Hi all, first post so thanks in advance for your assistance! I'm somewhat of a newbie in the 2 channel HiFi world but have been obsessed with tone and good sound for 25 years. I've been in bands and built an in home music studio where I recorded my band as well as local bands. Music has always been a huge part of my life and it's no surprise that I've found myself obsessed with vinyl and here a SH member. Enough rambling.... let me tell you my current rig and then get to my questions. I have a MoFi Studiodeck with their Master Tracker MM cart, Project s2 phono pre, Denon Al24, Polk PSW 505 subwoofer and Klipsch Heresy IV's. I've ordered a Decware Zen Triode SE341.5 (6 watt) tube amp which I should have in a few months.... after waiting almost a year. I'm highly considering replacing the Polk sub which is currently being "borrowed" from my main TV system for a Rel t/7x. I've got the Polk dialed in just right and it definitely fills out the fq spectrum and adds weight to the music but I can't help but feel it's a home theater sub currently masquerading as a music sub at the moment. I want something faster that will blend in even more seamlessly. As for my questions. My Decware amp only has 1 set of RCA outs. Can I split that signal between an amp and subwoofer? Is there a better option to consider?? Question 2: Should I consider upgrading my phono stage next or linear power supply, inner connects or other? My Project S2 is okay but certainly doesn't give that black background many talk about. With my high efficiency speakers I hear EVERYTHING which can be a blessing and a curse. Love to hear your thoughts. Thanks in advance for all your suggestions and knowledge sharing!
