Tubed Linestage


I may be upgrading from a ARC PH-3SE to an ARC PH-7. My sound has a bit of an edge to it, which the upgrade may fix. I was wondering about going to a tubed linstage and bypassing my current linestage solid state preamp. I currently have the ARC 3 going into a Theta CB3, then into 2 Krell KMA-160's with a couple of MAXX II's at the end. I read where it was suggested that ARC equipment doesn't mate well with Krell. Any comments or suggestions? I'm looking for a warm, yet clear sound. Oh-I'm using a Clearadio Emotion with a Maestro cart on the front.

Hi...I am surprised to hear that ARC does not mate well with Krell...i have auditioned ARC Ref 3 with Krell at one of the city's top audio dealers...they do it all the time. No problem...sounded great. I have also extensively auditioned Maxx II, krell and ARC Ref 3...i was auditioning the Maxx IIs at the time.

Why are you going ARC 3 into the Theta? i would have suggested that might be the culprit of edge. The ARC Ref 3 straight into the krell into the Maxx IIs should actually be fantastic...
My ARC PH-3SE is a phono stage only. It has to have a linestage preamp. I don't know if the ARC & Krell are a mis-match, just saying that's what I read in a blog here on Audiogon. My thread was a question-not a statement. Has anyone heard of a mismatch between these two, and does the tubed linestage sound like a remedy for my edgyness, or does the proposed PH-7 sound like it may be the fix?
Hi Handyman,

Just a thought. I used to have a ARC PH3-SE for many years. I had it modified by the Great Northern Sound Company and rolled NOS tubes in it. Though improved from stock it always seemed to have a certain "edge" or detail to it as you describe. I believe that the contibutor to that sound was that I left the unit at its stock 47K loading all the time I owned it. I was never proficient enough to solder the supplied resistors in place to change the loading nor did I seek someone out who could. The ARC PH7 has the ability to change the loading to preselected loads from either the remote control or the faceplate.

Only since owning my Nagra phonostage which has the option to change the loading did I hear the difference this can make to the overall musical presentation.

My only regret is that I did not pursue this when I owned the PH3. I believe now this was the source of discontent I heard with this phonostage.

BTW when I auditioned the PH7 against my GNSC Reference modified PH3 with NOS tubes. I consistently preferred the PH7. Tried this two times and reached the same conclusion.
