XPA-1: "Fully balanced, quad differential input stage, with cross coupled active current sources." Re: Emotiva XPA-200 - What can we expect? « Reply #23 on Jun 2, 2012, 7:24am » "Hi guys, The XPA-1 is the only Differential Reference amplifier in the line for now. It is designed to complement our other Differential Reference components, such as the ERC-2, the the XSP-1,etc. All of these components features truly balanced circuit topologies (not just balanced connectors). We are working on a baby brother for the XPA-1 but it's not something to think about until next year. Now as far as lines are concerned, the XPA Series is not being replaced by the XPR series. They are two distinct lines. X is our core line. This is the heart and soul of Emotiva. It will also be our largest line of products. Ultra is our value line, designed to bring high performance audio to you at prices that make great sound affordable to anyone. X Reference is our "no holds barred line", and as a general rule, it will all also feature very high power amplifiers! (You can never have too much power) It is the designed to be the biggest and the baddest. We'll put XPR up against anything out there. There are no plans at present for an XPA-700, however we are working on an new XPA-7, as has been previously noted elsewhere. Hope this helps, Cheers, Dan" I guess I don't know enough about what's differential. I had no idea there was a dual differential and quad differential or what any of that means. Pay no mind to me Jerry

jamrock, Nobody "need" an amp like the XPR-5.... In reference to your comment...I would say that all we need is food, water, clothes, and shelter...you know how it is...lets let people enjoy the luxury's in life...who needs a yacht, not me, but boy I would like to have one..., I would also say the same about the XPR-5...it is a luxury that some people just got to have, if you know what I mean. +1 For the first time, Emotiva has a truly luxurious feel good product with the XPR-5. Just look at it! I love my XPA-1's and what they do, but every time I push that plastic button to power it on, a little voice says: "budget!"... It doesn't matter the XPR-5 is five times cheaper than a Classé 5ch amp, it makes just as much (if not more) appeal to me Have I mentioned I want one? I think I will tuck all other gear behind a acid-glass door so the beast can attract all the looks it deserves.

I would like to see Emo provide just a simplified block diagram for both the XPA-1 and the XPA-2 from input to output. I think that would clear a lot up for folks if they could just see the block diagrams. BTW, I'm a retired Air Force guy.-- Worked on electronic warfare equipment to include radar transmitters (jammers) and radar warning receivers on the F4-E fighter aircraft and in the backshop. After the F4s were transferred to the guard, I retrained into backshop F-15 Integrated Avionics. I'm by no means an engineer but I've used an o'scope, spectrum analyzer, signal generator, and multimeter a few times....

Learned that from my High School electronics/electrical teacher way back in 1969!!

Learned that from my High School electronics/electrical teacher way back in 1969!! I learned it too in basic electronics school in the 1980s, Keesler Air Force Base, Mississipi through a civilian instructor. Teach it now in this day and age-- You'd probably be-- FIRED!

During the Vietnam War I worked for a defense contractor modifying F-4 fighter planes with terrain following radar, jamming and detection avionics. That was my introduction to highly sophisticated electronics and testing equipment. It required obtaining Top Secret security clearance and working within a fenced hangar with guard towers all around the planes with armed guards watching every move you made. That took a while to get used to. Just imagine you and I may have worked on the same electronics in the same F-4s four-plus decades ago. It's a small world.

RR:
My First duty station after tech school was Goldsboro, N.C. Seymour Johnson AFB, 1982-1993.
I worked on the F4-E fighter aircraft and in the backshop on the AN/ALR-46 radar warning receiver, AN/ALE Chaff/Flare Dispenser, and the AN/ALQ-131 radar jamming pod, a 3 band 650 lb transmitter.
When Big Dan says:
"You can't fool it, even with high frequency transients, as its switching time is faster than the rise time of a 20kHz signal. Sweet!"
I at least have a clue on what he is talking about...

Is it just me or wasn't the XPR-5 priced at $1709 for the past few days? The product page has it as $1,799.10 now (which is indeed 10% off, but I could of sworn it was $1709 previously.)

Nope, it was 1,799, down from 1,999.
