Stupid question, but does the Qutest accept a range of voltages? or just 5V? I know USB is 5V standard, hence the specification. BUT, if this product DIDN't use USB, might it offer a range of voltages, like 5-6v? or 5-9v? AND no need to inform me that this would void the warrranty, I'm well...

TL;DR: Is the shannon nyquist sampling theorem wrong? Rob, Qutest owner here. In my quest too shape sound in my listening room I now have collected 11 ASC tube traps. Optimizing their placement however was a B****. Eventually after a year or so I figured it out, and this is the breakthrough...

Hi Rob. I remember one time you weren't so optimistic of the future of FPGA's, in the context of above and beyond 1 million taps, through to 256 million taps, in the near future. I don't have the exact quote on me :) I'm reading through The $37 Arrow DECA FPGA Board and they kinda trash a FPGA...

I think you are on to something. I understand it in a different technical context. Ever been so elated your "Jaw Dropped"? Ever had your heart drop out of your chest at something or someone very beautiful? I figure its the body relaxing, exhaling, releasing tension, and enjoying the moment. The...

Just throw $100-200 a month into audio equipment, ALWAYS buy used, buy for value and intrigue. Before you know it in 6 years you will have $7200-$14400 worth of used gear I've been doing this for about 5 years with speakers/amps. Figure I'm sitting on close to $6000 of used gear, probably paid...

Must be fun playing with high-end Glass cables. A technological step up, and the high end cables are dirt cheap compared to other type cables. I think Im going to end up in this game in the future.

It's a not so perfect, inelegant solution. Could be done though. That would put a Roon Nucleus into play (Which should be a perfect device short of ditching USB and going optical), but with this AND a wifi device I'm now out of Power slots, and one of my devices has to share a 2 set of power...

Recently I decided that I should look potentially replacing my laptop with an audiophile grade solution. This is when I started smashing my head against the wall. My main issue that complicated everything is that the Router is upstairs with the neighbors, and I dont have a hardwired connection...

Here is the Thread. I have one single Power Isolator that connects to the wall, and everything is run off that. Keeps a physical disconnect from the mains, and then has two separate outlets of 2 plugins. I run my Amplifier off one set, and Chord Qutest from the other. Laptop runs on battery...

I have read through Rob's opinion on the stock wall wart being sufficient, a battery eliminating any problems that may exist in the home power supply, the Qutest having galvanic isolation, and an unplugged laptop being ideal as well. I generally agree with everything Rob says. Certainly an...

Thanks for the input, as you can tell, I need some polish on some of those numbers. First off, yes, some of my numbers may have been halved or doubled up as I was confused. "The signed range of integer values that can be stored in 16 bits is −32,768 (−1 × 215) through 32,767 " or 65536. Then 24...

Ok, here goes. Long, and with bonuses, but in laymans terms. Took me forever to understand this. Bitrate is like a TV, there are vertical and horizontal columns of pixels. Horizontal X Vertical = pixels A 1080p tv has 1920 pixels across and 1080 pixels high. The total pixels are like the...

I gave up my headphone journey about 4 years ago and started on a stereo system. Given the money I have sunk into that, it seems a little more reasonable to add a nice headphone setup. Previously I have owned Shure Se-846 and Grado PS1000's as my high end headphones. Im not sold on IEM's, Im...

Forgive me for not reading 1200+ pages, I own a Threshold S/150 II OB (90+ watts, about 20+ pure class A). Wondering if I can just unhook my speakers and hook up Stax headphones? I figure if I already have lots of class A...... Why not? I use ROON, and control the volume digitally from my...

Good to know. Not sure where I came up with the notion that Qutest could do the digital volume, but glad to be set straight so I have a better working knowledge. Robb's advice does go contrary to my next planned step, a First Watt Buffer Preamp (B1) to control volume and tweak channel balance of...

I have the advantage of having speakers that want 80-160 watts, so sending them 100 watts at full volume is only an issue for my ears and the neighbors. But +1 for good point, no physical volume control to manually turn down before playing music. This, as I understand it, is exactly what is...

Longtime Qutest owner with a new Class A/AB Power amp here.... Have a few questions that I think may have relevance to others in this thread. 1. How to calculate the theoretically appropriate Voltage output for Qutest to properly utilize the sweetspot of a Power Amp. 2. To pre-amp or not to...

Yesterday I disabled the microphone and speaker by "disabling" it in hardware manager. No improvement. I have also tried just about every setting, from default or low clock priority to big buffers. Computer shouldn't have an issue serving the files, hardware spec wise its overkill.

The issue is only with Qutest. I feed Qutest with the laptop, through Roon, bitperfect. I try to stay as pure as I can. I feel there is an error with the laptop not feeding Qutest properly. I have the Qutest drivers installed, and thats what drives me crazy. Can't think of what could be going wrong

I have recently run into an issue where some/most HD music files have static crackle and pops during the more intense portions of the song, similar to clipping, but at very low volume as well. I assume this is down to my Dell laptop/Realtek speakers, but even after trying everything I still...

It's been a while, so here is an update: The Qutest is the lynchpin of my system. Never before has my imagination left me blanked as to how something could even conceivably sound better. Of course it could sound better, but thats not the point. The point is, I have never heard better, can't...

Today marks the day I am moving on from MOJO, and I thought I would share my final impressions as I get my final listening sessions in. First off, I have owned the Mojo for about a year and a half now, and have never had a problem with it (Excluding Poly!). It is 100% plug and play, and idiot...

That's close, but doesn't quiet do what I am looking for. I am looking to Physically disconnect my PC, which means I need a network streamer that is good enough to act like a Chord Poly (but work) and connect to the Wifi upstairs (that my PC is also connected to) that I dont have access too. It...

Loving my Qutest streaming from Dell XPS 15 laptop. But would like to not have my laptop physically tied to the Qutest. Looking for advice on integrating a network streamer with both Qutest and Roon. I have read through all 177 pages, and there has been some talk of Network Streamers, but not...

Thank you,
