| Best Tube PreAmp - McIntosh vs. Audio Research vs. VAC vs. Atma-Sphere If this is the case, I think you’d be well served to pursue a tubed pre that can deactivate the tubes when using the HT bypass. @soix The problem you have with this approach is the ability to drive interconnect cables in such a way that the cab... | |
| Dustcover Blues Look at my system page and you can see where the turntable is. It is on a granite slab sitting on a built in walnt equipment/record cabinet (which I made) which rests on a concrete slab. The uprights are 1 7/16" plywood. All the shelves are brace... | |
| Suggestions for high efficiency speakers? @fosolitude I think its a good idea to replace your Joseph speakers, which are good speakers but simply not efficient enough to really take advantage of what the Jota does. To do that, the speaker should not expect the amp to be pushed past about ... | |
| How to Improve Gain for RCA on Preamp. Can it be done? Another plagiarising millercarbon cut n paste post goes wrong @tsushima1 There are several ways to interpret your comment; just so you know, Atma-Sphere built the first balanced line preamps offered to home audio back in 1989. We got a paten... | |
| Preamp:...Add A Pass-Through For Home Theater If your preamp has a good quality volume control there's really no need for a home theater bypass. @reubent is correct. | |
| Dustcover Blues The bass is due to the boundary effect. Yes. But it appears you have a standing wave; if you were to break that up the boundary effect might be a bit reduced (that's how it worked out in my room anyway...). From how you've written about this, i... | |
| Dustcover Blues You can see that up against the side wall the bass is way up My surmise is that is your room boundary effect and may also be complicated by a standing wave (looks like you have cancellation in the center of the room). A distributed bass array m... | |
| A guy asks a question about high efficiency speakers........ I posted that and I have no idea why it was canceled. Put it up again. The moderaters have been working hard to remove a ton of spam and your thread probably was removed accidentally. | |
| RCA 9289 tube amplifiers I thought it amusing Ralph weighed in here.... One of my employees refurbished a pair of the little brothers to this amp, that he got from an old theater. IIRC they made about 60 watts using a pair of 6550s. | |
| How to Improve Gain for RCA on Preamp. Can it be done? Always like this with RCA vs XLR. Technically, gain is the amount by which the input signal is multiplied. Gain is always fixed. Gain is fixed in amps, gain is fixed in preamps. You do not change gain other than by redesigning or modifying the am... | |
| Dustcover Blues Whether its Helmholz or not isn't important. Resonance is. This isn't the first time I've seen this. Since most high end machines aren't meant to be used with the dust cover down (if they even have one) the dust cover may well not have been inclu... | |
| Turntable versus tonearm versus cartridge: which is MOST important? how come I always have to take the heat for dissing unipivot tonearms? That's what we pay you for, right? | |
| Horn speakers are really bright? The trick with horns is to take advantage of their controlled directivity- you can use that to minimize side wall reflections, thus allowing them to be smoother than a lot of non-horn systems. | |
| Component grounding I installed the nylon washer between the chassis and the ground wire ring. That doesn't sound right! If there is a connection to the chassis (and I'm assuming it comes from the center pin of the IEC connector) it would not be insulated from the... | |
| Turntable versus tonearm versus cartridge: which is MOST important? Ralph, look at it this way, your bike is the turntable and your legs are the cartridge. You know darn well what happens when they fail:-) That anaogy might be even worse than the one suggested earlier 😂 There is a vehicle analogy that I use. I... |
