| Amplifier Power tubes - important to sound? Right out of the Mc 901 manual: The MC901 will function optimally with any correct tube type that is functioning within the design specifications of the MC901. Only when a Tube falls outside of the acceptable range will any diminishing of perfo... | |
| Those magical days when the HVAC is off After reading through the comments here, I have some work to do. My no HVAC baseline noise level, C weighted, is ~ 40 db! I can't avoid the white noise of HVAC on, as there is are two ducts and one return in the room, plus the system is in an ad... | |
| Graphene Sluggo - Unlocking Sonic Scenery @verafiaudio Yes, I am disappointed. The Lux and the VTL would have been the best options, covering both tube and SS, but with other fuses downstream from the sluggo and SDFB, neither makes a good platform for analysis. I guess I need to go amp... | |
| Graphene Sluggo - Unlocking Sonic Scenery @verafiaudio I was looking forward to giving this a try, but given the way it works with the AC line only, none of my SS amps will be agreeable. The Luxman has 5 different fuses, two of which are the AC line, but the rest are on the secondary si... | |
| Graphene Sluggo - Unlocking Sonic Scenery @verifiaudio "You are seemingly highly technical so the best option for me is to offer you a Fuse Box to try with a few differing Sluggos " Very kind of you to make this offer. Wish the SDFB had an external way to adjust trip rating. I have tw... | |
| Graphene Sluggo - Unlocking Sonic Scenery @verifiaudio As an op-ed to my prior comment, the inner workings of the SDFB are still of interest if the methodology can be modified to mimic the conventional fuse attributes. Does the SDFB use a relay or SS devices as the circuit make/break? | |
| Graphene Sluggo - Unlocking Sonic Scenery @verafiaudio "The "simple answer" is that FuseBox will hold 100% current rating indefinitely. When steady current consumption gets to 110% it will trip." Unfortunately, this characteristic will subtract dynamic replenishment from my system, whi... | |
| Graphene Sluggo - Unlocking Sonic Scenery @ verifiaudio "You are correct - no B+ or Speaker Fusing please - AC Mains ONLY. SDFB is very safe and has proven itself to be very reliable and easy to use. " That doesn't quite answer my question regarding the response time of the SDFB vs con... | |
| Graphene Sluggo - Unlocking Sonic Scenery As an avid audio enthusiast and repair/restoration tech, I'm always eager to learn about opportunities to improve existing gear. This post prompted a poke around the 'net to see what more could be gleaned from the SDFB. First of all, it appears ... | |
| What's the value in lots of capacitors inside a line stage preamp? If you have lots of capacitors in a line stage, presumably tube, preamp are primarily for filtering the power supply. Without going to the trouble of looking up that CJ pre schematic, there shouldn't be more than two coupling caps per channel....... | |
| Can you tell the difference between a $200 and a $200,000 guitar? As some have said, a great player will make an average guitar sound good, but it's like asking Mario Andretti to drive a Yugo in a race. Even a pair of $5000 guitars from the same luthier may sound different, as each piece of wood is unique. Wel... | |
| DAC suggestions for a reasonably modest system @cundare2 I was surprised not to see HFR until your post. But they are streamer DACs, so perhaps that was the reason. If you were to isolate the DAC portion only, aside from the comparison to the 103D, where would you position it in the spectr... | |
| DAC suggestions for a reasonably modest system @jji666 I had considered using the XLR outs with an adapter, but the balanced output voltage is twice that of the RCA, so I'd need to introduce some passive circuitry to attenuate. And in the random bit of music studio work I've done, adapting ... | |
| Do you trust your ears more than measurements? I use measurements for what they're good for, and use my ears for the rest. Most everything I have is vintage, so it winds up on the bench for safety and performance checks. If it's possible, I will listen first, then measure. We don't listen t... | |
| DAC suggestions for a reasonably modest system To wrap up, a few names I wasn't as familiar with, so that's very helpful as I narrow the choices. Seems like the Pontus is the budget stretch choice, the Yggy right behind it, and a host of good choices from there right down to pocket change lev... |
