| Okay to use RCA adapter on a fully balanced amp? Another option is to use a Schiit EQ (Lokius or Loki Max). Plug an RCA from the preamp into the EQ input and use the EQ output XLR to go to the amp. It will convert to balanced output voltage. The EQ is probably a lot quieter that an RCA/XLR adapt... | |
| Break In Failed A few thoughts on the subject: In my experience the only thing that sounds worse new out of the box is a vacuum tube. Do driver manufacturers run new production drivers for hundreds of hours to "break in" before testing, or do they test them rig... | |
| FUSE Question...Very Confused Please Help ! You have to be careful because equipment voltage rating is different from actual wall voltage. The fuse size is determined from the transformer power rating using the equipment rating and then the wall voltage: 230V x 2.5A = 575VA Since you are ... | |
| Stored, used, crossover capacitor burn in / reforming time Cap data sheets do not spec "burn in" time to reach rated capacitance. PP caps do not dry up like electrolytics so there is no dielectric reform to worry about. Once you put the caps back in they will perform the same way they did all these years ... | |
| Ground voltage!! Order one of these and plug it into each outlet: https://www.amazon.com/Sperry-Instruments-GFI6302-Receptacle-Professional/dp/B000RUL2UU/ref=sr_1_7?crid=1BOV06ZTC7KV7&keywords=receptacle+tester&qid=1667607178&qu=eyJxc2MiOiI0LjMzIiwicX... | |
| Isolated ground in dedicated room/new construction? I would steer clear of 2-wire Romex. The hot and neutral run parallel along the flat length and this creates an RFI antenna. I use 10/3 Romex (orange sheathing) because the three wires are twisted, which helps attenuate common mode noise. I use th... | |
| At this level of high(er) end audio why not offer balanced connections? Yes, examples would be helpful so we can see where you want this discussion to go. Off the top of my head: Pass, darTZeel, Soulution, Levinson, Krell, FM Acoustics offer both balanced and XLR. D'Agostino offers only XLR, so that turns it around a ... | |
| Run with 240volt here in Thailand or use Step down transformer? If you must have something that can only run on 120V then you have no choice about the transformer. Other than that I would stick to the voltage that's compatible with the wall outlets. There is no performance change one way or the other with equi... | |
| Hocus =- Ansuz Sortz - Pocus I don't see why these things are orders of magnitude more expensive than Cardas RCA caps. EMI is very effectively suppressed by copper, plated steel, and copper/nickel alloy. I tried the Cardas caps in the unused RCA jacks of my preamp and cannot ... | |
| Is this safe? There is always the risk of shock, and with tubes there can be hundreds of volts lurking about. Has nothing to do whether it's an amplifier or a CD player, high voltages are just as lethal in either. The only way to know for sure is to use a dig... | |
| Dedicated circuits A 30-amp breaker requires a 30-amp rated receptacle or you will be in violation of your local building/electrical codes. The fuse rating of the equipment is not a safe alternative because something else can be plugged into that outlet and it may n... | |
| Harmonic distortion inquiry THD is a ratio of voltages (harmonics to fundamental) so it can be expressed as dB. For 0.03% THD the distortion attenuation is: dB = 20 Log [THD/100] or 20 Log [0.03/100] = -70.5 Now all you have to do is add the three devices (-70.5 * 3) and t... | |
| A Question About Time Alignment Suppose you (the woofer) hit the bass keys of the piano and someone else (the tweeter) hits the treble keys, but not at the same time. The music is no longer time aligned. But if you both hit the keys at the same time, is is aligned even though on... | |
| Things I don‘t know You have to look at this from a market point of view. Do the engineers at Toyota not know how to design a vehicle that rides like a Rolls Royce or a performs like a Ferrari SF90? Whether they do or not is irrelevant because the market cannot bear... | |
| Grounding questions First things first: Power on the amplifier without the preamp. If the hum goes away then connect the preamp. If still no hum connect the source components one at a time to the preamp until there's humming. Then we can narrow it down. |
