| High end stereo preamps? Worth it? In a blind test no preamp can improve upon no preamp. That one needs to be etched in stone, as another great audio saying.Just like "it all starts at the source, get that right and your almost there" (Ivor Tiefenbrun Linn Sondek)Cheers George | |
| High end stereo preamps? Worth it? There isn't a preamp that's built into a dac that's even close to a good high-end preamp. That's because they're far more transparent and dynamic, because there is no preamp, and all the volume controlling is done in the digital domain, just ha... | |
| Budget Tube Preamp ($2000) saltboy you must be living under a rock.Ya canna go past the Schiit Freya, even if it were $2K!! and it won’t cost that much!! And it’s 3 preamps in one to suit you moods, also has the best mechanical volume control you can get, all remote contr... | |
| Benefit of shielded ac wire? Any downside? In Australia 240vac I believe it can’t be approved because it’s considered illegal and dangerous, and you wouldn’t be covered by insurance house or personal should the mains short to the shield, which would be attached to the case of your equipmen... | |
| Classe 25A amplifier highend64 OP The Classe DR25 was a nice amp, very powerfull, smooth but laid back (dark) sounding, not the last word in detail.Don’t use it’s balanced inputs as they were just an opamp feeding a single ended input of the amp, you got better sound ... | |
| Amp repair cost — is this right? In Australia a "reputable repair shop" charges $115-$130aud per hr that $80-$90usd. Like I said it would take a tech that "cares" about a day to do this properly heat soaked and biased back up. And then there’s the "quality" parts 16 x large power... | |
| Amp repair cost — is this right? Mine is just an amp, and the internal layout looks completely different Just as bad as all the output transistors are attached to the side heatsinks, and all are bolted https://lh3.googleusercontent.com/proxy/0iU9BZNQ1_1LRwvGt1SJX9PgT8TkYLok8IVLM... | |
| bridging an amp He's going to go backward in sound quality if he bridges if he has a decent system, just for the sake of going louder.Cheers George | |
| Amp repair cost — is this right? jnehma1 OP To dismantle (unsolder those transformers and the chokes he used) and anything else, pull the boards out of this, and do all the electrolytic caps on them, as well as the power supply caps. And then to bench test, measure everything, wa... | |
| Which phonostage should I choose (or would you choose)? aj523 OP Which phonostage should I choose I’m always for all battery in sources when it can be properly.https://www.stereophile.com/content/channel-d-pure-vinyl-5-seta-l-phono-preamplifierCheers George | |
| bridging an amp Tell him if he wants more watts, to sell them, and get the correct amps with the wattage he wants in a normal stereo amp/s. And to forget about bridging!Cheers George | |
| bridging an amp g_nakamoto what are the pros and cons of bridging an amplifier? Bridging amp raises the wattage quite a bit, but that’s where the advantages end.1: Distortion goes up,2: Output impedance is higher (damping factor lower), which means bass is not ... | |
| Passive preamp issues or? If the amp really has a 1MegOhm input impedance Oh dear! This is getting like a Monty Python skit.He doesn’t have an amp with 1megohm input impedance, I’m just saying that the Rogue M120 the only amp I know of that would be an "impedance match" w... | |
| Your most indispensable "tweak"? redwoodaudio Your most indispensable "tweak"? My 6mtly visit to my ENT Professor to vacuum the old wax out of the ears, after it you swear you come out hearing like a bat.Scroll down and watch video, and you'll see what I mean.https://www.in... | |
| Passive preamp issues or? There it is! The problem is either the high output impedance of the Jolida at 47kohm (which is wrong for anything mind you) save the input impedance of Rogue M120 monoblocks, which are for memory 1megohm, or similar, they would give a good ratio o... |
