Why are there two pairs of outputs ? Would there be any advantage for bi-wire here? Is it for a sub? If so - what does that do to the collective load on the amp if you are driving a 4 ohm speaker? I just saw it and started scratching my head. ---

True bi-wire or in my case I use the second pair for the speaker level connection to the subs. ---

Yes - I do the same with my REL subs… ---

I use a quad wire setup, two cables from each binding post. Fantastic that the Amps have 2 sets of posts . ---

Makes sense. I had Martin Logan Odysseys at one point and used to biamp off of a 5 channel amp w them. ---

So how do the bhk 300s compare to the Mac ? If you could elaborate a bit that would be nice. 🙂 Anyone else compare them to some nice gear? ---

I was using an MC302 amp for a couple years before getting the BHK300s. The Mc sounded really good, until I took it to Upscale audio and compared it to the BHK250. The BHK is far superior in dynamics and depth of soundstage. Also just more like you are there. ---

That’s fairly impressive. I have heard the 302 on a pair of b&w 802 d3 and a pair of Sonus Faber Strads. I thought it sounded really good as well. ---

For the speakers we were using, the BHK300’s sounded way more dynamic. In comparison the MC611 monoblocks sounded a bit dull. Could it be the output transformers? I’m not sure. Here’s a recent loudspeaker we listened to, a freshly unboxed pair of Canton Reference 5K’s. Wow, amazing sound with PS Audio gear! Even with a bunch of speakers nearby, bass was deep, tight and quick. Midrange was lifelike and highs were airy. No glare, no harshness, no fatigue. I supposed the Nordost cables helped, too. We just kept the McIntosh amps switched off. ![20190820_210849](https://us1.discourse-cdn.com/flex015/uploads/psaudio/original/3X/2/8/28378b878f5523eef6f93a1ad952e63cf46d2883.jpeg) ![20190820_210735](https://us1.discourse-cdn.com/flex015/uploads/psaudio/original/3X/e/5/e524e342629de4099bd9df0829df70692512dc13.jpeg) ![20190820_211125](https://us1.discourse-cdn.com/flex015/uploads/psaudio/original/3X/9/2/92aa976f2eff86899056690929b0c9ee88a47a70.jpeg) ![20190820_210817](https://us1.discourse-cdn.com/flex015/uploads/psaudio/original/3X/6/6/66ff339baef842944edff5321902ecf539861335.jpeg) ![20190820_211017](https://us1.discourse-cdn.com/flex015/uploads/psaudio/original/3X/d/2/d2537ae0088a20b98b9f279b69843d191c489263.jpeg) ---

Thanks for the kind words, @jamesh. Although I cannot claim credit for buying those components. I merely set them up for a good friend. 🙂 ---

Actually, he let me unbox and break in his pair of BHK300’s. After hearing them, I made the decision to buy my own. Haha… 😄 ---

Beautiful write up. One thing I always hear about the bhk - good bass. I have Maggie 20.7s - so this would be an area where I would want to be sure the amps pushed the bass panels ---

Thanks. @Paul. Under the BHK300’s are a pair of M700. That’s up next. I want to hear the difference. I just wish the BHK preamp had two pairs of XLR outputs instead of just one, and they were switchable from the remote. Perhaps in a future version of the BHK preamp in the P15 chassis? ![20190820_210759](https://us1.discourse-cdn.com/flex015/uploads/psaudio/original/3X/2/2/227aee68408879e0e5f75120c2441e94a9f53513.jpeg)
