Sorry for late return message
Pass and CJ use single ended IC cables
Pass pre and pass amp was very detailed
The CJ tubed pre and my predominant music of rock era “ took the edge “ off crappy recordings and really was best of both worlds : tube & SS
The stock CJ tube was sharp and detailed . I change to a Mitsubishi 7dj8 and the lush English gentleman sound of preamps was presented
The 25 db of gain vs most other 8 db gives you a lot of flexibility with sound levels with the lower powered xa30.5
