ne interesuje mene 2nd harmonik... i ovako ga previse imam na SS i ono sto ce bude... cist 3 hocu. Secer na secer ne ide. Visem volim neutralnost

ja sam to hteo drugacije @vladd, malo prakticnije i iskustvo. Grip me oborio ovih dana, ja sam trenutno off... do poste pa u krevet

nisam se uvredio, samo sirim prakticne stvari, iskustva drugih. Misljenje sam da na istim snagama ova topologija se drugacije cuje sa drugacijom voltazom.

nema ovde nikakva mistifikacija, pricamo o prakticnim stvarima ljudi kako su radili i sta su dobili. Zar je to toliki problem. nevermind, svako neka radi kako zna ume enough for me

znaci, na istim snagama, dva ampa sa istom topologijom, razlicitom voltazom, se drugacije cuje? Ne manjka ni jednom ni drugom snaga...

da, problem sa tim JBL zvucnicima koji su laki za ganjanje, nije se culo isto, brte @Aleks

@Aleks ajmo dalje... isti forum. https://www.homecinema-fr.com/forum/diy-amplification/up-grade-t30013308-15.html?hilit=2n5461 Par rapport au premier UP, je pense que la différence se trouve plus dans sa facilité à jouer des attaques complexes, un peu plus de rapidité / tenue des graves. Ça remplit bien la pièce, ça donne encore plus envie de taper du pied. u prevodu: Compared to the first UP, I think the difference is more in its ease to play complex attacks, a little more speed / holding bass. It fills the room well, it gives even more desire to stomp. Jesi li se nekad zapitao , kako se .5 u Srbiju cuo, jedan sa jednim naponom, drugi sa drugim naponom?

ljudi ovde nisu uporedjivali 800D sa velikim stanom nego 2 UP susy sa 23vdc i jedan sa 32VDC. Mislis da zbog velicine jedan slusali jace a drugi slabije? O Boze... nevermind...

ne pali me. 2 ampa su mi na stolu da nahranim Scan speak... na kraju ce me naterate da pravim Tannoy

bice to odlicno, kad Zen zavrsi. Ne sumnjam.

Miko, sve je meni to jasno i sve ok.. samo mi jokey nisu jasni... da li sve vreme drze sluske na usi

ono, zasto sam se opredelio za UP-grade verziju na 32VDC tj 24VAC, @Aleks da vidi, da ne kaze da je samo snaga u pitanju, vec ima malo i nesto drugo. https://www.homecinema-fr.com/forum/diy-amplification/up-grade-t30013308-135.html?hilit=2n5461 Bonjour à tous, hier mon upgrade est allé faire un tour chez Oo7livier qui n'habite pas très loin de chez moi pour évaluer l'UPgrade face à 2 Youpis standards (en façade malza superbes au passage). un autre forumeur Ged23 était présent lui aussi. l'écoute s'est faite sur des B&W 800D dans une salle assez grande. je vais laisser à Olivier le soin de faire un compte rendu de son ressenti, mais le verdict a été sans appel. l'UPgrade à gagné par KO. non seulement le grave est mieux tenu mais le medium et l'aigu bénéficient des améliorations. au niveau médium les instruments prennent plus de corps (mélodie Gardot , I am a fool, la résonance de caisse de la guitare (30s à droite) prend du volume et de la matière. l'aigu est niveau globalement plus doux/plus fin. l'image est aussi de mon point de vu plus précise et les instruments plus détourés. en gros le ressenti que j'avais eu sur mes panneaux s'est retrouvé sur son système. u prevodu... Hello everyone, yesterday my upgrade went to take a walk at Oo7livier who does not live very far from my home to evaluate the UPgrade against 2 standard Youpis (malza facade superb in passing). another forumer Ged23 was present too. listening was done on B & W 800D in a room big enough. I am going to let Olivier report on his feelings, but the verdict was final. the UPgrade won by knockout. not only the bass is better held but the medium and high benefit from improvements. on the medium level the instruments take more body (Gardot melody, I am a fool, the resonance of the guitar case (30s on the right) takes volume and material, the treble is globally softer / finer level. the image is also from my point of view more precise and the instruments more out of the way ... basically the feeling I had on my panels ended up on his system.

