    Got a chance to upgrade my pre & amp(s)

    Moving from ARC SP17 to ARC REF 3

    Also moving on from 2x Linn LK100 to single Krell KSA 150

    Anyone running ARC tubes with Krell SS?

    So...you just HAVE a chance? Or you're going to TAKE the chance?
    - Is your air conditioning up to snuff to handle 300+ watts of Class A space heater?

    My hat's off to you, running tubes in a loft in Chapel Hill! You are a much better audiophile than I, who ruled out a Pass Labs amp because the heat bothered me -- in Portland, where humidity is a concept, not a reality.

    Close... I ran a Mac tube pre with a KSA 250 with great results. Even with a SS Pre, the Krell was a pleasure to listen to.

    fwiw... the KSA 250 was the best ss amp I ever heard up to my Pass amps now. I didn't like Krell's next few generations as much. I bet you will really like the KSA 150.

    Yes, I know. We lived in Beaufort, NC -- about 4 hours SE of you -- for 11 years. It was so humid, we had to install dehumidifiers in our crawl space.

    Nice choice on the Ref 3, but then again I'm a little biased! I'm pretty sure you'll like it, a lot!

    I ran my Ref 3 for a short while with my Krell 402e and was really quite impressed. Had Totem Mani2s at the time. There was a sense of reality that I really liked. The detail and resolution, especially for low-mid (think cello) or some big fat analogue synth was astonishing. Vocals were amazing too. It was a great pairing, but not destined to last long. I ended up buying a Ref75SE to go with the Ref3 (and Ref2 Phone SE) for that system. I didn't plan to buy essentially an all ARC system, sometimes things just work out that way.

    Has the KSA-150 been recapped recently? How old is it? Is it gonna get hot, yeah, but hey, it's a dry heat ;)

    Envious of the all ARC setup!

    The KSA-150 is on it's second owner. It has been serviced and recapped by Krell within the past 5 years.

    I lived in the Triangle for years before moving to St. Louis. I'd rather be there in the summer than St.Louis. humidity is worse here.

    Sure miss A Southern Seasons.

    I used to own a KSA-150. Biggest problem you’ll have with it is getting it up those stairs!

    Yes I loved going into the store. It hurt when they closed it. Best coffee selection I ever seen and had...real premium coffee. I'm just grateful you can still order their products on line. I can still get the coffee as well as a few other items.

    Update: The REF3 and the KSA 150 have been added to my setup. The REF3 came with 10K+ tube hours so I've immediately swapped those out for new Sovtek 6H30's & Tung-Sol 6550. There's also an audible idle hum from the amp - guessing the caps need to be replaced. Other than that, the tube break in is revealing a level of clarity and soundstage I've yet to experience in my personal setup. Very pleased.

    Heavy but good news. Sounds like a great combo

    Yeah, I had a KSA 150 with a CAT tube preamp. Sounded great. I later went with a pair of CAT mono's that weighed in at 180 lbs. each. The Krell was nothing compared to those things. I carried my Krell up three flights of stairs, and it was not fun.

    Listen with the preamp disconnected to see if you still hear any hum. It might be from the pre. You definitely need to check to be sure the small caps on the boards have been replaced. The large filter caps are usually fine.

    Thanks Bill - yes, I isolated the amp and the hum was still there. Doesn't really effect playback, but it is certainly annoying at low volume and idle.

    Amps don't normally have much ground hum on their own, so it is most likely in need of a recap. These run hot, so that puts a lot of stress on their lifespan.

    I don’t have one of the legendary Krell amps but my amp definitely raised my system’s reproduction of the musical experience by several levels. Visitors always comment on the speakers the amps are not getting the credit they deserve. one day I’d like to switch in a tube pre-amp just to see what it can do.
