Dorado psu

[worrasf]

I posted this review to the other Dorado thread here late last night but on reading this thread I think perhaps it's better posted here. Mods please feel free to delete either of them if considered to be inappropriate double posting.

I fitted the SEG 30 chip today and also installed the Dorado. I now use my “Chinese” 15v LPSU to power the Dorado which then powers the SEG releasing the much better LongDog MCRU 15v LPSU to power the Capella. Prior to the arrival of the Dorado it was the other way around. I left things a few hours to warm up before any listening,

Anyway, despite suffering the tail end of a head cold the improvement the Dorado brings to the table is IMO immense.

Earlier in the day I had a quick listen to Thea Gilmore on CD through amp and speakers. My first thoughts were “clarity”. The music just seems so “clean” with a much larger dynamic range. A bit like back in the day playing the half speed master version of your favourite vinyl album compared to the standard pressing. Simply more of everything and more musical.

Earlier this evening I put a DVD movie through - I had to reduce the volume from my normal position because the bass was so powerful!
I posted this in another "Dorado thread" here yesterday but on reading through this thread I think maybe my review is better here. Mods, feel free to delete either if considered an inappropriate double post.

I’m currently streaming my favourite iPhone playlist so I know it well and listening with Beyer Dynamic DT990 600 ohm headphones (it’s late) driven by the Capella. Not the easiest ‘phones to drive properly. But they have never sounded better. This is what they should sound like but previously have come up a bit short in the all important “foot tapping” area. The dynamics are truly impressive. Bass is incredibly deep and controlled yet the really fine background detail like snare drums or shakers is not drowned out - these aspects of the mix have more clarity than pre-Dorado. There is no over emphasis of any particular instrument or frequency. Tracks I know well sound the best I’ve ever heard on my system. Clearly, some of the improvement listening through the Beyers will be down to the LongDog LPSU replacing the "Chinese" one driving the Capella but I'd heard all of these differences earlier through the Crofts/Epos M22i's.

TBH I am finding it difficult to describe the finer points of the music because I keep getting dragged back to just listening. It’s a big bold statement but the addition of the Dorado really does allow you to just listen to the music and not the kit.

I have no idea what the little box is doing or how it works but at less than £100 including the SEG 30 it’s arguably the best, most cost effective upgrade ever.

I hate repeating myself, but I am having to. The SEG should be used at 15V with the Dorado.
I think that I am going to change the sales option on my site, thereby forcing everyone to buy the optional charger for the Dorado, whether they need it or not. The charger will give you 15V if you don't have a 15V power supply.
The 12V option on the Dorado is for the Bushmaster and the Caiman MKII.
The Dorado has to be plugged in to the DAC directly.

My SEG runs off a 15v LPSU already. I was just wondering if the Dorado had any wider uses or if it should solely be used for the DACs? I have several 12v items I could try it on, but no idea if it would work or provide any benefit. If that's not advisable then I'll stick to using it on the SEG.

Edit: I've quoted the post I was replying to now.

I myself have not tried it with anything other than on the DACs, some phono preamps that I sold, and the Capella HPA. One of the reason for that is that the Dorado is in its Version One state. So it has some safety circuitry that limits the current flow between input and output. That current limiter will trip in if the current load exceeds its set value.
I am however working on some prototypes to extend the principle and get people to try it out in other applications. Best that you email me about this so that I can put your name down as a potential beta tester. As long as you don't double cross me like some did with the Dorado prototype. I hate spending ££££ on research, only to see people copy me to make a quick buck.

I had a look at the order list and couldn't help noticing that some of my sales were going to places where I know specialists take things apart to have a look inside to see how they are made. So expect to see some over engineered copies at hugely inflated prices.

get it copy protected

Anyone with any experience on how the sound changes over time with running in the Dorado? Seems to be a radical change between 5 mins in and 2 hours in.

Thanks Stan, I'll drop you an email. The limits of my DIY skills are plugging a PCI card into a computer, so even switching firmware chips in the SEG is making me slightly nervous. I won't be disassembling anything - at least not deliberately!

Oh goody. They are bound to sound better if they cost a couple of grand

FWIW - it took about 5 minutes for the Dorado to power up to “green led” status on first use yesterday. I turned everything off at the end of the listening session (LSPSU & Dorado). Today, on powering on the LSPSU the Dorado went to green in less than a minute. That suggests to me the Dorado circuit is able to store a huge amount of power for instantaneous delivery. Just saying.

I designed the Dorado in such a way that it stores any unused energy. The energy will dissipate over days. The main reason behind the idea of storing the energy is to improve the speed to get a fully charge state. And that in turn also reduces the carbon footprint.
