Looking for an integrated tube amp under $2500
| Post removed |
This afternoon I brought home a Rogue Cronus Magnum 3 from a local dealer to demo over the weekend. After a 1/2 hour warm up, I played the same music I had listened earlier on the BAT. Here are my initial impressions: -the soundstage is bit larger -the music is a bit forward as if I’m sitting a few rows closer -a bit more lush and fuller -bass not as tight but still good -the treble was a bit harsher and not as clear So I checked the tube bias. One tube was at 34mv, the other at 36 so I adjusted both to the correct 35mv. The dealer suggested I try the 4 ohm tap as well as the 8 ohm. I removed the top plate and made the necessary wire adjustments. It sounds better on the 4 ohm tap as it did on the Primaluna. Overall it it sounds a little better especially the treble. I emailed a fellow audiogon member who is selling his Rogue and suggested using a Cifte 12AU7 as the preamp tube. I used Cifte tubes in my PL and thought they were smoother than other various NOS tubes I had tried. So I’m hoping a Cifte or another NOS tube will do the trick. As as someone mentioned above, there is a musical difference between KT120 and EL34 tubes. I did prefer KT77/EL34 type tubes than either KT88 or 120 in my Primaluna. After 45 years it’s like starting all over again, comparing amps and then rolling in different tubes. Tomorrow’s a new day so I’ll start fresh and decide whether it’s worth investing in tubes again or keep the well made and nice sounding BAT amp and call it day. Thanks for all your suggestions and recommendations. |
