| HELP AFTER MY MODS, My tweeters are subdued and weak- Mirage M1 Heard a pair once.Bloody nice speaker in standard form, if they’re working fine. Great bass definition even when driven by a 80w P/P pentode. But they need air around them, because of the rear firing tweeter. Like this.https://s3-us-wes... | |
| Plinius Hiato Off hand what brand/model would be a good upgrade from the Parasound Halo? Pass is also Mosfet, I think. Seeing now your looking at poweramps, a step up would be the JC1 Halo’s in high bias Class-A mode.This is Stereophile's quote to the load th... | |
| Plinius Hiato The Martin Logan’s can go down to 1ohm load, with very high - phase angle from 1.5khz to 15khz The best is the Halo for these impedance’s as it uses Bi-Polar output devices which are better for this type of low impedance, the Pinius I believe (che... | |
| New Schiit Freya or used Conrad Johnson PV-10AL/BL, or? A little more analysing here to find the best of what to choose from, instead of just plucking from the air.If you look at the input sensitivities of both Vincent SP-331 or McIntosh MC2200, they need very little to drive them to full output, only ... | |
| Reliable burn-in service for cables and outlets So? little more knowledge is good, so long as it doesn't sprout from the book of voodoo.Cheers George | |
| Synergistic Red Fuse ... Hope the fuse is a black and in the right way round.Cheers George | |
| Reliable burn-in service for cables and outlets Flipping the direction of the IC’s from source to linestage, the vocals become unintelligible and music sounds odd.Put them back as the arrows indicate, vocals/music fine.Pay attention to those arrows! Yes if you use rca interconnects with two wi... | |
| Gungnir sound before and after multi-bit upgrade? I got the Freya mostly to satisfy my curiosity on a passive Passive mode, will give you the most transparency of any preamp.Just have to make sure your poweramp is the industry standard of 47kohm input impedance or higher, which most are. And the... | |
| Gungnir sound before and after multi-bit upgrade? Good to hear GhosthouseMultibit (properly implemented), compared Delta Sigma doing RedBook (pcm) replay, to me has bigger more powerful presentation, with deeper wider sound stage, and with more foot tapping bounce to the music. Delta Sigma seems ... | |
| Synergistic Red Fuse ... Yeah, welcome back Frank, didn’t know about this, wondered why all went quiet for a while, thought you just sat out out for rounds 9 and 10. Back into it yeah, ding, round 11.Cheers George | |
| Reliable burn-in service for cables and outlets For you interconnects, use this free pink noise generator on line. Use the pink noise up full, feed it into your interconnect, terminate the other end of your interconnect cable with 1/2w 1kohm resistor let it run all night. all week, for what goo... | |
| Thinking of replacing my Bat spaceheater with class D, real world thoughts please Dodged a bullet. So glad you kept the BAT before getting a Class-D.The day will come though when that BAT will become a door stop, or boat anchor, and that will be when Class-D finally get a much higher switching frequency (the technology is on th... | |
| Anyone try KT150 in Primaluna Dialogue Premium HP Do your homework, and make sure the tube 6.3v heater circuit can take the extra current, as the heater voltage can sag.As the EL34 take 1.5A each and the KT150 can take 2A each. So for 4 x EL34 = 6A which the Prima Luna can take.But 4 x KT150 = 8A... | |
| Any comments on DAC going direct to power amplifier or to pre-ampliifer? Yes it’s a common big mistake when owners use their CDP/DAC internal vc well below 50% of full and say it’s rubbish compared to a preamp, what their hearing is only maybe 10 or 12bit resolution instead of 16-24bit. If you have too much gain and it... | |
| Any comments on DAC going direct to power amplifier or to pre-ampliifer? I find that even the best digital components with well executed designs (dCS, Berkeley Audio Design, Bricasti, Weiss, etc) are still no substitute for a well designed, quality analog preamp. Yes, they can be, and better, but you must use them in ... |
