How I ended up with this 2ndary set up I don't know? But I like it for some music. Clean, fast, clear, never heard k701s sound so smooth.

The Asgard is a wonderful amp!

Very cool, I like the Asgard on its side doubling as a HP stand, great idea!  On a side note, give a shot to plugging that beautiful power cable into a decent UPS that has AVR (Active Voltage Regulation) and Pure Sine Wave (PSW), which will insulate you from the rest of the rather utilitarian wiring from the wall that you are plugged into all the way to the power station, and give you nice clean power 100% of the time.  It also completely isolates you from anomalies in power from doing damage to your gear... for both under or overvoltage scenarios.  The power supplies in most gear do a great job of delivering clean power after rectification already, but if you are gonna go with a power cable like that, might as well take care of the rest of the power chain.  Plus, when the power goes out you can still listen to your tunes :D.

 

They make AVR UPS's for AV gear, but they are typically pretty expensive relative to the same basic functionality you would get from something like this for $169 shipped (if you were in the US, not sure how much where you are):  http://www.amazon.com/CyberPower-CP1350PFCLCD-Sinewave-Compatible-Mini-Tower/dp/B00429N19M.  They have a couple of lower power ones (1000VA for $148, 850VA for $118), but the 1350VA is the first one with USB charging ports, which in combination with the extra capacity, is totally worth it to me at least, I love the USB charging ports!  I have been a diehard APCC guy for 20+ years, but after trying these at 2/3 or so of the price of the similar APCC model, they are just as good according to the o-scope.

 

NOTE:  There are model cheaper than this that look similar, but there is typically one key difference.  These output PSW(not really pure, that part is marketing, but close enough) when you are on battery power, where the cheaper ones output an ugly square wave given their inverters to convert DC to AC suck :).  A couple of my PCs will will shutdown the second they get hit with this square wave, so I don't have any of those anymore :).  If you are buying one of these for clean power(not filter like a Monster power filter, but actually regulate), then might as well get one that has clean sine wave output itself!  If you already have a power filter then you can run them in series where filter is plugged into UPS, UPS to wall.  Some at Monster will say not to do that (as do the instructions), but I spoke with an engineer for Monster (I had HTS-5ks for each of my stacks for a while) and he assured me it was perfectly fine (which is exactly what made sense, and why I escalated the question to engineering in the first place given the manual didn't make any sense, the trick is to make sure everything is grounded correctly).

 

FYI, I was an ASE certified (electronic circuit and diagnosis was one of the certs) line technician(aka mechanic) for Toyota, then Nuclear Electrician in the Navy (NEC 3353, I worked on subs on the reactors, not on the nuclear payloads), then EE from UT @ Austin, and have been working in data center ever since(15 years now), I looove this stuff, so interesting :D.

Yes, when we built this place we actually put our own power pole at the street and added two power lines. I was in the process of buying a Richard Gray substation, but my wife had a cow and bawked at the price. I also had plans for new copper terminations for both this Epiphany cord and my main "Fat Boy" PC.


I didn't think I would hear a change with the Asgard but I think I do. I do hear major SQ changes with the Woo amps. But I do agree with you that in some systems and some places in the world, pure sine wave filtering and power regeneration is key for optimal sound.

Talking with on location movie sound track producers was a treat. They have to clean up all the AC coming from the on location generators before getting to the recorders and mics. For them reducing the basic hum is imparitive.

I'm not sure though I would hear a big improvement in this rudimentary system, but do agree that our sound quality is a small stack of improvements slowly stacked on top of one another until a greater end result is multiplied. Lol

This finding small improvement is a matter of tinkering and not afraid of trying stuff that at first would seem silly. My CD player is in the shop and I'm not 100% happy with the other DAC choices I have now. In fact the timing of the little iPods 16bit 44.1kHz DAC adds something I still don't believe I'm getting with USB cords to DAC. I still will explore the Apple CCK option and am excited to read about how many are using new programs in IPods and iPhones to stream out higher bit/kHz files. I do believe if anything they seem to hold a little more "air" between the instruments. Also though I think 16 bit if done right is really all you need.


