I've used & rolled caps in a little single outlet conditioner on a 2010 mini w/8g ram both wirelessly & currentlyvia ethernet to a Modwright Transporter. The mini is stock fed via a G-raid & FireWire. I've always been easily able to hear the sonic signature of whatever caps r in the conditioner & whatever power cords r used going in to the C7. The caps I've used in the conditioner include JPX Premium, Sonicap Platinum, Multicaps, Mundorf SGO, Jupiter copper foil, CuTf V-caps, & Dueland Cast. Prs. Of .22s neutral to ground on orange hospital grade & Oyaide R-0s. On the whole houses 'general' circuit & any of the six dedicated 10g lines the differences r easily notable.I really don't understand someone claiming not to hear a difference of a Mac mini on a conditioner. In fact I'll make it easy, put the Duelands on the mini and the g-raid, put the CuTfs on the amps. Dac can go either way. You're done. If you want 'more' depth/colour vs resolution impact use a 3.3 SGO w/ the v-caps. You'll feel as if you got 'new' speakers...I know batteries can be very good. So can very expensive well built power supplies. I owned a 'stack' of Naimgear & paid dearly to claw my way up the power supply mountain w/ it's split rail 24v yada yada...Copper foil caps, on great outlets, neutral to ground following a CMC r very cheap in comparison, & just as good. Just don't tell the X/Y safety nazis.
Simply a confirmation on the bi-polar nature of the C-7 plug orientation. Nice to learn something new.Thanx. All things being equal, which offers better performance, the external linear power supplies or batteries?
So as for outboard power supplies I've looked at, they rely on filter caps to 'season' the output.Better or just different? I understand that getting rid of the snps will provide sonic benefits, so it's nice to know there is another levelyet. But conditioners can profoundly effect, even what one gets from a very meager power source.
I have an "09 Mini with the external brick. I have done nothing to the power. I have been on the fence for several reasons but mostly just think what's out there is too expensive. Paul Hynes has the most interesting product but I am not going to do business where someone wants money now for a product to be delivered in the future. Maybe a week or two is OK but months and years- no way.I also keep thinking that something better (like a reasonably priced server) is going to come along... but nothing yet. I might be enticed with a well thought out power supply in the $500 or less range. Beyond that, I'll just keep enjoying what I have and see what the future brings.
When a man like Paul Hynes has a year to year and a half backlog it is because his products are "that good" and he is working as quickly as possible to meet that demand.
Reasonable priced servers are available. They just don't really make it in SQ.
A dedicated power supply can be built for $500.00 or so. One that meets all of your needs. Problem is that is about the cost of components, packaging tme and shipping. Not a lot of "feed the family" built into that price.
Uh? Which means they don't exist , right?Well, I suppose that's why there isn't any out there on the market and why I haven't done anything to my Mini's power supply. We all have to make choices with our priorities, budgets, etc. The manufacturers have their thresholds and the consumer has his. Sometimes they meet and sometimes they don't.
Dave,I think you mentioned to me that you didn't have much luck w battery type power supplies with MM's. Care to elaborate?
I am certain that one could produce a battery supply which would work very, very well with a Mini, or any server for that matter.I use a battery supply in my custom server, and it is a far better way to go when doen right than any AC based supply (no matter how good). The great thing about using a battery based supply is that it isolates the server's noise (and all MoBos are noisy) from the AC. Prior to using a battery supply, no matter what I did (server powered by linear supply, that linear supply connected to AC line through even a true AC regenerator) I still got noise fed back onto the AC line by the server: All I had to do was monitor noise on the power cable going into my DAC while I booted the server, it was awful.Not all battery supplies are going to be created equal though. You need low impedance for good digital supplies. The only suitable batteries are going to be LiFePO4s, and you are going to want to run them down to only about half capacity before re-charging, so you would need a really big pack to get decent run time. Depending on the voltage range acceptable to the Mini you may also need pre regulation between the battery pack and the Mini. To keep the impedance really low you would want to use a really good discrete regulation circuit (perhaps the AMB), and high capacity battery pack. Also, you would want to keep the regulation circuit as close to the power input pins of the Mini as possible.
