Keep Vintage or sell for new
I have heard both preamps and I came to the conclusion that a recapped FET 10 HL sounded nicer to my ears.   It had a bloom bottom end, rounder, better extended base I imagine to hear from live concerts. The midbass was clearer and more foward t... 
Review: Threshold FET Two sII Preamplifier
I have to agree with MFSLgoldCD. After having had the opportunity to listen to the SP-11 from Audio Research, dozen of Sonic Frontiers preamps, CODA, and PS Audios current model CJ and BHK preamps I came to the following conclusion. The reason th... 
Counterpoint SA-5000 with two monoblocks Threshold SA2e
What I mean is those type of FETs even not selected with their speficially curves are only used in Audio Research amps. You can buy many of the same type and look for one with the same characteristics or buy a second preamp and repair it, but that... 
Counterpoint SA-5000 with two monoblocks Threshold SA2e
Those in the PS would not need matching, but those in the main unit yes as the orginal ones with their matched curves are unavailable. Parts from the middle east need to be matched, otherwise you would not borrow or buy it for a friends unit and u... 
Audible Illusions Modulus 3 Audio Research SP-11
Yup, even the price for the SP-11 is not the issue the availability of the orginal Fets has essentially dried up. Replacement and matching parts come from middle east and their supply is weak and not to mention the parts don’t last as long as the ... 
Audible Illusions Modulus 3 Audio Research SP-11
I had a chance to compare both after hours ( more than 6) of warming up time and my hearing says to go with the Modulus 3!Reason: The Sp-11 has an airy delacy on the top end, but the Modulus 3 is more spacious and liquid and certainly a little mor... 
PS Audio BHK 250 - Is it still a good amp?
I also have doubts about the BHK 250. Having heard about blowing fueses at the RMAF 14 and some owners did have issues with it.I also have doubts about beind stable into 1 ohm or less.Mosfets can be quite fragile at phase angles and so on. However... 
experience with Threshold SA/2e or S/500 amps?
The SA/2e has a better temerature compensation than original SA/2 and a slighty quiter background. I would hesitate if they are faster or not. I do own a SA/2e which is exceedingly rare and I barely hear any difference.It sounds closer to the SA6e... 
RMAF 2019 PS Audio AN3 loudspeaker
Wow, there are too many bad reviews about this speaker around. I can recall a guy in the Audiokarma forum being many times more happy with his Infinity RS2b and another use has a pair of Kappa 9s, bimaped them. 
RMAF 2019 PS Audio AN3 loudspeaker
Lets see where we go. They are available in middle Europe on February 2020 and I will go to a listening session and then report back here. 
Help power pair of Infinity Kappa 9's please
On the other hand for costs you could try two Threshold SA3, Two pairs of Carver Silver 9T's, two Threshold S300 or a Mark Levinson No.23.The best results I have gotten with tube /hybrid preamps. If you cannnot afford expensive ones try Audible Il... 
RMAF 2019 PS Audio AN3 loudspeaker
So in other words compared to older Infinitys such as Kappa 9's, IRS Gammas, IRS Bettas, RS2bs and so on they are not really worth the money or was it the bad sounding room?When I read the comments here I believe nothing has changed since the last... 
Counterpoint SA-5000 with two monoblocks Threshold SA2e
Thats the problem. The industry standard Fets are available, but you need to buy certain quantities to created matched sets.I have found someone who do this too me, but in the case these are also gone, I might consider a SA-5000.Does anyone out th... 
Help power pair of Infinity Kappa 9's please
I agree with George and again to tomlab.The speaker was developed in conjunction with Audio Research M-300 amplfiers.However Arnie used the SP-11 as a pre and various Threshold models to drive them full range.For you info the Adcom wont do the job... 
Help power pair of Infinity Kappa 9's please
I have to add that since some years I tried different combos.If you do not biamp a very high current like the old Threshold SA series is a must. They sounded best at my home with the SA/2 monos.Still the best sweetness and natralness came with an ...
