| Coaxials - Reality vs. Experience? The real purpose of a coincident source driver is because of the waveguide affect of placing the tweeter in the center of the bass driver. A waveguide to a tweeter extends the frequency response lower allowing a 2 way to utilize a larger driver f... | |
| Coaxials - Reality vs. Experience? I guess class D hybrid and Walsh drivers are as hip as I can get but my point was not the age of the design but that there are successful designs of most all configurations and coax drivers are not a magic tonic. @russ69 I don’t think anyone in... | |
| Coaxials - Reality vs. Experience? Maybe you could be more specific about the sound qualities you ascribe to concentric drivers. @tomcy6 For me: Coherent, natural sound with solid & sharp imaging, because the tweeter and mid/woofer covering the critical midrange crossover... | |
| Hagerman Trumpet MC (12AX7 Tube Suggestions) Well I actually tried a pair of 5751 in the 1st 12AX7 slots. It sounds great - this is an improvement over the Russian Tung-Sol gold pin 12AX7 I had in there, for sure. Sweeter midrange, a little more 3D - as is often the case going from Russian t... | |
| can you please help me around how to use my first tube amp? Guys - Rogue amps have the bias meter built in lol. He doesn’t need to run out for a multimeter. | |
| Coaxials - Reality vs. Experience? In your opinion, are they great because they are Tannoy or because they are coaxial? @erik_squires That’s a good question! Thinking on it, I’ve somehow managed to avoid hearing KEFs and most other coaxials. I have heard Thiel CS7.2, which featu... | |
| Coaxials - Reality vs. Experience? Tannoy dual-concentrics blew me away when I first heard them, and basically converted me to a Tannoy owner for life. I presently own 5 pairs! As a young man I actually transitioned over to speakers from high-end headphones; the Tannoy DC’s coheren... | |
| Need help diagnosing a preamp problem I recently had a channel suddenly go out on an EAR MC-4 SUT. It turns out the culprit was the left output RCA jack! Upon opening that jack up, tech found a lot of extra solder cruft that was causing it to intermittently short out. Rare, but it hap... | |
| can you please help me around how to use my first tube amp? An imbalance in bias within a push/pull pair (the two KT120 on the left form one such pair; the 2 on the right are the other), or far too low of a bias, will cause audible distortion. It can vary, but expect either a scratchy or choppy kind of inc... | |
| can you please help me around how to use my first tube amp? Best way forward is to call Rogue and ask for a rundown. They’re exceedingly helpful. But following is my rundown: I assume the amp has been run with these KT120 for a while? The bias will have been adjusted for each specific tube, so you need to... | |
| Hagerman Trumpet MC (12AX7 Tube Suggestions) One more note on the 5751 tubes tangent - the absolute sweetest sounding of the GE 5751 TM BP are a specific variant only produced between 1953 and 1954. This variant has unusual silver colored metal "clips" crimped over the plate "ears" that norm... | |
| Hagerman Trumpet MC (12AX7 Tube Suggestions) @djohn Awesome! So glad you’re enjoying it :) Just this past week I’ve been playing the Trumpet MC with Plantinum grade gold pin Tung-Sol (Russia) 12AX7 from Upscale Audio - no noise problems there. Maybe Viva just doesn’t like selecting them f... | |
| Hagerman Trumpet MC (12AX7 Tube Suggestions) Telefunken and Mazda (silver plates) 12ax7 are great if you want to amp up detail. The smooth plate Teles are warmer; ribbed plates are a bit more dynamic but also touch brighter. Mazda silver are the best omg - but a tad bright and expensive! The... | |
| New Cartridge or New Preamp I doubt the RP-1’s onboard phono will tap the capabilities of your existing Bronze and Black, much less a more expensive MC. Lots of good choices in the 2K - 3K range, including the Rogue Ares. Lots of decent choices in the 1K - 2K range too. For ... | |
| When were the best tube amps made? @alexberger Which modern 6SN7 are better than NOS? I currently use Ken-Rad VT-231 from the 1940s in the input stage of my integrated 300B SET. They are not the most expensive NOS but still to change the pair of these tubes is expensive for me. ... |
