ohhh yeah. I have/had a stereo pair of:
- 15ips tape saturator mk1
- lotl pentode
- tm79
- ctx transformer mk2
I have a bit of a love/hate relationship with each of them in separately. i got rid of he tm79 because it was more of a distortion unit than color. the pentode is very subtle but has some top end sheen thats very nice. the ctx transformer is tricky, its sweetspot is just before it breaks up but its breakup sounds bad so its better on material with less dynamic range that could stand some warmth. tape saturator is the least subtle with a noticeable low end bump. like @taylor12k said its not “Markus Fischer” tape saturation, much more subtle.
At first i was using only one module at a time. the results were VERY subtle and i considered selling all of them. However lately ive been using all 3 slots at once and bringing in a more noticeable amount of color into the material, this has breathed some new life into the modules.
currently im considering trying out the lotl royal blue as a possible replacement for the ctx. the modules i think helped me uncover very that i dont prefer the “api sound”. maybe ill like the “Neve sound” better?
The lotl modules do seem better designed and higher quality than the diyre ones.
