Thanks to both. I'm looking long-term for a small, quality tube amp for my new Klipsch. I'm sure either of these would fit-the-bill. I'd lean toward the BAT (is the ARC triode?). Also, I've always wanted the legendary 300B in my system. Currently I'm "House rich" (small "r") so I don't have to worry about it for a while. I remember when $9000 used to be a lot of money.
Additional Audio Research i50 integrated amp info posted by a California retailer. This link includes pictures of the amp. Base model is $5,000 and the model with phono is $5,750. Please see the ad for more details.
Thanks for sharing! I’m partial to the black. I’m curious to hear one and see some detailed reviews. Price point could be ok IMO if the sound holds to traditional ARC standards, I think, but part of me wonders if it’s a little too… gimmicky? The color options remind me a bit of the less expensive Apple IPhones.
I’ve no doubt ARC knows the market better than I do!
5G;'s, not bad.
Jadis jhas a I50 as well, How about that.
2 I50's avalible
Jadis is a bit , well most likely alot more.
But if you have 5G's, you also have 8G's.
My power tube of choice would be the EL34
Pity my Defy will not accept EL34's.
As I say, tube amp = tube amp\Power tube = power tube.
only miniscule differences twix dif labs and dif power tubes.
Blind folded you might/might not tella a kt120 vs a EL34.
I just like the EL34's longer running life, lower price, sweeter midrange vs my KT88's.
The EL34 is and will be the best power tube.
I;'d go Cayin EL34 amps or LM EL34 amps, or Muzishare EL34 amps.
Tube amp = tube amp.
Its all in the craftmanship/quality that sets one apart from the other.
Soundwise, they are all about equal.
Including Dynaco ST90, Allan Organ amps from decdes ago, = both sound just (almost??)as good as the Jadis Defy, with Mundorf top line caps/Takman Metal resistors.
ARC is not going to blow away either of the 3 chinese stars.
Blind test, ,,no wait, even no blind test, you'd be shocked at how close the 3 chinese stars are to Jadis/ARC big guns.
Tube amp = tube amp\
Power tube = power tube.(but each brand does have different voicing, = I found the Gold Lion KT88's not same sound as the Svetlana KT88,,,but I'm thinking the best in this class are the EH KT88's, which is my next purchase)
Myth buster here. and
I toured the ARC facility in Minneapolis end Sept. Commissioner Gordon was the guide. Very top level person. Jaded me was impressed.
We saw a prototype of the I-50. No photos allowed. Comes with auto-bias, hour clock for tube use, choice of 5 colors for trim and optional
Phono stage and/or DAC. This may be for me! I will hear it Oct 27th!
It has more bling than you would expect from ARC.
Same here! I am interested in moving into a tube integrated and really curious as to the sound. Also like that adding the DAC is optional. Pretty great video by Darko that I watched yesterday.- American Made: Audio Research I/50
Happy New Year!
I’m afraid that this post is not going to help anyone too much. First off, I have no experience with equipment of this caliber or any other AR gear. The first couple of weeks, the I/50 was connected to some 20 year-old semi-decent Klipsch speakers and it sounded great (again, to me). My new speakers are not in and the unit has been disconnected during some home construction. During speaker evals at the dealer, I found that the amp is too good for my turntable (Rega P2) and I need to improve my game there.
So- from a guy with tinnitus who ran it for a couple of weeks on bad speakers via an inadequate source- it was lights out awesome.
Big ARC fan here and I like the more contemporary i/50 styling for WAF.
If ARC can deliver its typical product performance in a more contemporary package that perhaps more might want to own, I’m all for that.
A tube integrated amp has been on my bucket list for quite awhile and ARC is always one of my favorite go-tos for reliable tube gear and good sound.
This was taken from the I/50 owners manual.
It seems like the amp can’t be biased by the owner of the amp. If that is true that would definitely be a dealbreaker for me. Just sayin’.
i read somewhere that it has an automatic bias.
@rsfphil i had linked to a preview above that, at the time, said something along the lines of “like all Audio Research’s recent offerings, the I/50 will have auto bias…”. Curiously, the article has been changed and no longer references that. Can’t find it anywhere else either. Huh.
you have it here , and also found it on other site at the time.
@stone1 The amp from Tone is indeed an I/50, but it isn't an ARC I/50. It's from a company in Portugal. The amp from the lbtech link is the ARC I/50 and the article does say auto bias. I think the author may have jumped the gun when he said all ARC amps are auto bias. I read the owners manuals for all of their current amps and it is true that all of the ARC power amps are auto bias, but the two integrated amps aren't. The VSi75 is user adjustable and the I/50 is not. I'm pretty sure if the bias on the I/50 was automatic or user adjustable it would say so in the manual just like it did in all the ARC amp manuals I've read. I guess when you manufacture a product to a certain price point you have to make some compromises.
