Jamesroy Posted August 23, 2015 Author Share Posted August 23, 2015 I said in laymen's terms. I'm not as advanced as most of you guy's and gal's but I can here differences. I have my nano up to 75% and my pre amp at -22dB and that seems to be the sweet spot. Many have told me to go to 100% on my DAC but at that I seem to get a bit of distortion at around -28 on my pre amp. Now I can't tell you why I can only tell you what my ears hear. Thanks Reason for this final post on REGEN is because I'm in a place that I can order one on Monday. Link to comment

Paradigm 100 speakers Jamesroy - I think that the Audiostream article linked below does a really good job of describing what the Regen does and references the contributions of the developers to the description. What exactly it will do for you in your system as an owner only your ears will discern but by and large the reviews are positive. It might help to think of your ifi DAC as not just a "DAC" but a collection of subsystems that collectively are your ifi DAC - power supply, clock, chips, USB interfaces, volume attenuation, etc. The Regen helps to optimize the load associated with the USB input interface of your DAC so that it's inherent contribution to noise affecting signal integrity.

Have you tried connecting the DAC straight to the amp yet?

ted_b Posted August 23, 2015 Share Posted August 23, 2015 1) Why another Regen thread? The (literally) thousands of posts on the 10 or so threads are enough to get educated. Most of the posts (and, as stated, the nice Audiostream review, etc) are not too technical. 2) Why a Network forum thread? Nothing in the OP's system is network related at all. I, personally, would not make the Regen your next move (don;t get me wrong; I LOVE mine) I would first figure out why the Nano, at 1.75V at 100%, causes distortion in your system. Something else is wrong, cuz 1.75V (even at 100 ohms) is roughly normal line level out (2V) so your downstream stuff should not have any issue with it. A Regen at this point, is premature IMHO.

Jamesroy Posted August 23, 2015 Author Share Posted August 23, 2015 OK here goes B&K power amp and swithched power protector into wall AC.

Kanex Thunderbolt to usb 3 adapter into Mac Thunderbolt and external HD into Kanex usb. Mouse into other side of Mac usb. rca's out of ifi nano into B&K pre amp. Thank you Link to comment
4est Posted August 23, 2015 Share Posted August 23, 2015 Your problem is more likely at your pre amp. What input to the b&k are you using for the nano?

elcorso Posted August 23, 2015 Share Posted August 23, 2015 Jamesroy, USB3 could be very noisy. Please try your music library from another non USB HD, like Thunderbolt, that is available on your Mac Book Pro. Or better FireWire, with and Thunderbolt to FireWire adapter. Could be a 'noise conflict' between your iFi Nano USB port and the USB port on 4TB usb3 WD external Hard drive. I don't think the USB REGEN can solve this noise issue, because it is not a filter per se. Roch Link to comment

Jamesroy Posted August 23, 2015 Author Share Posted August 23, 2015 I don't have a non usb external HD if thats what your suggesting. and my internal flash drive on my Mac Book is down to 217GB available. Should I try another external. I do have a WD 2TB Firewire 800 usb2 hows that? Link to comment
Booster MPS Posted August 23, 2015 Share Posted August 23, 2015 I don't have a non usb external HD if thats what your suggesting. and my internal flash drive on my Mac Book is down to 217GB available. Should I try another external. I do have a WD 2TB Firewire 800 usb2 hows that? You could try another external, however if I were trying to isolate the current USB 3 drive as a source of the gain related noise issue, I would disconnect the drive and move a few familiar test songs over to your current laptop and play them locally. When using a pre it would be ideal to have the DAC attenuation at 0% (all the way up) and control volume with your pre. Using the other WD would maybe be the next step if I were in your shoes. What software are you running to play music? Somewhat related, are there any other potential sources of EMI/EMF noise in the vicinity? TV's, dimmer switches, noisy three phase motors on the same electrical circuit, sources of ground loops? Might help to just "step back" and look at other causes. Link to comment
Jamesroy Posted August 23, 2015 Author Share Posted August 23, 2015 Thanks, I'm using A+ My stereo is set up right under my TV. But none of my TV is in the same AC connect but other AC plugs close by about 8ft from my AC where my Mac and voltage protector is. And btw the voltage connector is very short AC cable about 2ft and not an expensive one. I'm on a tight budget, my main job as a grandfather is taking care of my two Special Needs grand kids. There doing as well as can be expected. I'm a Photographer/Graphic Designer. So I'm now copying over all my Photographs from the usb2 external HD to the 4TB usb3 and when thats finished I'll copy my music to the usb 2 that use to have my photo's in it. Then I'll test again. I'll connect the usb 2 into the Kanex which is going into the thunderbolt connection if I can. Link to comment
Jud Posted August 23, 2015 Share Posted August 23, 2015 Use Firewire 800 between music HD and computer. Try connecting the Nano directly to the amp and see how it sounds. Is it better or worse than with the pre-amp? One never knows, do one? - Fats Waller The fairest thing we can experience is the mysterious.

Jamesroy Posted August 23, 2015 Author Share Posted August 23, 2015 Thanks, I was told in a post awhile back not to do that because my B&K is a balanced pre amp. I'm copying over all my stuff from a USB 3 external to a USB2 and will test that out. I'm ready to order the REGEN but after this morning a lot of doubt has been posted to me that it's a premature purchase at this point. Link to comment

Jamesroy Posted August 23, 2015 Author Share Posted August 23, 2015 Not sure if there balanced but at the time I bought my interconnects years ago they were around 100 bucks. Musiclink there kind that have the box on the cable and the directional arrow. Short 3ft. Not sure also gold connects. Link to comment
