| What are ways to fix speaker dips in my speaker or audio room This can be fixed at the listening position with DSP at the expense of amplifier powerIn fact you may clip the amps with ease yet not fix the problem of a loss of bass. This is because the waveform is cancelling itself out. You can put a lot of p... | |
| Anyone try using a 5751 in place of a 12AT7? @jsbw The 12AT7 can handle a lot more current than the 5751 can. So you might run into saturation and/or a short lifespan with the latter.Another issue is bandwidth, and this plays a lot on how the feedback in the amp will behave. Feedback relies... | |
| Amplifiers in use with big Harbeths (Mon 40 series) that work very well i guess in my own experience, there is a fairly decent correlation between large woofers such as the single 12 inchers in big harbeths and spendors with the need for amplifier damping factor and control of the driver and its significant motor s... | |
| How long can a electrolytic capacitor last un-used? @hiendmmoe I should have said 'offer to the seller a price for the amp' in my last post. While we usually repair equipment on the side, at this point we are too busy to take in repairs. | |
| Recommendation for a highly resolving amp My friend uses his Spectrals to drive Quad ESLs and it sounds great. Would Soundlab ESL be that different than Quad?Depending on the Quads, yes. | |
| How long can a electrolytic capacitor last un-used? @hiendmmoe That was a while ago! If that's the amp you want, just consider replacing the filter caps. I would offer a price that reflects that repair cost, unless that's baked in already. | |
| Recommendation for a highly resolving amp My friend is a Spectral man, so he recommends a complete Spectral system. Along with all the MIT cables.Of course he would. But its not the best amp to use on Sound Labs IMO and IME. The best Sound Lab installations I've seen have used Purist Audi... | |
| Are Pre-Amps necessary? And to all, active preamps have volume controls as well, and most times not as good quality as the better passives pre's usually use. Also active pre's use many other distorting/colouring components in them. At least passive pre's usually only ... | |
| Amplifiers in use with big Harbeths (Mon 40 series) that work very well responds well to tube beauty but with the big woofers you will certainly give up something on the low end in the trade@jjss49 Just so you know, this statement is false. The size of the woofer has ***nothing*** whatsoever to do with how a tube amp ... | |
| The smoothest amp you've heard? Exactly how or why they would introduce phase shift down to 1/10th the cutoff frequency isn't revealed or explained.In any case, why just those frequencies? What about 20kHz cutoff frequency causing a 2kHz phase shift?A 20Hz cutoff will induce pha... | |
| Anyone try using a 5751 in place of a 12AT7? For starters, a 12BH7 might sub a 12AU7 pretty well, if the circuit can support the additional filament current, but its not a sub at all for a 12AT7!The difference in mu is significant with any tube. The circuit has to be optimized to take advant... | |
| I'm a Dummy, Tell Me About Turntable Mats I pay no attention to it, because my listening seat is far enough away from the turntable that I never hear it while I am trying to concentrate on what is coming out of the speakers. What’s the big deal?Anyway, I view it as a "problem" endemic to ... | |
| What are ways to fix speaker dips in my speaker or audio room I have recently hired an acoustic engineer and after a day of measuring room acoustics and he came back with what I needed to fix and one of my speakers dip at 54 HZ and would DSP help or a lot of bass traps in the frequency work better?@shawar... | |
| Are Pre-Amps necessary? It makes sense no pre would be most transparent, resolving, the straight wire concept. Go back earlier in this thread to see what a straight wire isn't always the most neutral. The problem is that a passive volume control isn't a bit of wire. If i... | |
| Tube question: any sonic difference in 6SN7 vs 6H30 vs 6H80 in the amp's signal position? The 6C33 was used for the power supply for the Mig's radio system and was remarkable for its power handling capabilities. The first audio amp using this tube was built by a Mr. Dakasue in 1977. The first American design to use this tube was the... |
