| 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... | |
| Component grounding No no, I meant the preamp section of the integrated. It has a feature that let's you bypass the preamp section and use the output control on the DAC instead. When I did this, the hum came back. I don't know what that means, but you're right, the ... | |
| RCA 9289 tube amplifiers Dad always favored rebuilding them with Sprague Orange Drop coupling capacitors. That is because back in those days they were the only game in town. A lot has changed since then! There is no way I'd use orange drops for any kind of rebuild or r... | |
| Turntable versus tonearm versus cartridge: which is MOST important? Is this all equal to audio? No. | |
| Component grounding @rfprice Hm. That kind of suggests an isssue with the amp. Have you tried other amps when the preamp is in the system? | |
| Half Speed Mastering Decca half speed mastered their classical LPs (London too). This was to avoid a resonance issue in their cutter system. Apparently it worked. | |
| Class A amplifier alternative? I think AGD might make a class D with the sort of power you need. |
