Hello cmarin,
Congratualtions!
Were the 512Engineering Iso Transformers in use with your Twelve Mk1 dac before?
If not, it's a confounding factor and if feasible, please listen to the Twelve Mk2 again without them and tell us what you think is the diff between Mk1 and Mk2.
Many thanks in advance.
Thank you CK. You’re very kind.
Yes. The transformers had been in place for at least a few weeks with the Mk1 DAC before I sent it to Vincent to be upgraded.
The difference that I heard tonight between the transformers/mk2 combo, and from before with the transformers/mk1 combo was night and day. Part of that difference was clear the first time I turned on the mk2.
However, tonight, after an additional 48 hours of settling in, I was getting layers and layers of additional information than before, in a harmonically coherent and relaxed, non etched or fatiguing, way.
Background material that before was buried in the noise or appeared in the background as one-dimensional silhouettes, is now equally prominent in a palpable, yet coherent, way.
Overall, the mk2/transformers combo has allowed me to get even closer to a real musical experience than I’ve been able to before in my room.
Now, it’s worth noting that this latest experience is only after 48 hours of having turned on the mk2, and late at night when power is cleaner. So I will report back after the mk2 has settled in further and with both day and night listening sessions.
And while the observed positive effect is in part due to the balanced transformers which have themselves lowered the noise floor significantly, the positive difference between the mk2 and mk1 is clear, not insignificant and well worth the incremental value in my opinion.
