| Step down transformers detrimental to SQ? I heard some crazy Japanese audiophiles do double conversion, up and down, and claim it improves the sound. Not quite but close, there is a bit of a fad at the moment over there, to use 1:1 isolation transformers, which are 100v in 100v out they ... | |
| Merrill Audio ELEMENT 118 on Tour merrillaudio OP 300 watts into 8 ohms, 600 watts into 4 ohms and 1,200 watts into 2 ohms Very impressive, to good to be true?? Even "close to it" is impressive.Hi, just to clear thing up, this is almost "perpetual motion stuff", as there are alw... | |
| Step down transformers detrimental to SQ? Step down transformers detrimental to SQ? Just make sure the amperage rating is at least two times higher than the mains fuse on the amp this should keep the core from saturating even a little. Also step down transformers can actually be better f... | |
| Krell KSA 250 amps well they have gotten MUCH better sounding over the years. Sorry I don’t agree, the ones with static set Class-A bias "if in good operating condition, to me sounded better than the ones with auto Plateau (sliding) biasing. The very best highest C... | |
| Krell KSA 250 amps Does anyone have info on what to ask for 2 non functioning amps. In non working condition, they "could" be a simple fix or a "very" expensive massive fix, both by experienced technicians that have the service manual. So they are worth a gamble at... | |
| Do you find battery supplies inferior to well designed power supplies? paul79 Do you find battery supplies inferior to well designed power supplies?I have to ask, because every single battery powered unit or battery supply I have ever tried sounded great for the first few tracks, then focus gets blurry and things... | |
| A DAC that can make digital sound analog? brettmcee A DAC that can make digital sound analog? This was an interesting shootout, and the winner, also the most analogue and smooth sounding. Was the oldest one, a Theta DS Pro an old PCM63 R2R based dac.https://www.superbestaudiofriends... | |
| Tube amplifier suggestion for 101 dB speakers piramis OP The speakers are highly efficient here with 101 dB, but also they are 4 Ω in impedance Yes as I said before, and that’s a nominal 4ohm, it will have dips even lower than that.Look for an amp that has a 2ohm speaker tap just in case ... | |
| How to DIY yourself very nice Class D monoblocks I’d be more inclined to have a go at these, USA made sold and backed.https://classdaudio.com/amplifier-kits.htmlProper linear power supplies with Toroidal transformers, not noisy switch mode ones.And these are far less costly than the Euro alterna... | |
| Does my amp have enough juice to power my speakers? Sorry in my last post, the link I posted could be the wrong one, and this could be the right one of the impedance/phase angle curve of the Audio Physic Step, much harder to drive. https://www.stereophile.com/images/96APS-fig1.jpgCheers George | |
| Which Class D Amplifier? PS Audio, Ghent, Nord, Merrill or other??? Speaking of directional mains fuses AND THERE IT IS!!! and the bait was very old and smelly.Right on cue, mention one word about SR’s directional AC mains fuses, or HFT’s and the snake oilers sniff it out. | |
| Which Class D Amplifier? PS Audio, Ghent, Nord, Merrill or other??? What if they are not? Like their directional ac mains fuse, there is only one answer to that. | |
| Seeking info N.E.W. Nirvana Electronic Works A20 calclassa The A 20 was designed by Nelson who always wanted to design a small Class A amp. BTW: Nelson Pass did design a A20 in 1977 but I don’t believe he had anything whatsoever to do with the N.E.W. A20 or A20.1 it could just be a ripoff clon... | |
| Which Class D Amplifier? PS Audio, Ghent, Nord, Merrill or other??? Im about now to try the Synergistic Research HFT (10 Pieces). You had me reading up till then, lucky it was your last sentence and not your first, if it was I would have ignored the rest of your post, I hope directional ac mains fuses aren't next... | |
| What class of amplifier has the most high definition sound ? Class D amps take some meat off of the bone. It can come off as crystal clear, defined, and completely quiet between notes (inky black) but to my ears that sound signature is the result of removing a tiny amount of the music from the source. My g... |
