New KT150 tubes?

No, I did'nt know it was on and I don't get to the wicked city very often, it's to expensive and time consuming. Did you go? I wonder if they had ARC's new GS amp series there, not that I would be tempted to buy them, I am very happy with my amp.

I do go to Guilford Audios get togethers just south of Reading , when Trevor puts them on and excellent they are.

Hey guys, with your KT150's installed in your REF75 and 150 respectively, was clearance with the cage an issue? Do you have to leave it off. You would not want to "encaged" those beautiful glowing 150's would you??

Me, i have been operating my Classic 120 monos with cage off for years. Not that i have a clearance issue as i use 16 6550 SED Winged C.

I am considering replacing the Classic's with a REF75 or 150. Will likely audition both in my system to see which one can drive my Verity Parsifal Encore most efficiently. My room is fairly large (15.5' x 25' x 7.5'). Would love to audition a REF75 with KT150's but my dealer's demo has the 120's in it. He tells me that the REF75 is sonically superior to the 150 but in my room and with my speakers, the 75 may run out gas at high listening level, hence a 150 being a better fit. Will have to see for myself. He's got 2 used REF150 for sale (customer trade in) that i could get a great price on.

Smoffatt, the ARC Ref 75, you have to leave the cage off, but I agree it is good to see those tubes. I understand this is NOT true of the 150 and other models, the top can stay on.

When I auditioned the Ref 75 with Wilson Duettes, I compared it with the then new VSi75 integrated and a Ref 110, retubed with KT120's. No competition, the 110 was near the 75, but still a clearly audible difference. An experienced reviewer and owner of many ARC amps, commented that the company periodically puts out a barnstorming power amp in the 50 to 100 watt range, one that people remember for decades. He thought the Ref 75 was one of these. Mine certainly is'nt going anywhere. Besides I am retiring next week, I can't afford constant upgrading. I don't know how to improve on the Ref 75, much south of $30000.

Smoffat, I replaced my GNS modified Classic 120s driving Verity Parsifal Ovations with an ARC Ref. 150 about 6 months ago. The amp is tubed with KT 120s. I must say that the improvement was remarkable, with tighter bass, a less colored midrange, and more extended highs. I was unsure before making this change if the Ref. 150 would really make all that much difference but it did. In fact, the improvement in my system by replacing the amps was greater than replacing my GNS modified Ref. 1 preamp with a Ref. 3.
