De Trafomatic Premise.
De Premise is een verkleinde en betaalde versie van het klankbeeld en karakter van de grotere broer van de Premise de SM-300b. De Premise is op basis van de zeer muzikale el84 buis doet alles wat zijn grote broer ook doet, uiteraard gaat de sm-300b verder in het nog fraaier neerzetten van het midden gebiedt, echter u zult meer dan positief verbaast zijn hoever deze minisuper versterker mee kan komen.
Vanuit een review:
Here is what our own John Darko had to say about the Premise:
“With his Kaivalya monos receiving raves across the board, Sasa Cokic distilled their essence into a gloss-white-lacquered push-pull integrated. The Premise twirls with EL84 tubes; this means super-fast, super clean reproduction without the butterfat that can burden lesser EL34 designs. Musical layering is another standount. Cleverly, Cokic has designed the Premise so that it can be used as a power amplifier and triode/ultra-linear modes are top-plate switchable to suit mood and musical flavour. The former brings a shade more romance, but the delta is sufficiently subtle that you won’t spend all day yo-yo-ing between the two. A glorious and grandiose amplifier that once again proves that bang-for-buck can still be found at the high-end. Don’t be misled: this might look like show-pony hi-fi but the Premise offers performance that you’d be extremely hard-pushed to find for less money. You can show it off to your audiophile mates, it sounds sublime and your partner will be less likely to object to it as a lounge-room centerpiece. A modern classic.”
Had to argue with JD. Don’t underestimate it, this is a high end amp that delivers high end performance. The Premise certainly does pull you into the music. This particular amp is in gloss black rather than the gloss white- just my personal preference.
After releasing our Kaivalya monaural amplifiers, we were asked for an integrated stereo version with remote control. Retaining the Kaivalya’s class A p/p output stage around a quartet of EL84/6BQ5 per channel driven from an ECC81, the Premise merely omits the complex and costly interstage transformer of the monos. With three inputs and 20 watts of minimum feedback tube power, the Premise not only inherits the white lacquer finish of the Kaivalya but the lion’s share of its sonics.
