Praise for DacMagic


Just wanted to give some very positive feedback for the Cambridge Audio DacMagic DAC. It doesn't seem to get much attention around these forums, but I am enjoying it immensely. In my opion, terrific value for the money.

During the past few weeks, I have used it with great success both within a PC music server and 2-channel environments.

Who knows, I may end up switching it out for a better DAC in the future, but for now I am quite pleased.

As a side note, I was not impressed with it at first when used to enhance an NAD C541 CDP. On a whim, I switched out the NAD for a modest Sony DVD player that is around 5-7 years old. Then, everything came into place and the music was rich and detailed. The Sony DVD/DacMagic combination blew the doors off the NAD/DacMagic combination. Go figure...

Riley804 thought I should include the following to address concerns about messing with power supplies...

A piece of equipment will only draw the power it has been designed to draw - increasing the power rating of the supply will NOT affect this - increasing the voltage will!

e.g. In north america small appliances of different power ratings are all connected to the same power supply - which is generally rated at 15amps - my alarm/radio does not draw 15 amps - probably closer to 0.5 amps, but it is perfectly happy connected to a 15 amp service :-)

Also - if your power supply is rated at 1 amp then you assume that's all it will draw. if it draws more than 1 amp, then the power supply will overheat

Most ratings are continuous, but with hi-fi you have to be able to handle serious peaks in the music and if your power supply cannot do this then you get heat generated, which in turn, causes a whole host of other problems.

All I have done is provide a supply with a higher current rating so the equipment can now handle those peaks - that is all!

Another thing I found is that the CA power supplies were not very accurate - the phono supply measured 16+ volts and the DACMagic measured 14.5 volts

Also - the 22 gauge wire on their supply is no where near large enough to handle the continuous and more importantly peak current draw of this unit!

The new supply I am using measures 13 volts - which is much closer to the 12 volt spec

One thing I have found is that the DACMagic runs considerably cooler with the new power supply - and that is goodness for a unit of this power rating.

Why? - it is likely that the circuit is now getting the current is requires in order to operate as it was designed and is not in a continual state of "stress"

Using an underrated power supply to restrict performance, as appears to be this case, is very dangerous - a fire hazard!

Granted - CA does not want people messing with power supplies...
1. because most people have a complete lack of understanding regarding power ratings - an underrated supply becomes a fire hazard
2. the consequences of putting an incorrect type of supply on equipment would be damaging - The reason for my "WARNING"

They have a blanket policy - Don't mess with our supplies! - it's just so much simpler than an explanation!

What I cannot understand is why CA limits the electronics that has such great potential if properly supplied with power - probably cost related, but could be, they wanted to reign in the performance of this unit so it does not compete with their more expensive line. Guess what - it competes!

This unit is sounding far from stressed right now :-))

BTW - I would caution that you DO NOT try this unless you are adequately experienced - failing to take the proper precautions can lead to equipment failure or worse - FIRE!

Be careful if you are attempting this.

ALSO - because of its size (i.e. Small) connecting the DC Connecter plug required me to insulate the wires inside the plug cover with shrink-sleeve to prevent a short circuit - FATAL!

If you try this - you do so at your own risk!

Electricity is quite simple - unless you cock-it-up!
Wow! That is really fun news and a fun project. What are the model/part numbers of the parts? Any need for soldering? How about peak current? (I have all my audio devices plugged into the same 15A outlet.)
Soundbit - RE: same outlet - there is not problem with this - actually it would be preferable to prevent the dreaded earth loops

There is a taylor made ps from Pangea that is built for this type of upgrade - I would recommend their solution over the DIY one - since they are the pro's

Even at $100 it will make you Dacmagic sing!

Happy listening
UPDATE: another AG member is using a ready made power supply

It's a bit moe expensive, but professionally made by a reputable power company

If I had found out about this I would have gone this route simply because of the hassle soldering the silly little DC connector

I like the look of this unit very much because they have tackled all of the problems and then some including noise filtering - something my solution does not

I would advise going this route

enjoy
It may be that the P100 noise filtering in both directions is a major deal. The "faqs" section for the P100 at Audio Advisor has the best description yet of what the P100 is all about (conversation with the designer), and I just ordered another one for my 640P phono preamp. Hot running "wall wart" power supplies annoy me, but the P100 runs cool and is seemingly a bargain for what it does.
