"DON ALLEN AMPLIFIERS
I've never heard of these amps, but the same reader who liked the Wavelength Cardinals (in October above), went "crazy" over them. So have a number of other audiophiles who post at Audio Asylum (SET). Here's the letter with some slight editing:
"...the absolute finest amps I've heard recently are being made by Don Allen of Phoenix, Arizona. He makes them all: 45, 1626 Darlings, 2A3, PX25, 300b's, EL 84 all for very reasonable prices ($1700-2000 for a stereo, $2200-2600 for monoblocks!!!). His $1700 2A3 amps blew Gordon's Wavelength Cardinals out of the water!!! Better resolution, better dynamics (yup, that's right!), better frequency extension.
Go to the Audio Asylum's SET page and type in "Don Allen"......see what people are saying. The guy is a genius! His trade mark is a lightening bolt on the front of his amps that is backlit at night! (you can get the amps plain as well....) He uses good stuff (James, Tango, Tamura iron; NOS caps and tubes)...This guy amkes amps that high end manufactureers can only dream about. They're that good."
Personal Notes- I read some of the enthusiastic experiences posted on the SET Asylum, and can verify the reader's observations. The prices appear to be very reasonable to me, with little risk involved. There is no contact information or website URL. To contact Allen, you must make a request to a SET member, such as Todd Kreiger, and he will send you the information directly by e-mail.
I later asked this same reader for more clarification on the Don Allen amplifiers, especially how they compared to the best from Wavelength, and here is his reply to me:
"Are they better than Gordon's? Well.......that's saying a lot if its true. What I will say is that Don Allen amps are sonically just as good, including a comparison to Gordon's Jupiter 50s and 45s which most people feel are Gordon's best amps. BUT remember, Gordon's amps cost 4-10 times the cost of Don Allen's amps! So if considering a cost/performance ratio in any comparison, its not even close!
This isn't my opinion, its the opinion of a growing number of people as you can see on the Audio Asylum. I suggest you contact Todd Krieger, a highly respected Audio Asylum member and audiophile, who has several of Don's amps and knows Don quite well. You can find Todd's moniker (his name) on the Audio Asylum in the SET section.
The nice thing about Don Allen is that he doesn't simply go out and buy super expensive parts and throw them together, claiming to make a world class amp. Instead, he very carefully researches the synergy between a wide variety of components and transformers, usually with the help of 6-8 local audionuts in the Phoenix area. In the process, Don may select less expensive or more esoteric iron and other components, NOT based on price but on performance and design criteria.
Once Don and his band of merrymakers agree that a prototype amp (or preamp or phonostage) has "spoken to God", Don offers the amps to the public. The end products speak for themselves. I'm not 100% sold on his signature "lightening bolts" (he offers amps without them) but I'm willing to look past the bolts and enjoy the music."
Personal Note- I endorse the method Allen uses to design his electronics, particularly his reaching out to the local Phoenix audiophiles for help and confirmation. This is a proven method to get outstanding results and avoid mistakes. The more I hear about Don Allen's amplifiers, the more I am intrigued about them."
