| Ideas for low cost amplifiers with gain control Well that's an interesting application. Parasound Halo A-series are good amps with input sensitivity / gain pots that would work well for your needs. Not sure if you have criteria for new versus used. Two used A23 would fit well within your budget... | |
| Rogue M180 replacement tubes Several of us in the Rogue group over on FBook have discovered that we actually prefer KT88 over KT120 in the bigger Rogue amps. My direct experience is with Apollos, but M180 should be similar. The KT88 midrange is better, and that’s where the Ro... | |
| Phono cartridge noises @skyy75234 That's fair. I'm sure the JD9's sound & work great - just the specs always struck me as clearly "wrong". Probably a mistake that was never corrected. One of my first audiophile components was their JD100a CD player, and I remember... | |
| Ground wire hookup on a Step Up Transformer Question 9 times out of 10 (at least), the configuration you describe is optimal for eliminating hum. Since you don’t hear hum - leave it as is and enjoy! In general don’t add grounding links until they’re absolutely necessary. I have one odd SUT (Hagerma... | |
| Phono cartridge noises Sorry OP, I know how frustrating analog issues can be. When I had an Audio Research Reference 3SE Phono, I found its High Gain mode highly susceptible to noise from my plasma TV an adjacent room. It sounded like demonic gargling noises (lol). Oth... | |
| Clipping with Separates with change of Power Conditioner[?] I’d just plug the amp right into the wall, as recommended above. 80 Watts of rated power isn’t much. BUT - Class D amplifiers can have very high instantaneous peak power & current demands, and your new conditioner may be limiting this - perhap... | |
| Deciphering Integrated Specs - Step Up Matching Yeah, since the spec sheet states MM sensitivity of 2.5mV, and the line stage states sensitivity of 0.25V (= 250mV), that is a factor of 100x which is 10x * 10x = 20dB + 20dB = 40dB. That’s assuming the MM output pipes into the unbalanced input li... | |
| NOS Tube Recommendation for Quicksilver Phono Pre Amp 1. The 5751 can be substituted for the 12AX7, but ONLY in the input position. Using it in the gain position will cause the phono pre to not operate correctly. By "not operate correctly" I am sure he means that the RIAA EQ will fall a bit outsid... | |
| HiFi satisfaction and/ or Musical enjoyment A lot of this gels so much with my experiences so far. It’s been a struggle, at times. Paper / pulp / fiber midrange cones rock! Done right, they sound so natural. I love (some) Tannoys, and my favorites all have that paper midrange cone. I also r... | |
| It was the output tubes all along... Isn’t it really tough for tubes to get along with bass drivers? Isn’t that the real challenge herein? For the most part, the tubes are fine. If they’re struggling for your power needs, you just throw more parallel push-pull pairs at it (VAC’s M... | |
| NOS Tube Recommendation for Quicksilver Phono Pre Amp @crawfishdaddi OK, now I see you have stated the result seems a bit too warm. So you want something with a bit more "zing". In that case, you should check out the following: Mazda silver plate 12AX7 (expensive) Telefunken ribbed plate 12AX7 ... | |
| It was the output tubes all along... Soo. Back to point. @mulveling, since you’ve had extensive experience with the 200iq’s and the VAC master preamp, what would be your next tube to experiment with if you were in my shoes? Also, good luck with Helene-hopefully she powers down some ... | |
| Phono Preamp Selection Used there are actually a number of very good sounding MC stages at that price point. I’ve owned the Dynavector P75 (any version - I had a Mk 1!) and PS Audio GCPH. Both very good. The GCPH had a little hum at higher gain levels but I understand t... | |
| NOS Tube Recommendation for Quicksilver Phono Pre Amp GE 5751 TM BP are very nice tubes. Looks for the "silver clips" variant that was produced only from 1952 - 1954. It has bracing clips over the plate "ears" that poke out past the micas. Way over-the-top construction. Then the penny pinchers took h... | |
| Tannoy Canterbury, KEF Reference 5, Fyne Vintage Twelve, SF Serafino (Although I remember distinctly disliking the GRFs. Didn’t have that Tannoy midrange “magic” to me.). That's funny, because the GRF is basically a repackaged Yorkminster SE - same specs, driver, and porting - and I felt exactly the same about Y... |
