PS: Garbulky --- What was the fix for the Axiom prob you mentioned? I'd like to tell you but I would probably be spouting misinformation from a hazy memory. All I remember the problem's went away after some time. Axiom has updated their speaker lines to v3's. Also (and I may be wrong, SO PLEASE NOTE THIS) but Emotiva may have had a fix for it for specific people. But like I said take that with a huge grain of salt in your peanut butter  Honestly contacting Emotiva may help. I think their amps do go into protection when the impedance dips wayy too low where it assumes there is a fault and shuts down to prevent damage to the speakers. With hard clipping it will be obviously audible but not all clipping is audible. BTW, I auditioned some vintage KLH bookshelves. Impressive performes especially as those were the budget line! Got about 85% to 90% of the axiom m80 sound with it not going 100% because of some tizziness in the tweeter and lack of bass extension because of bookshelf size limits. Wish they were still around. I can only imagine what they'd be doing now. |

Well, my 2 cents with using the XPA-2 with my maggie MMG's 86db/w, is that this amp drives the blood thirsty plannars with nary a complaint. To get the LED's to light, at all, I have to be in the mood for some serious volume. I will say, though, I have tripped the protection circuits several times, and I am quite impressed with how quickly they react. One time I touched the amp and I had a huge static shock from my finger. That shut it down. The other time I accidentally shorted the speaker output. Again, small spark and almost immediate shut down.

I now have a dedicated Salamander monoblock stand for my XPA2. Very sexy! :)

David, you have a great 2 channel system! I too have the oppo 105 and love it. Not everyone will agree with me on this forum, but power conditioning, power cords, and speaker cables can bring a tremendous increase in your system's overall performance. That may be the next step for you. Your source, amp and speakers are excellent! Happy listening, and keep us posted on your experiences. |

David, you have a great 2 channel system! I too have the oppo 105 and love it. Not everyone will agree with me on this forum, but power conditioning, power cords, and speaker cables can bring a tremendous increase in your system's overall performance... How curious. I've tried at least a half-dozen power conditioners, multiple power cords including Emotiva's X series and some from Audio Advisor, and I've got a half-dozen speaker cables in house. NONE of these devices has made any significant difference (much less improvement) in my sound. The very few exceptions are discussed below. As for "power conditioners," I've used those from Tippett, Monster Cable, ATC, and PS Audio. I could hear no difference at all with solid state equipment. With a Rogue Audio tube integrated amp, I did find that one Monster power conditioner would cause an audible oscillation (squeal) in one channel of the amp. This never happened with the tube amp plugged directly into the wall. As for "upscale" power cords, I've tried at least four. Other than being stiffer & larger, I could hear no difference. This was true with both 15 and 20 amp connectors. Maybe I was just fortunate in having equipment that didn't skimp on the power cords? Maybe I just have no EMI interference in my listening room? As to speaker wires, my experience has been that shorter ones are better than longer ones (particularly in the bass). This would argue for the "long interconnect plus mono block amps" model, but the difference is very small, and since I now use a subwoofer below 80 Hz., there is no reason to worry about speaker wire length. My experience has also been that the lower the speaker impedance (and the more complex the speaker's crossover), the more I can hear differences in wires. For example, with my old Thiel 3.6 loudspeakers (both low impedance and complicated crossovers), I could clearly hear differences between Nordost Flatwire (lots of screechy treble), Monster Cable (reasonably neutral), and Kimber Kable 8TC (not much treble at all). With higher impedance speakers using simpler crossovers, however, these differences all but disappeared. I also took the time to measure wire impedance. My conclusions indicated that the welded connectors on "Blue Jeans Cable" presented NO measurable difference from the theoretical resistance of clean, bare copper wire. All other wires had measurable added resistance. I now use Blue Jeans and am pleased. Ultimately, though, my experience is the exact opposite of realmaximus's. I do NOT find that power conditioning, power cords, OR speaker cables increase performance significantly. Since I'm sure that Mr. max would not have written that unless he believed it true, you may want to experiment yourself. Consider all my statements prefaced by: "In my room, with my equipment, and to my ears." Cordially - Boomzilla |

At one point I tested every power cord that my local pro audio outlet had with both domestic and professional gear. None of them sounded any different from any of the others. One, which was somewhat undersized, got a bit warm (not hot) running an XPA-2 at party volumes. I too use the shortest speaker cables at home, in a pro environment I have used cables over 200 metres in length without issue, they just need to be the right size and be terminated appropriately. I can't say as I have found much difference between speakers but tube amplifiers in general can be very speaker wire impedance sensitive, especially those with transformer coupling. I make my own speaker cables, crimp and solder. Ditto As usual, the same applies to my views. Cheers Gary |

Mr. Cook, you're a gentleman & a scholar! (despite the fact that you're foolish enough to agree with me) LOL
