Preamp connection to multiple powered subwoofers
Got it. The comment about putting the crossover ‘behind’ the preamp threw me off a bit. What you described is more like the ‘front’ of the preamp. But, I might be overthinking it again 😎 
Preamp connection to multiple powered subwoofers
Not sure if I quite follow the crossover arrangement but the use of a buffer such as iFi micro iTube2 seems quite logical, especially with its 1M ohm input impedance and ~150 ohm output impedance in direct buffer mode. I’ll probably start with a t... 
Preamp connection to multiple powered subwoofers
"...get a high input impedance buffer and put it between your pre and subs. It works great fo me."Can you recommend a specific brand/model? If at all possible, I much prefer having the ability to use the RCA outputs since it potentially allows for...

"...did I not already say don’t overthink it?"Yes sir, you did. Guilty as charged. I appreciate your input based on your practical experience.   
Preamp connection to multiple powered subwoofers
Thank you. Those impedance values pretty much rule out the use of the second (parallel) output from the Unlimited to drive all the powered subwoofers. I also remember reading somewhere that selecting too large uF output coupling capacitors can hav... 
Preamp connection to multiple powered subwoofers
Thank you all, particularly Al for his detailed response, as always. Assuming a 10K input impedance for the sub plate amplifiers, the combined impedance will be about 2,500 ohms which is technically too low even for the (published) 600 ohm output ... 
Preamp connection to multiple powered subwoofers
Thank you guys, appreciate it. I can see how I could use a couple of splitters off the second pair of RCA outputs and run the four (powered) subs in mono. Makes sense. And perhaps I'm overthinking the impedance matching side of it but I was just c... 
Preamp Output Capacitor: Mundorf Supreme vs. Supreme Silver Oil
This thread is extremely educational but at the risk of sounding a bit nerdy, I just want to say that these sort of “tweaks” should be handled with extreme care and sometimes best left to qualified techs and/or experienced DIY folks. Almost all th... 
Aric Audio Systems Unlimited Preamp
By the way, I must mention that the quality of the phono stage in the Unlimited is also pretty decent. Anyone considering using a turntable may want to opt for low(er) noise (and/or lower gain) tubes depending on the cartridge used.The linestage i...

Here are a couple of comparisons/reviews for the new stock 12AX7 tubes:https://www.thetubestore.com/12ax7-tube-reviewshttps://www.tubesandmore.com/tech-corner/12ax7-comparison-current-made-tubes 
Need help with speaker wire connection to ARC Classic 60
I’ve been using what inhifiman suggested with banana plugs in my old McIntosh amplifier for several years with no issues. I do remove them every now and then and clean them with alcohol just to keep the contacts clean. They work very well. 
Aric Audio? First Watt? PrimaLuna?
"My "listening room" is my garage, unheated and uncooled..."Out of curiosity, is this garage dedicated/converted to a listening room, e.g., furniture, room treatment, etc., or is a "multi-purpose" garage with car(s) and also used for music listeni... 
Aric Audio Systems Unlimited Preamp
In my experience, the "flavor" that different signal tubes add/subtract to/from the music and whether or not you ultimately prefer the sound, will depend on the gear upstream and downstream from the Unlimited, maybe even the cables. I have tried J... 
MHDT Orchid or Lampizator Amber 3?
Congratulations indeed. You got yourself a great DAC. Enjoy.   
Room Correction without loosing MQA and DSD
Your current Orchid DAC is neither MQA-enabled nor outputs anything higher than 16/44.1. Are you only looking for something with a built in DAC?
