With the balanced inputs the Taboo MK4 also has the option of being used single ended. I too opted for the balanced option simply to use minimal chain from my DAC to the amp as an option I don’t have available to me with some of my other amplifiers.
I have an older CSP2 pre-amp/HP amp that I have used in the past as a pre-amp and I love it’s ability to fine tune the voltage input into my amp per channel individually.
I have mated my Decware CSP2 to an older Sugden FP-4 class A and the combo had authoritative and impressive synergy, more so than with other pre-amps I have tried.
I also flat out enjoy the CSP2 with a variety of HP’s, ie Grado, ZMF, ATH, Senn, Kennerton.
The older Taboo amplifiers were reviewed extensively by folks over on the “bigger” forums years past along with the CSP2’s and overall had positive reviews but just like many a product fell out of favor due to the regular influx of newer “shinier” equipment that hit the market. The Decware products are dated a bit BUT Every few years have had small modifications and upgrades engineered into them that have kept them relevant and marketable. They are not for everyone, but for those of us looking for a particular quality and the ability to fine tune via tube rolling, they continue to be a very viable and relevant product.
I genuinely dislike hyping a product or even making recommendations because folks will pick it apart, form an opinion early on and then move on, leaving a distaste in my mouth that I find annoying and objectionable. I tend to hold onto products, continually mate them and experiment with various others and look for synergistic matches which I can enjoy.
Decware is a small boutique manufacturer, they are OK, wait till next year and I’m sure plenty of their units will show up on the used market. Shoo, nothing to see here stop hogging up their queue with orders, that’s just delaying my own current order and depleting their inventory of parts…go look at Quicksilver and Felix audio shoo I say🤡
Happy listening always.
BTW, don’t look at the “Rachel” 341.5 amp with the HP option or mated off the speaker taps…shoo I say shoo…look elsewhere.
