My original setup was Node 2I, Audio Research LS2, Parasound A21 with CW IV tilted in passed listening position. Imaging was not precise, but the sound stage was immersive. It made walls disappeared.
With the addition of Pontus II, CW IV tilted in before listening position, every instrument sounded the way it should, more real, as the band is there in my living room.
Switched to the Willsenton R8 om triode mode, the slight fatigue went away after rolled with many different tubes, 6550, EL34, 6SL7 and 6SN7 of different brands. However, the music does not sound real anymore.
Changed the R8 to Muzishare X9 with 300B, the magic returns. No doubt different tubes yield different sound characteristics, I finally settle with the Linai B300B-H, I forgot to mention somewhere alone added the REL HT-10.
Someone mentioned the CW IV 15-inch woofer is not sufficient for bass. Well, I had similar thought for a while. It all changed after I added the SMSL PL200 into the system. CD are practically collecting dusk. Once a while, the OPPO Blu Ray player used as transport to play some old CD. The new PL200 has no sub out, nor the the Pontus II. I didn't feel anything was missing in the bass region. The CW IV is fast, kick drum, snare drum, different bass nodes are clearly distinguished. The treat off is badly recorded CD will now be more stand out but non musically fatiguing.
BlueSound is great and quick in response to questions. With the mini optical out of the Node 2i to PL200 Optical in and optical out to Pontus II, the REV sub is now also involved. Count this a very happy CW IV customer. Almost forgot to mention CW customer services is also top notch.
