Title: Dynamo Power supply for Off-Ramp and Synchro-Mesh - now available
Post by: audioengr on 8 Oct 2013, 05:27 pm
This is the new Hynes-based power supply that everyone has been waiting for.  This improves the performance of both Of-Ramp 5 and Synchro-Mesh significantly.  $699.00 plus shipping.  Dynamo can be purchased on the Off-Ramp or Synchro-Mesh pages of the website using the pull-down menu. 

Here are some photos:

Steve,
Can you explain the difference between Hynes supply and the one your mod has?

This uses a slightly larger transformer and the parts are optimized for best performance with Off-Ramp and Synchro-Mesh, including the internal and external wiring/cable. 

It can also easily be changed from 120 to 240VAC by the user.  If the customer later sells or moves to another country this is handy.

Steve, I see it is labelled as 125/250V. Does this mean it can take either voltage?

I see you just answered my question. Great to see you are thinking of the people who move countries.

This might also be a good choice for my 2011 Mac Mini (modded for 12V DC power).  I know Paul Hynes recommends the SR5-12 but one person reported good results with SR3-12 on Pauls forum page.

What do you think Steve?

Its marginal for that load.  I would get the SR5.  I have one coming that could be configured for 12V and shipped directly to you.  email me

Steve -

How big an improvement in SQ does this power supply make with the OR5?
Can you describe in what ways?  I think I'm going to be wanting one.

The Dynamo power supply is now available to order as an option on the Off-Ramp and Synchro-Mesh webpages.  It is $699.00 including the 1 foot cable.

Lead times right now are about 2 weeks.  It weighs 4 pounds and I have not figured out how to do the shipping for an option like this, so if you are ordering one by itself for an upgrade, please email me and I'll quote it with shipping.

Thanks,

Steve N.

Steve,

Since the Offramp 6 will have your new chassis, similar to the Final Drive, will you also redesign the Dynamo Power Supply to match?  If you were not planning on this, obviously with a higher price point, would you be willing to make a custom chassis or a short production run?  By keeping my mate happy with room aesthetics, she is more understanding to my obsession with your products.   :o

Anyone running the Dynamo and Offramp into an Overdrive, I want to hear your impression....

Thanks.

When the OR6 is available, the Dynamo will be available with the new front panel and silver chassis.

Stellar! 

Thank You, Steve.

I would love to hear about the details regarding your pre-amp based on transformers of your final drive.  Will they have balanced inputs and outputs, any options etc.  Would it be best to override the volume control of your Overdrive and use the the line output instead.  Having heard the benefits the Final Drive has to offer, this pre-amp will be a game changer.

Actually, there is nothing to override in the Overdrive.  Nothing in the circuitry changes and nothing is added for the volume control.  It is unlike any other volume control technology.

The Overdrive and Final Drives will still be better than using the Overdrive and the new preamp that I am planning.  Nothing will beat this technology.  Anything else adds noise, distortion and compression.  It is unavoidable.

The goal behind the preamp is to provide an almost equally good preamp/isolation as the Overdrive/Final Drive combination for those that want to use a different DAC.

The planned preamp will have balanced and SE inputs and outputs.  It will be isolated on inputs and outputs and have an internal linear Hynes-type supply for each channel.  The two channels will be completely separate mono preamps, only sharing the AC inlet.

I know this is a stupid question, but does the 1-foot cable length mean that the unit must be within one foot of an outlet?

You can use whatever length AC cord you want.  The DC umbilical is 1 foot to improve transient current capability.

I took delivery of the Dynamo yesterday afternoon for my OR-5.  Right off the bat the sound stage got taller, more detail is unmasked, better transparency and a greater sense of ease.  A more significant improvement than I expected and a great value.  Some of the gains may be due to removing the last wallwart in my AC circuit.  In any case I am very pleased.  Will post impressions again after this thing settles in.

I just took delivery of mine last week.  I am also powering the OR5 and I could not agree more.  The soundstage is wider and soooo much detail with a higher ceiling as well.  Great product that changed the character of my front end/system.  How long are you waiting for it to fully settle-in?

Thanks

Mine arrived today - haven't plugged it in yet.  Waiting for it to un thaw - it was only 25 degrees here today and it felt like an icepack when I opened it.  It sat in a freezer bag for three hours to prevent condensation so I am chomping at the bit to plug it in...

My question - can these be stacked or should it be placed side by side?

Either way.  I usually run it on top so the electric field from the transformer is minimized to the OR.

Received mine yesterday and using it with Synchro Mesh. I run a cd transport into the SM.  Big upgrade in my opinion. Between Steve's cable and the Dynamo I'd say performance of the SM is greatly improved. My digital front end has never sounded better.

Some jitter histograms of an OR5 with OTL mod and Turboclock powered by Dynamo ( S/PDIF output):


(http://www.audiocircle.com/image.php?id=90678)

and powered by the standard wall-wart:


(http://www.audiocircle.com/image.php?id=90679)


As you can see the curve is narrower with the Dynamo.  See the change in vertical scale.  The Dynamo looks the same height, but it isn't.  The vertical scales are different.  I have no control over this scale unfortunately.  The STD deviation is lower in the numbers.

The cool thing about these plots is that the majority of the jitter that repeats and would be audible is in the 10psec range.  Almost as low as the oscillator specs.

Just put the Dynamo power supply into service after first using the Off Ramp 5 with the originally supplied power for four months.  Wow!  Immediate difference for the better.  Very smooth sounding, more inner detail, and pretty much removed the last bit of grain and excessive silibance.  With the Off Ramp 5 HDMI I2S now driving Audio GD Master 7 my setup has never sounded better.  Glad I bit the bullet and ordered the Dynamo supply.  Great upgrade Steve!

Just received the Dynamo and the OTL modded SM. I run it in between a simple Sonos (via SP/dif) and a Bluesound Node (via Toslink) to feed a pair of Goldmund Telos 400 amps with build-in DA converters which in turn power a pair of Leedh E2 speakers and a B&W PVD1 wub. This is simply incredible! Even after just a few hours run-in. With the standard pre-March 2013 SM it was already a great improvement, but this upgrade is HUGE. Especially, the silky details and the lower bass tightness and extension seem again improved (I had to lower the volume of the sub by -2dB - you are not doing any EQ in the SM, right, haha?). Even Spotify can be considered a serious source of music. WoW!

I will also add my endorsement to this great product.  A stunning improvement right out of the box. My system is Mac Mini>OR4 (all options)>Devialet 170>Dynaudio S3.4.   I think I am finally getting close to a digital sound I can live with!

Remove thefuse drawer, pull out the AC selection plug and reverse it so that 230 shows in the little window instead of 110.  Plug the fuse module back in.

Can your new Dynamo/Hynes LPS be converted to 15V 2A for use with my DAC?

No, the Dynamo has a IEC, so you use the AC cable of your choice.  I sell a good shielded rubber AC cable as an option.

The DC cable is 1 foot, but I can make it longer for slightly more.

Unfortunately, I cannot sell the Dynamo except as an option for my products.  It's contractual.