jok, nemam... imam samo za ugs preamp... Moracu malo da se pomucim ako ne dobijem konkretne savete. ono sto oni kazu sa njihovog foruma. And the gain in all this? Ben as it is, it is about 23dB. But it can be modified easily by changing some resistances (ROUT, RFB and RIN these last two being the resistances of the reaction), and according to the simus one has: RFB = 392K / RIN = 27K / ROUT = 1K -> 22.1dB RFB = 392K / RIN = 27K / ROUT = 10K -> 23.1dB RFB = 392K / RIN = 22K / ROUT = 1K -> 23.7dB RFB = 392K / RIN = 22K / ROUT = 10K -> 24.8dB RFB = 499K / RIN = 27K / ROUT = 1K -> 23.9dB RFB = 499K / RIN = 27K / ROUT = 10K -> 25.1dB RFB = 499K / RIN = 22K / ROUT = 1K -> 25.5dB RFB = 499K / RIN = 22K / ROUT = 10K -> 26.9dB So you can adapt it as you want. The choice between a 10K or 1K Rout (or any other intermediate value) will be done by ear, the repercussions being subtle and highly subjective. Another possibility that is offered is to be able to choose between a local or global feedback by closing the loop at the output of the first stage (CR "local") or on the whole of the amp (global CR). Again, the choice is by ear, but to summarize, the local CR sounds a bit warmer than the global CR, offering a more in line with the Alephs X. But it is mainly a matter of taste perso: P. Note however that the local CR slightly decreases the gain, since the "gain" output mosfets (mounted followers, and therefore gain <1) is no longer offset by the loop of CR. The first stage is powered at a voltage slightly higher than that of the power stage, just to make the most of possible voltage excursions, which naturally brings us to the ... E sad, sve ostaje na uvo da se cuje...

aj prebacite zadnja pisanija iz kablova... ono sto mene interesuje, opcije koje mi se nude su: RFB=392K/RIN=27K/ROUT=1K -> 22.1dB RFB=392K/RIN=27K/ROUT=10K -> 23.1dB RFB=392K/RIN=22K/ROUT=1K -> 23.7dB RFB=392K/RIN=22K/ROUT=10K -> 24.8dB RFB=499K/RIN=27K/ROUT=1K -> 23.9dB RFB=499K/RIN=27K/ROUT=10K -> 25.1dB RFB=499K/RIN=22K/ROUT=1K -> 25.5dB RFB=499K/RIN=22K/ROUT=10K -> 26.9dB Da ne jurim simulatore, mozda neka iskustva sa FB... da li bi promena njegova uticala na THD spektar.

ako posmatramo diferencijalne pojacivace, gledam ove francuze. Da li sa promenom feedbacka, osim promena gain-a moze da se utice i na THD spektar? Kakva su iskustva u tome?

point 5 je takav, cist, koliko znam sa point 8 je Papa uspeo u svemu tome, da dobije 2nd harmonik.

kazu kad imas XLR vezu, da bilo koji kabli stavis na RCA ne mozes da dobijes to sto daju XLR... hm.

dobro da nemas gain clone

nemoj samo kao disc jokey da na velikom forumu kukas kod pape kako se to ne cuje kako si ti ocekivao

opasan album. Nigde ne mogu da nadjem da skinem flac...

hahaha

dajte bre, sta ste se popalili toliko. Pa Mika ce da radi isto kao i sa kutije kada menjeo induktivitete, stim sto ce sad da menja one, zlatno, srebrno, niklovane trafoe

pa kako to sad nije lampa, bas ste onakvi... lako je na vas sa ti Tannoy da se ... sa malu snagu.
