazz of all sorts, mostly modern ECM-style, also some older Blue Note, and pop music (a lot less). Almost no rock, although it is gaining on me (in the car, though).

I have had several Macs (integrteds and separates), loved their sound, but I want to move forward: Macs' sound is a bit too relaxed for me (although I don't like the sound to be overly crisp). The most important thing for me is musicality and space: I like to listen to music, not sounds.

I want as few boxes as possible, so I want a DAC with an amp in one box. It will be fed through coax or optical from an upgraded 24/96 Sonos.

The contestants at this stage are

1. Electrocompaniet ECI 6 DS
2. Hegel H300
3. Plinius Inspire 980
4. Devialet 120

I am currently leaning towards the Electrocompaniet or Hegel.
Would appreciate your comments on these. Or, maybe, I am missing something here, and there are more choices?

I dont have an opportunity to audition them in my home town, unfortunately, so it will be more or less a blind buy.

Comments from Shahinian owners are more than welcome.

Thanks a lot for your comments!

Johnnyb53,

Thanks for your input. However, I have always had a problem with the words "low" and "high",not being an electronics engineer or something...

So, you got me guessing: when saying "low" or "high" what do you mean exactly? Above or below what figure?

Thanks!

Don't rule out good Class D. You may be delighted in every way and even save some money in the end (on both amp and subsequnt power bills) if Shahinians's are anything like OHM Walsh speakers. I use only Class D with those these days and cannot see ever going in a different direction. I've been pleased as punch with both Bel Canto Class D amps I am using currently in my two systems (C5i integrated and ref1000m monoblocks).

That's true, Mapman. The best traits of good Class D are a lot like high-current, low output impedance A/B amps--speed, fast and copious current delivery, stability into fluctuating loads, and high damping factor.

I have had a pair of Mirage M5si's in daily use for 19 years. They and their larger brothers (M3si and M1si) thrive on amps of these sorts, and one HFC-er particularly mentioned that his M1si's really sang with some Class D amps.

Rowland is another major Class D maker. For a more economical approach, some Red Dragon monoblocks or the S500 Stereo amp might be an easy way to bring life to these Shahinians if Red Dragon ships to Russia.

I agree with Mapman...I am experiencing wonderful synergy with my Class D Audio 470C (300 W/ 8 ohms) and my Ohm 2/2000s, which are current-hungry beasts as well. The question is can you find an all-in-one integrated with DAC that has the power to drive the Obelisks (not sure 60W does it) that is not only class D, but also available in Russia....I used a W4S mINT (at 125 W) and it wasn't quite up for the task, IMO. YMMV, however.
