I wanted to share two great modifications/tweeks I did to my Rega DAC R. I did two simple modifications that greatly improved, the Rega's already very good sound quality. The two modifications also have the following benefits:

-no special skills or tools are needed to do them;

-they are completely reversible within minutes;

-the two mods cost 134$ Canadian, taxes included.

For a mere 10% increase over the price of the stock Rega DAC R, you will get substantially more than a 10% improvement.

Before I get into the subject and reveal these mods, I will make a few statements. I only make these statements to try and avoid the thread derailing.

I am not affiliated with the companies that make the 2 products. So, I will not defend their technology, their marketing, or the names they choose to name their products. That is completely out of my hands. I will only comment on my experience with these products as used in my Rega DAC R.

My goal is only to share my observations, and let fellow Rega DAC R owners know that they can improve their DAC for very little money and effort. I have done the work, the listening; I have taken the (small) risks involved. If someone else had done the same, I would be very happy to learn from this person.

So, now starts the fun! The 2 mods are:

1. Replace the stock fuse with a Furutech fuse;

2. Put WA Quantum chips (semiconductor type) on the 2 Wolfson DAC ICs, and the XMOS USB receiver IC.

The Furutech fuse

The Furutech fuse renders the Rega DAC R much more transparent and clear. It cleans up the slight grain in the treble. It does all of this without changing the character or flavour of the Rega. It still has all of the Rega qualities: warmth, rhythm, analog sounding. It is much more transparent, but never bright. Imagine Rega made a more expensive DAC with the familiar Rega sound, this is what it would sound like.

I put the fuse in with the F of Furutech towards the fuse holder, and the H of Furutech towards the DAC. It seems to be ideal this way.

The WA Quantum chips

The gains in transparency are surprising. Every instrument and singer is better delineated. The separation between performers is much better. This delineation and separation of instruments and voices was the biggest effect of the chips. The sound is less muddled. It is like turning a lens on a camera and putting an image that was 90% in focus, to 100%. BIG difference.

Another thing that surprised me, was that the chips added a bit of rhythmic snap. I have a Naim 5i integrated amp with the Rega DAC R. So, pace, speed, rhythm and timing (the famous PRAT) was not a weak point of my system. Despite that, the chips gave my system a little more snap and rhythm. All of these benefits came with no loss of speed or dynamics, or dulling of the sound. No tradeoffs!

I was thinking of trying out more expensive DACs. I no longer feel the need. These two tweeks have greatly elevated the sound quality of my Rega DAC R, while keeping its qualities. All for a whopping 134$!

I have included pictures of the chips inside the DAC. It is really easy to take off the cover and install them (just be careful to detach the ground wire).

Is this a joke of some sort? You put stickers on the IC's and the sound changed?!?

I, too, am skeptical of the "chips". But have other people heard of the foil appliques that go on CDs and LPs that are supposed to change the sound? I've tried these, and found no discernible differences. This seems like the same sort of placebo effect... And I think cables do make a difference. Maybe it's just us Newfies though...

It's not a joke, nor the placebo effect.

In the SH forum (my username is Ortorega), I told another Rega DAC R owner about the chips and the fuse. He installed both, and reported back positive sound quality improvements like I did:

http://forums.stevehoffman.tv/threads/r ... on.609610/

I bought the chips from VH Audio:

https://www.vhaudio.com/wa-quantum-chip.html

The owner Chris Venhaus, is a good guy and a straight shooter. He wouldn't sell a product if it didn't work.

A lot of people will convince themselves the chips cannot work and never try them. Their loss...

I took a chance on these chips and I am very happy I did!

Funny you mention this tweak, I placed corn chips on my DAC and the sonic gains were immense! rock music now has much more crunch! :lol:

A visit to the VH Audio site quickly showed that this "quantum chip" product is a scam. The moderators of this forum should ban this OP immediatley.

Unbelievable. Explain how you come to this conclusion that the product is a scam. You are attacking a well known vendor for no reason.

As for demanding that CA ban me; I have been here 11 years. You signed up yesterday just to rant against this product and make accusations.

I know nothing about the vendor but that product is completely fraudulent. There are laws in this country to protect consumers against this type of scam, if anyone has fallen for it they should report it to thier Consumer Affairs office. In the meantime, Canuck Audio Mart should flag fraudsters like this as it gives the entire legitimate industry a bad name.

How do you know the product is fraudulent? Have you tried it? Until you try it, all you have is an uninformed opinion.

You have never posted here before, never contributed, but now you feel compelled to pick a fight over this?!

I take great offense at you calling me a fraudster and publicly asking CA to ban me.

You reported what you heard, no one is being forced to try the tweaks. A ban? :roll:

Talking out of your rear end, like you do is absurd.

You make offensive accusations, and do not bother to explain on what you base your accusations on. You have been rude and disruptive, with no attempt whatsoever to have a civilised conversation about this product.

I only shared my impressions, so that it could benefit people who would like to try these products. No one is forced to do anything. I did not start this thread to engage in mud slinging, with someone who is looking to vent his anger.

I will gladly discuss these products as long as people remain respectful and polite. We don't have to agree, but a minimum of civility and politeness is required.

I have a Rega DAC non R that sounds very good. I even preferred it to the Teddy. Do you think the R is an improvement over the original in sound quality? I am looking for more bass in my all Naim system. Thanks!

I have not compared the Rega DAC R to the non R. Do you use the USB input on your DAC? If so, the asynchronous input on the R is much better.

If not, I can't imagine the R is that much better than the non R. Although, when Toneaudio reviewed the R, they said it was noticeably better.

Look at your room acoustics, speakers, or add a sub if you want to add bass. Changing DACs isn't going to do much.
