I'm planning to buy two XPA-1L for my R/L (Vienna Acoustics-Mozart Grand) and go directly from the 105 xlr's into the 1L xlr's for a true fully balanced route (and the hopefully lovely sound of Class A). Anyone here have a feedback on this combo? If you live in Canada I have my XPA-1L's for sale, but if you are in the U.S. it's not cost efficient for me to ship to you. Chad I'm in the U.S., May I ask why you decided to let them go? |

Sound Quality? Well, I don't know if there will be an advantage there...maybe there will...for me it is mainly to keep it clean as possible. Clean? Is that physically clean or sonically clean? There's no real difference physically between XLR and RCA's, however some guys do like the locking feature with XLR connections. Sonically cleaner I'm not a believer, unless you have an EMF noisy environment of course. Yes it should, as long as you are not at the upper or lower limits of adjustment, it will work fine. Well that makes it an easy call then, forget the balanced/non balanced/differential question and move on. Cheers Gary |

Love these amps but they are more suited in a dedicated 2ch system, recently sold my DC-1 as well, the DC-1 and XPA-1L's are very sweet together but I am then constantly disconnecting gear to connect the DC-1 straight to the 1L's, I'm about 50/50 movies and music so just easier to have everything go through the 7030 and XPA-5, and really it sounds great that way for everything anyways. |

Sorry my friend but that just will not do! I do understand you wanting to keep them in the country.
Some one,,,,,,please! buy these quick!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Peace,
Nick

Order been placed. Two XPA-1L, can't wait to taste some of that class A sweetness, will report back...

Chad, As a fellow PT-7030 owner, I am pleased to hear that you thought the 7030/XPA-5 combo was close enough to the dedicated DAC/Monoblock pairing to satisfy you. Order been placed. Two XPA-1L, can't wait to taste some of that class A sweetness, will report back... crimsonpiper, congratulations. We're eager to hear about your impressions of them! |

I run a 105 XLR into a XPA 3 with PHilharmonic 2s...works flawless - good volume about 40-60
I run the RCA inputs into Linkwitz orion / ati...about the same. My ears arent good enough to tell the difference between the 105 direct and a denon 4311 in the middle...ill probably rewire my room to home thru the receiver again soon

Was your friend having a problem? Or did he just want to reduce the lowest volume level? I have the same combo and was considering some attenuators to increase the input impedance of the XPA2 G2 and reduce the lowest volume level. Do you know what attenuators he used and there value? Does anyone know how much the input impedance changes with the different values? I didn't look thru this thread. But I am hoping to hear Kieth's opinion on this. The minimum input impedance Oppo recommends is 47K. James I'm planning to buy two XPA-1L for my R/L (Vienna Acoustics-Mozart Grand) and go directly from the 105 xlr's into the 1L xlr's for a true fully balanced route (and the hopefully lovely sound of Class A). Anyone here have a feedback on this combo? because the low voltage sensitivity of the emotiva amp in relation to the high voltage output of the oppo XLR connectors your gonna need to get XLR in line attenuators for the amp ends. if not, the volume will be too high, possibly speaker damage high. you won't lose resolution, you'll just decrease the voltage of the incoming source to that it's not blasting your speakers out when you go from 0 to 1 on the volume of the 105. i have a 105 and use the dedicated 2 channel out to a UPA-200 with RCA and it's not an issue because of the voltage output of the 105 & the input sensitivity of the amp. this is only an issue when going direct to XLR on an emotiva amp. my friend has a 105 and an XPA-2 gen 2 and had to get the XLR attenuators for the amp end and the problem was resolved and it sounds great! other amps have a high voltage input sensitivity so it's no problem for those amps. good luck and keep us posted. |

Just use a balanced control freak.

Just use a balanced control freak. Boom, Thank you for your reply. I had to look that up. I had no idea what you where talking about. That is a bit more than I would like to spend on an experiment. But do you know how the control freak would affect input impedance? Or how a fixed attenuator say 10db would change t he impedance? Does a 10db attenuator reduce the volume by 10 db? James |

Hi James -
Yes, an "inline attenuator" is a resistor network that reduces the output signal relative to the input. A 10 dB attenuator, in fact, DOES reduce the output by 10 dB relative to the input. They also make 3, 6, and 12 dB attenuators. In my experience, anything over 6 dB makes noticeable differences in the sound. Less is better when using attenuators.
Cheers - Boomzilla

The same can be said for my experience. Though the control freak ( a passive volume control) and the attenuators are both resistors, the control freak should do better. I actually used to reccomend the attenuators because I happened to like the sound change. But switching to a passive pre-amp simply sounded better. Some people feel differently though.
