Do note that we cannot offer Cobalt C as level 3 since they are refurbished cores. Only level 2 is offered. For those that needs perfection, please go for nano-crystalline amorphous C cores transformers. Nano-crystalline amorphous C core uses nano-technology and we are proudly saying that it is the best that we got, so far.
Character of the double C Cobalt output transformers:
* Warm and tubey
* Very dense mids / meaty vocals
* Excellent low bass and mid bass focus
* Highs are adequate but not excessive
We got a shock when we replaced the Z11 level 1 with this double C Cobalt output transformers. The 3W does not sound like 3W anymore. It sounded more like a higher power tube amplifier where the grip on the speaker woofer is so tight and taut that it was misunderstood as a high power amplifier.
This Cobalt OPT is suitable for bright, thin sounding or systems that tilt towards the highs. This Cobalt OPT will balance out the sound. In addition, if you are looking for better mid-low bass response for your system, this is the perfect OPT to get.
For balanced sounding system, we recommend the level 3 Precision Wind Z11 and/or PW nano-crystalline C cores. One can choose the Cobalt OPT too if they like warmer sound.
If your room is having mid-low frequency resonances or acoustical issues, this pair of Cobalt OPT will tell you clearly that you have more work to do.
