Modding the DirectStream DAC MKI

Thanks Ted!

Letting all this happen (even for a not yet released product) and even supporting it to a meaningful degree, for me is the single best act for the community and shows great transparency and openness of Paul and Ted. I continue to be really impressed!

I have rewired a pair of 4400 transformers to give +6dB more gain. Works great and sounds more dynamic. It doesn’t sound as good as the premium transformers however they cost way less.

No news from the owners of lundahl?

They just arrived, I guess it will take another 6-12 weeks until I’d have the DS forth and back from modding. Before they are soldered in I have to get the transformers tuned at a different place like the whole rest of the DAC. And if I also want to fully search/understand the recommended cap mod for implementation (not to speak of the VOCM thing, which probably is too complicated to even tell a modder with clear recommendations out of the thread), I guess it will rather take the 12 weeks.

I also have it out currently for a completely different improved tuning, which I want to check for the result first, to not confuse effects.

Let’s see if the Airlens shows up on the horizon in the meantime, then there’s another improvement coming. Something going on on my digital side in the next months :wink:

Hi Ted,
I understand that the transformer configuration (serie or parallel) has no problem with my Spectral’s (preamp) 10K low input resistance.
I would think to keep the output impedance of the DS as low as possible for the best result.

Received the Lundahlā€˜s from a European distributor. Installation with jkrichardā€˜s adaptors was flawless. All I could do was a short test run. Everything works as expected. I am a little busy these days but will report later.

Unfortunately I had a problem paying with credit card to purchase lundahl on audiohobby site. I tried 3 different cards of 3 different banks and the result is negative.

It’s a good thing they are indestructible and I wrapped them in the 2 page manual.
Looks like they pull it from the engine compartment.

I personally just don’t have much respect or trust for the USPS anymore :frowning: YMMV. T

I was a bit nervous when I unpacked the package today.
And there are some problems.
I will send you a message.

I solved the Lundahl intake problem.
I’m waiting.
Photo or video for montage would be greatly appreciated at this stage.
I’m afraid of making mistakes.
