Winner of The Absolute Sound's Editors' Choice Award, the S-300i employs a Class-A, fully balanced Krell Current Mode Preamplifier section.
I have used this amplifier to drive my Martin Logan Montis electrostatic speakers and my Sonus Fabers and it is easily the best amp I've used with both of those, very different, speakers. Sadly with kids and life I rarely get to enjoy my music and so this amp has hardly been used for some years. Have now sold the Martin Logans as I downsize and move to a more modest system.
It is a used amplifier but in excellent cosmetic and operating condition. It comes complete with the very sturdy remote control. I do not have the original boxes however I can pack this amplifier very carefully for shipping if required for an interstate buyer.
Dimensions: 43cm (w) x 43 cm (d) x 9cm (h)
I'm looking for some advice for a good budget stereo amp and floorstanding speakers combination?
I'm definitely want used equipment but that means I wont necessarily be able to try them in combination before I buy.
Budget is ~2500
Room: 3.5m x 7m, wooden floors.
Music: Classic rock, Metal, Reggae, Electronic.
Source: Spotify (probably using Chromecast audio, unless someone recommends an amp with Spotify Connect?)
Any advice or experience people have would be greatly appreciated!
Item: Schiit Ragnarok - integrated amplifier (60wpc into 8ohms + 100wpc into 4ohms)
Location: Inner West, Sydney
Item Condition: Very Good (9/10)
Reason for selling: Upgrade - moved to a pre/power combo (can't really justify the Rag as my 2nd amp in the office, much though I'd like to!)
Payment Method: Pickup - Cash, Paypal (+fee), EFT
For sale is my Ragnarok by Schiit Audio of the USA. It is in great condition. Comes with original boxes (x2).
I am its second owner. Moved to a pre/power combo (as you do), and need to make way.
It is smart and very capable integrated. A terrific headphone amp. I think best with bookshelf and small/efficient floorstanders. It sings beautifully with my Wharfedale Diamond 220s, but not quite enough heft (for my ears) for my Krix Neuphonix Mk I.
Of the Ragnarok, it has been said:
"...it's the first amplifier of my experience that plays earth and sky, mind and body, brown eyes and blue, speakers and headphones, with equal narcotic intensity. It likes every type of music. It's fully balanced. It's frolicsome. The Raggy is made in California by two exceedingly Ras dudes... Like the classic NAD 3020 of the 1970s, the Ragnarok signals the beginning of a new Renaissance in high end audio. It is the perfect introduction to the joys of quality music reproduction in the home."

For my listening tests I first hooked up Ragnarok to my Magnepan .7 flat panel speakers, precisely because they are far and away the best speakers I've heard for the money, but they're a brutal load for amplifiers, and most AV receivers and budget integrated amps never come close to making the .7 speakers sing. The Ragnarok fully exploited these speakers potential... Paired with my KEF LS50 bookshelf speakers again the Ragnarok kicked butt, the speakers really came alive with this amp, dynamics and bass slam were hugely impressive for a small speaker. Stereo soundstaging opened wide, there was a nice dimensionality to the sound with great recordings, like the soundtrack album for the film "Birth." I also had great results with my Zu Druid V speakers, and it's with those speakers I totally rocked out with the Ragnarok. Bass punch, truly visceral dynamics, combined with a sweet midrange tonality were the fruits of this amp/speaker combo."
