Hello Duke,
I really appreciate the sharing of your really insightful and very detailed experiences with external PSUs. There is also a point that a 1000,- PSU to support a sub 2000,- product might be a bit out of proportion.
As I am also rather sceptical about the use of a laptop charger for powering an amp and your story really made sense to me, I ordered one of these HDPLEX PSUs as well. I am pretty certain it will make a difference.
Appreciate you jumping in to help out.
Regards,
Kuoppis
Hi Kuoppis,
No problem, I am happy to help. My typing speed is very slow and I am not on HeadFi often (I mainly just private PM with a guy from Texas who I highly respect).
So, I mainly use HeadFi for research, though I thought this question about external PSU's was something I could actually contribute back to the community and maybe help someone else.
After all I did nearly an hour of research per day over 3 months, close to 100 hours , starting back all the way in August (1 hour per day reading on my iPad while on the exercise bike).
Yes, I too was sceptical about the laptop charger ... when I read the 6Moons review and saw it was a Toshiba laptop charger, I then checked out the charger on Amazon, they cost $9.50.
In the same 6Moons review, they actually state that the packaging for the Gemini costs $10.
So effectively more is spent on the packaging than the supplied laptop charger.
The Chris Martens review was also influential in my purchase of the Gemini 2000 ... so that set the seed of the idea of getting an external Regulated Linear PSU to see if that would further optimize the Gemini that I was planning to get.
Also, I have noticed a trend, especially over the last 2 years, about what I call the "Rise of the Linear PSU".
Everyone from SBT users, to people making CAPS music servers (over on Computer Audiophile), to the guys on the JPlay forums (those guys are extreme, really pushing the edge),
are reporting benefits from using Linear PSU's.
Previously I plugged my DACmini CX into an XPAL 18000 LiPo battery I had spare and heard an improvement, so I thought why not give
Linear PSU's a go.
Before I pressed send on that post, I did hesitate for a moment in case I sounded like a shill for HD-Plex, or just too hype'ing a product too much ... then thought stuff it, I had a great experience with them, why not share it.
I also hope I have not over-hyped it over the top and "Set expectations" too high. Still it remains a much better tweak than HP cables or other cable tweaks have proved... I actually once spent more on a reference HP cable than what I spent on the PSU ... I struggled to hear the improvement with the aftermarket cable (it was their, but mainly for critical listening), though the PSU was immediate and welcome in it's improvements.
RE "I see you are going a step further, I do not have a dedicated line, as there are no big factories in the immediate vicinity. But I am sometimes wondering how some of the hi- end gear is supposed to sound, as they are typically supplied with an inferior power setup while so much can be achieved when optimizing it a bit."
I wonder the exact same thing about how much the true potential of gear is limited by using inferior power supplies.
If you look at a manufacturer's range of product, their reference product always has the very best power supply ... sometimes even in an external case.
RE "I ordered one of these HDPLEX PSUs as well."
Great to hear. It is pretty simple to setup. Just
1) select the correct input voltage for your country on the back of the HD-Plex (their is red switch on the back)
2) plug the XLR-to-DC power cable , XLR plug to the 19V output ... DC plug to the Gemini
3) power the gear on
Child's play to setup.
The only issue I had was that the stock XLR-to DC power cable seemed to have a 2.1mm DC plug (which did not fit the input of the Gemini ... the DC input of the Gemini is 2.5mm).
I was glad that I asked Larry from HD-Plex for an additional XLR-to-DC power cable, specifically with a 2.5mm DC plug when I placed the order.
As mentioned before, that cable arrived the next day and worked fine (into the back of the Gemini).
As an aside ... Magico speakers ??? Man, you are playing at a level above us mere mortals
Another aside ... I wonder if the Gemini would be taken more seriously if Auralic offered a version without the Klutz headphone stand integrated into the unit.
That is , just the base part that contains the DAC/AMP section, without the headphone stand part.
If they did that (and reduced the price accordingly) they may reach a larger audience.
Also, now that I actually have the Gemini I really do appreciate the headphone stand part ... though initially it was a bit of a negative on first looks ... I thought how much is spent on the stand part in comparison to the DAC/AMP part.
Anyway, that is enough typing from me for now. Silly season (xmas party's) is now in full swing.
