| Preamp gain vs. poweramp sensitivity @paulfolbrecht Yes, you were thinking about this right. Excellent numeric breakdowns by @herman! Sensitivity in power amps is a voltage input number that has to be referenced against a specific output power level (225 Watts in your case) to reso... | |
| What's A Good Upgrade From A Manley Steelhead? Wish I’d heard a Steelhead - almost bought a used one last year. What do you want to hear from its replacement? More detail & transparency? More warmth and body? More dynamic sound? All of that? (that’s hard to pull off lol). Herron VTPH-2A... | |
| Best turntable under $4000 I have an RT85 and actually like it! Nice sounding deck. I also now have 3 high-end decks: Clearaudio Innovation Compact, Master Innovation, SOTA Nova V. Yes, the high end decks are better. The weaknesses of the RT85: Bad energy management fro... | |
| Stylus gauge recommendations ? I use the Ortofon scale and really like it. I had the Riverstone but it gave me some trouble, I honestly forget what / how, but I chunked it a long time ago 😅 | |
| Concerningly loud pops in vinyl playback Additional notes: Resistive loading made no difference at all. I was overloading the power amp, not the phono or preamp stages 😭 EMI / RFI was not a factor. Rolling out tubes made no difference (and I rolled all of them) - this wasn’t a tube goi... | |
| Concerningly loud pops in vinyl playback Welp I’m now 100% certain this case has a very simple explanation: power amp clipping. The 2 amps I’d been using were very similar in power: 100 Watts/ch tubes and 120 Watts / ch SS. Swapping in the 250 Watts/ch Rogue Apollo Dark, and it sails thr... | |
| Help me choice Audioquest speaker cables Any general suggestions on Silver vs Copper, which cable placements will most likely make a difference as well as if I should replace the AC cables on any of the equipment (of course the Niagara does not come with a power cable. Thats everything... | |
| Retip lyra delos and upgrade An "upgrade" is nebulous because the cartridge was designed as a complex interplay between a very specific set of parts. A ruby/sapphire rod is a lot heavier than boron; I would avoid that for sure. The exact stylus cut is probably far less impact... | |
| Which preamps use 6922/6DJ8 tubes? Exactly @mulveling, excessive gain is to be avoided. Does Art Ferris still make his Audible Illusions Modulus pre-amp (which uses the 6DJ8 tube) with 30dB of gain (!) in the line stage? @bdp24 30dB gain is "holy cow" territory lol. No wonder f... | |
| Which preamps use 6922/6DJ8 tubes? Of all the preamps I’ve had, the ones with 6DJ8 have actually not been prone to microphonics issues. But I’ve had a 6SN7 preamp and another 6H30 pre that were extremely sensitive to it. The biggest trigger I’ve noticed is having too much gain. Onc... | |
| So Weird- No Stylus Contact Woofer Pumping with Hana ML and Elac PPA-2 @mitchellcp Your problem is definitely one of the most baffling I’ve ever read about! Wow. I’m struggling with a different but also baffling problem in my 2nd system - exceedingly loud occasional POP noises during playback - and it’s with record... | |
| Which preamps use 6922/6DJ8 tubes? @strateahed That’s funny how the AI text is pretty well written and seems confident, however it is totally wrong on the tube complements! Most of those cited units don’t use any 6922 at all. The ET-5 appears to use a single 6922, and yet the AI ... | |
| Which preamps use 6922/6DJ8 tubes? I totally get OP’s line of reasoning - don't think it's weird at all 😅 6922 is a great tube for line stages - better than 12AX7 / 12AT7 / 12AU7 imo. But if you’re looking to use valuable NOS, then you have to be wary of designs that use a LOT of ... | |
| What Does It Take To Surpass A SME V? Is the Verismo a good match for a current injection phono? Ortofon specifically chose a less-ferrous armature for the Verismo (and A95, and Windfeld Ti), which reduces its output for a given coil (0.2mV from 7 ohms - compare to A90 at 0.27mV from ... | |
| Preamp comparison - Rogue Perseus and ARC LS25 MKII Also - I’ve used sets of both EH Gold and Sovtek 6H30 in both the ARC Ref 6 preamp and the Rogue Athena and Hera, going back several years. Not a lot of difference in these tubes, either way. The EH Golds are maaaaaybe a hair warmer. Like 1 - 2% m... |
