iven that the ideal amp ifier behavesI ke a p ece of wire with gan, the best you can

that anybody notices. So Davd Berning stads with a disadvantage,which he then compounds by making his products look neat to the pont of blandness,and which weigh barely more than the packagingthey weresh pped n. The ZOTL and Zl'23o pre/power combination,reviewed by CT n lssue 80, is pretty self-effacing.The maker's narne is subty and elegantlymlled into the top panel, where t is likelyto be obscured by your rack, the power amp boasts JUSIan o1,ojl swrtc- a.lo 'non [o' LED and rfe pre amp uses doorknob-shapedcontrolswhich make the facia more interesting,but are not a particuady strong aesthetic statement. t, too has a monitorLED, whch sn't the same colouras the power amps. Actualy, that's one genuinecriticismI have of ths combination.The LEDon the pre amp stans off red and goes to green once it's warmed !p and ready for use, the power amp also requiresa similar warmup time, but its monitorLED staysresolutelyred throughout, f you wait for it to go green,you'll be there for quitea whie...

The warmup is because this is, essentally,a valve amplifier. But t's an interestlngmix of old and rew rech.a si'np,stc analogybei'g swltched-mode somethinglikea valve-modulated power supply.No output transformers(hencethe 'OTL in ZOTL)whjchhelps create the zero hysteresjsdesign (the '7N' in ZH23O)leadingto the clean, fast, crisp de ivery wh ch seems to be paft of the David Berning signature. Interestingly, the amps will become significanty more relaxedafter about 20 minutesof use - and that meansputtinga musicsignalthroughthem, not merelyleavingthem switchedon. Asidefrom the modest power output - ihe 7H23O ls a 3o-Watt per channel stereo chassis- it's difficultto powint to any particularlyvalve-likecharacterstics n the sound. Ths is a valveamp for peoplewho thinktheydon't likevalveamps. And that 3o-Watt output is m sleading,too.

Don't mlstakethis for meekness,the amp is far from shy, lleing more than capableof grabbing,and holding,your attention.Take,for exampe, SteveReich'sS/XPlaros, a work of endlesssubtlely,or never-ending tedium,dependingon your point of view This is a piecein whichthe dynamics bareiyvary thereis no melodyto speakof, just an ever-changing and complex interplaybeh/'/eenthe six pianos,chantingphraseswhich morph subtly nto new phrases,almost without the listenerbeing aware.Throughthe Berning amps, but padicularlythanksto the pre arnp,the structureand shape of th s most amorphousof pieces is revealed.Now it's a fascinatingand hypnotc journey,which eaves you breathlessat its precipitousending, rather than watng for it to be over; it becornescapable of transportingihe istenerto anotherolace entirelv. And it was the same story with pretty much any type of music I played. Regardlessof the son of programrnematerial,the Bernng combinaton s part cu arlyadept at showingyou the musicanship,the way a sk lledperformer introduceslayersof nuanceto a pedon.fancewhich bring t to life;an nflection here, a touch of emphasisthere, al adding up to rathermore than the sum of the pads.

Lo QueMe Hace Vivir,from 'Akokan'startswith a gentleand liquidphraseof such prettlness and delicacy,then explodesinto a rollicking, headlongdash. To havethe one, without the other,would be to missa greatdea. Nothing I've used before,or slnce,the Bernng ZOTL and 2H230 has reachedthe levelsof lns ght achieved by this unassumingpair. lt's not just about filigreedetail, or speed, nor s it merelyabout texture or tonal accuracy, the Berning combination s simply so nimble, t sn't fazed by whatever you ask of it. lt's about a product which, to a degree I haven't previouslyexperenced, acts simpy as a conduitfor the music.
