In comparison from legato2and 3 the 3 is more mellow , less digitized flareups in the high frequency range., most noticeable and appreciated if running full range drivers such as in my case at hand. besides i run a tripath amp without coupling capacitors also so it's all the way cap less. My buffaloII does not activate the mute and lock process anymore so i'm looking for another bII or something in the same range since i'm using Arduino at 1 end and Wave I/O at the other . regards regis

i have since my last post added arduino uno to the buffaloII dac and remained in synchronous mode with Wave I/O . It was quite stable operating the whole setup . I have since stumbled upon a problem that i cannot shake . i heard a click and wondered what it was, i looked and saw that the dac had unlocked and now will never lock back on., everything seems normal at first look and pick and pokes with the multimeter, and backtracking to see what is wrong and it seems and i wouldn't doubt that the chip's dac might be the corporate.i have tried another off the shelf dac to test from the source and my I2S signal and toslink signal is strong as ever so no issue there. nothing unusual that appears out of sync as far as i can see but then again what do i know . guess i will have to get in line reluctantly and maybe order another dac, ah well... regards regis After nick picking some more, i have found that a short had developped over time, least i now know it's a short that can be fixed and won't have to stand in line waiting for another dac. will rewire the WaveI/O in sync.,rewire the arduino and see how it goes. regards regis

barrows i'm using a PC Power & Cooling,INC .for the PC's supply. The power supply for isolating the USB bus is a separate Placid HD . at 5V at 475mA . I have it connected to synchronous clocking on the ESS., that was an improvement . I could try increasing the current on placid BP , it might do something interesting in adding warmth. I hear good review's on the newly released and sold out NCore . How many TX-2575 resistors are required , can you approximate.. tks for your output barrows regards regis

greeting Barrows Indeed when i was using LegatoII i used it in stock mode , i now run the BuffaloII with legato3"1 which gives it or rather it eliminates the glassy tones in the upper high and mids ., i'm using a full Range driver and being only a 5" driver it didn't help with the LegatoII. On Legato3.1 i still have some of that high spirited glassy nuances in the upper notes but it is attenuated with Legato 3.1., so that's a step forward. Heard somewhere that to attenuate even more so the high metal pitch sound from a too effecient driver one can put in Takman resistors to replace the metal film resistors., so many of them when reading the Bom file , don't know were to start but it's a start but i need help in that area to know which one are relevant to the situation at hand . I did go the isolation route for the USB Bus to the WaveI/O inputs, thus eliminating noise from the PC, it wasn't a necessary cure in my case due to already having my home made PC system with quality power supply., but had to try it to see if it would improve . Other thing i tried is switch off the 3th switch which controls the FIR on the B.II and it changed to sound spectrum to a evenly smoother sound across the board,at the cost of sharper pitch noise. I'm really thinking hard about changing from metal-film resistors to Takman carbon resistors , it could possibly take some of that metal sound some more ., but i need help in that area to figure which ones to change. cheers regis.

Indeed, my legato 2 still has it's original components and stored for now,i kept note on the mods that you implemented for further possibilities. I do get streaming up to 4690kbps@192HZ from my pc's usb bus,therefore i assume my usb2 line from the pc delivers at least 5V @ 430Ma. but i don't know if there is a noise issue with the usb bus so with the awaiting placid HD coming in, i will test for comparison if noise was an issue.

tell tale pic. in there somewhere

The outcome of powering my master-clock to Buffalo II in synchronous mode yields great satisfactory results for the system that i'm using ,i had previously used Legato 2 to run Buffalo II but unsatisfied with over-all sound, but when Legato 3.1 came out it was mentioned somewhere that it yielded good results if, one was using full-range drivers and so it did, yield less glare, output capacitor-less legato3.1 does that for my system., less glare and a more relaxed overall less fatiguing listening experience, and now with WaveI/O added in the picture in synchronous mode, naturally it goes up 1 notch again, in giving a more relaxed presentation. As you say nothing is missing,there is less digital noise between the musical instruments,therefore darker background as they say., more power to for the volume control. I have yet to fiddle with my placid BP to power the incoming usb-bus going to the Wave card, i cannot blindly trust the incoming voltage from the usb-bus.Trying to gather info.as to how to hook up Placid to drive incoming usb signal to Wave .
