| Vacuum Tube preamp with my KRELL KAV 250a, a no no......WHY? I have an older Krell KAV amp that has been recapped and refreshed. A technician that I respect very much said do NOT use a vacuum tube preamp with my KAV 250, or any other Krell amp for that matter. Can someone with more technical knowledge th... | |
| My Caladan Impressons I’m intrigued by these open baffle speakers. I just have a hard time imagining they have any kind of visceral impact in the bass/mid bass. Am I off base “bass”😃.? @mofojo Because they are open baffle, bass is emitted from the rear of the speak... | |
| 300B or 2a3 SET Class A for Heretic Model A? I also agree with the poster who said running low powered SETs gets you entrance to a cult, and it’s one where you can land on some magical combinations of speakers and amps. It’s all fun, so long as you don’t mind losing your eyebrows every on... | |
| High sensitivity (99) with mid powered (50 to 100 wpc/tube) amps? I think, however, if something happened in my life that allowed me to start (somewhat) fresh, I'd like to go the low powered SET route (I was specifically thinking about some of the Dennis Had stuff) with speakers in the high 90s. @immatthewj I... | |
| SUT help @bobsdevices Thanks! We occasionally run into customers who can't abide any phono noise despite the phono section being quieter (so inaudible) then the LP surfaces themselves. That kind of individual seems to value the noise floor over other char... | |
| Polarity of XLR to RCA @dtune If a US product, pin 2 of the XLR is the same is the tip of the TRS connection and is non-inverting, which should be the same is the center pin of the RCA. In Europe, the polarity of pins 2 and 3 is reversed. | |
| joule la150mkII- preamp @syhilly0107 Obviously Jud used different knobs over time. Before you do anything I'd call Rick at Signature Sound (he's one of our dealers) and see what he says. It really won't be worth it if you damage one of those controls! | |
| 300B or 2a3 SET Class A for Heretic Model A? It always bothers me when some asks about a lower power tube amp and someone chimes in with, get a higher powered amp. To me if you want a 300b, 2A3 or 45 amp get one. I have all three. I listen to music all day and at good volume and one room is... | |
| joule la150mkII- preamp @syhilly0107 They are held on by 2 Allen drive set screws, 1/16" driver takes them loose. DO NOT try to pull them off without loosening the screws!! You may find that the shaft of the control comes out with it. The balance control is nla and the ... | |
| 300B or 2a3 SET Class A for Heretic Model A? Well are 100db if that doesn’t work for 45… @superelmar exactly! You need about 6-7 dB more; type 45 amps are better suited for headphones. | |
| SUT help @bobsdevices Our phono sections are designed to work with LOMC cartridges directly. It seems where SUTs are best suited is if the phono section is designed for high output MM cartridges. That's always been their traditional use. | |
| My Caladan Impressons @prismvineyards Give the speakers time to break in. Also make sure they have at least 5 feet from the wall behind them and you might want to work with how toed in they are- these things have a big effect on how they present. | |
| High sensitivity (99) with mid powered (50 to 100 wpc/tube) amps? @immatthewj @hilde45 There's no downside to running a bit more power on a higher efficiency speaker! I've done it for years (my speakers are 98dB). I've found that many lower powered amps make just as much noise floor as higher powered amps, so no... | |
| 300B or 2a3 SET Class A for Heretic Model A? @superelmar A lot depends on your room size. When you are using SETs, if you run them past about 20-25% of full power they tend to make more higher ordered harmonics, which, since the power is usually on transients, tends to make the amp sound mor... | |
| Living With A Class A Tube Amp Amplifiers employing tubes often present a larger, deeper sound stage that some term ‘halographic.’ Tubes also have a distinctive distortion signature that I notice most with guitar treble. Jimi Hendrix and Stevie Ray Vaughan solos sound like the... |