Yes, if your ever see the Greek Audio You Tube video the guy is talking about how power to your gear is a huge part of getting optimal sound. I know using ribbon power cords and being enthusiastic about power plug to amp joining being a difference is true. The upstream power purification is maybe something I will attempt at a future date with more funding. I actually have a power surge regulator not being used. In this part of the world the power surges to electronics are not only responsible for turntables changing RPM speed but also hold the threat of actually destroying your electronic equipment in the process.


The link to the UPS sine wave tower is interesting. I used to sell equipment with generators on board and in the generator world a pure sine wave output was always wanted. I have also seen super elaborate filters that take the power you get at the line and guarantee your different ICs are getting the pure power they require. The amazing thing is just how many ICs you have around the house, opposed to thirty years ago when there was none.


The Asgard on the side is how Schiit Audio explain it is to be done to improve heat displacement as both sides of the case act as a heat radiator and having both sides exposed to air increases heat transfer out of the amp.
You are so correct in ultilizing the simple servo power regulators and I will start using mine. I actually have small IC chips replaced inside the power transformers to my computers here. At one point I was just buying new ones every couple of years as they were damaged by the power flux. Now I have my tech replace the little IC which burns out inside them. I get it done for $5, a nice difference from the $25 for a computer transformer.


On another note they always suggest that your home PC should have its own plug at home. It is having the PC plugged into a power strip having mutiple devices changing the load, thus causing the PC power supply to fail at a sooner time than normal.

Here is the new software for iProducts.

I think my other Fat Boy PC is a floating ground. Scary if the truth is there is no ground for your equipment. Ha, the one in my photo has ground. But still I never have hum issues. I am not sure if you can add ground to a floating ground power cord as there is no ground, right? I know nothing about this stuff, other than power cords change SQ.

Amps take line level and create gain and are thus creating something from nothing. When a thing is generated from nothing all the other support structures add to the equation IMO.



Your job sounds interesting and I can only imagine the process to secure pure power safety in data servers.

But not your average Glen...

 

 

 

 

I've had several bottles of this stuff over the years and, a bit like the 800's, each one was a bit (actually sometime drastically) different.  It's just one of the those things.

Nice picture looks great so appetizing, to bad i dont drink lol.

Lighting LODs are a different animal from what I read around here. The 30 pin LOD is the way to go on my older non-Lighting Apple products. I think I've seen it done with the CCK in the portable forum? Maybe someone can post a link?

For what it's worth I found the 5th gen Touch 16bit/48kHz DAC amp combo to be a surprise out. Not even using audiophile grade RCAs or adapters in place. It could be the bottleneck? It's either temporary or permanent? Don't know?


But ya, I'm doing the deadly no no with effectively two in line volume controls. And I krank em both, lol.


My CD player is at the shop so this is what I'm doing and love it. Another world in comparison to other set-ups I tried like a USB DAC or DVD CD 16bit/44.1 kHz player.


So ya, I'm a fan of trying stuff and just listening before settling on what I think I already know. Cheers!

Bypassing the OS7 EQs and ALAC player I'm now mainly using the VLC FLAC player. No longer do you see the VLC advertised as the free FLAC player for IOS 7 and above. It shows as only a player for photos and video. Except for some file recognition info, it plays 24 bit / 96 kHz files and regular lossless FLAC files same as it always did. Your Apple device will be shunted at the max 48 kHz until they start upgrading the DACs.

Still 16/44.1 done ruler flat is staggering if done right.

People with a lot of money are different. After you have had all the girl friends, had the 18000 square foot house and drove all your cars, there is nothing wrong with getting in trouble with the law. Just a normal chain of events in my opinion. But ya, you know he has some audio equipment. I have heard stories about celebrity stereos and they are one of a kind at times. Put into antique cases so no one can walk out with them at parties.
