| Preamp - 18 dB Gain too low? Nguyen787,A doubling (2x) in voltage is (almost exactly) 6dB. A 10x in voltage is exactly 20dB. So for example if you have a 20x factor in gain then you could say: 20x = 2x * 10x = 6dB + 20dB = 26dBNote that dB values are always added together (si... | |
| Preamp - 18 dB Gain too low? The discrepancy between 1V sensitivity (for full rated power output) and 4V is 12dB -- huge! Grant Fidelity and Shuguang really need to get in sync on that one -- it's very confusing/misleading, on such an important spec that can make or break a s... | |
| kt77 vrs kt120 in Rogue M180s Jedinite24 and Samzx12,It was probably EH/New Sensor's fault. I think it was about 2-3 years ago when my audio dealer started complaining about a VERY bad run of EH KT88. They experienced an extremely high (early) failure rate of these tubes in th... | |
| How many watts per channel are enough? To be sure, you'll run out of headroom real quick once you start pushing that volume knob into loud territory. That's why they make efficient speakers and powerful amps!I'm a fan of efficient speakers for sure. Even those *honest* 93dB/Watt speake... | |
| How many watts per channel are enough? If by low-to-moderate volumes you mean peaks up to say 90dB (perhaps pushing to the mid/high 90s), then you should be fine, with ample headroom -- just don't do something silly like set the seating 20'+ away. I found 60 Watts/ch to be perfectly ad... | |
| kt77 vrs kt120 in Rogue M180s That's a very helpful comparison; thanks. I've been using KT120 in my Apollos for a while, and your description of their strengths closely reflects my own observations in replacing the EH KT90. I've been surprised and pleased at how all Rogue gear... | |
| Tannoy Black Value Dunno. How much is a golden unicorn worth? :)Make sure you advertise/auction to the Asian markets as well. | |
| What deserves more attention on Audiogon? Tannoy has a few fans here, emphasis on FEW -- Tannoy doesn't market strongly in North America, nor do they play the "game". Their original dual-concentric driver design from 1948 (they way pre-date both KEF and Klipsch) had been refined over the ... | |
| Bogus tubes from WI WI tubes? BTW, those bargains are not "premium" tubes by a longshot. Not all Amperex makes/vintages are created equal, etc. This adds a good dose of believability to the few listed prices. Certainly cheaper than a trusted domestic tube dealer, but quite bel... | |
| Bogus tubes from WI WI tubes? From what I scanned, the pictures are genuine vintage tubes. Many of these would hardly be worth forging anyways. Not that it's saying much -- pictures are easily sourced on the internet. No way to tell what quality of tube you'll actually receive... | |
| What is the best amplifier for Tannoy Kensington ? Al - thanks for the explanation. You are of course right, as usual! | |
| What is the best amplifier for Tannoy Kensington ? With big Tannoys the crossover frequency is relatively low at 1.1K, so the split -- % of power delivered to the woofer vs. the tweeter -- is closer to even. Those Tannoy tweeters have to be designed to handle a high amount of power. You could argu... | |
| Best 2-way room friendly speakers Tannoy dual-concentric driver'd models have controlled (due to the waveguide/horn tweeter, depending on model) AND symmetrical dispersion (i.e. acts like a point-source). Very room friendly while still yielding a comfortably sized sweet-spot. You ... | |
| Tannoy Differences The Glenair (10 and 15) sounds more natural -- and a bit more resolving -- than the DC8T. I imagine the Turnberry would be similar to the Glenair 10. All are very nice speakers for the money. The DC8T has a lot of power available down low, and is ... | |
| New tubes in Rogue M-180 Monoblocks The KT90 was thin/lean sounding compared to the KT120 in my Apollo monoblocks. Had a KT90 blow up after 1 year of light use -- a nasty short; sparks and a smoked resistor. No such issue with KT120 in the same time period -- that said, it's naive t... |
