| Wadia 20 Transport Here are the stripping details of the transport mechanism/laser onec you've got it out of the chassis to get to the those gears, similar model Teac/Wadia unit. https://ibb.co/26zgpzzCheers George | |
| Mojo Audio Mystique EVO Ideally, a system should have only one ground point to the mains through one mains lead. Because you can get small earth loops happening if everything has a mains earth plugAll equipment are grounded to each other via the interconnects from source... | |
| Anybody have ant thoughts re using 2 Herbie's tube dampers on 1 tube? Save your money and get these, not too tight just a snug fit, measure the diameter of your small and big tubes and reduce it by 2mm for the ID of the o-rings needed, for themThey are high temp very high quality silicone o-rings, for industrial pur... | |
| VTV Purifi amp models I have Hypex NC500 module’d monoblocks here at the moment, which are the same as the Belcanto Ref M600 monoblocks, except for they have Linear Power Supplies (LPS) instead of Switch Mode Supply (SMP) ones.And as much as I thought the Belcanto’s Re... | |
| The Truth About Preamps George, what analog source doesn’t absolutely need a preamplifier gain stage? Many of my Lightspeed customers some have even post here if you search. On how good their TT sounds with a high gain (>68dB) phono stage direct into a passive attenu... | |
| Downside to R2R Ladder DACs? George, this is very true - two power supply caps in parallel have smaller ESR, And it’s great we can access cheap ones from our little Chinese buddies who make them complete ready to go at what just our parts cost would be. Many more variation o... | |
| Monoblock Aegirs Any amp that is mono'd including these Aegir's have bridged output stages. And when that's done they DON"T drive the bass when it has low impedance as good as the same amp in stereo mode.As a bridged output stage as in the mono'd Aegir, Is higher ... | |
| Downside to R2R Ladder DACs? I don’t know much about R2R Dacs of 10 years ago,but when I see the inside of a Denafrips R2R Dac with over 400 capacitors I wonder more about the sound impact of any number of those caps going bad over time It’s very good for power supplies, as m... | |
| The Truth About Preamps FACT!!! most sources today that have variable volume output have output stages that equal and sometimes better most preamps, especially tube ones. If you need to insert a preamp to "color/distort" the sound you your needs, then that means you don’... | |
| Monoblock Aegirs But, when the midrange driver is being driven by a different amplifier than the woofer, (and in these cases by amplifiers not chosen for the similarity in their sounds, but rather for the difference in their sounds), the blending between the drive... | |
| Downside to R2R Ladder DACs? @abraxalito, think I have some of them laying around, do you know if they're unity gain stable, no mention in the data sheet.Cheers George | |
| Downside to R2R Ladder DACs? A sales person I generally trust told me to steer clear of used R2R DACs, since their reliance on high precision resistors causes them to sound best when new, and degrade fairly quickly. All I can say is, typical sales persons BS to get a sale on... | |
| Monoblock Aegirs That’s a really bad idea. Particularly for a Vandersteen which has been phase aligned with such care in it’s design. Impossible, if gains of both the amps are adjusted with the Sys to be the same, Vadersteen’s phase alignment will be unaffected a... | |
| Monoblock Aegirs Vidar is not a Lin topology. When used as a monoblock, it is simply amplifying a differential signal. It is not bridged." This only applies to the input stage, output stage’s negative speaker terminal is still at ground potential therefore will on... | |
| Monoblock Aegirs 395garrison OP Thanks, appreciate the info on the sound quality issues caused by bridging, I had never looked in to it. Using both had crossed my mind but I had always read that when bi-amping the amps should be of the same type. They are very m... |
