2a3 or 300b amp for me ?

hi,

Klipsch Cornwalls 101 db eficiency.

should sound great with tube gear of any variety. the cornwalls will sing with any quality design. even higher watt push/pull tube gear is cool

I have been comparing the two tube types on my Lowther Lamhorns, using amps from Electraprint audio, built by Jack Elliano himself, monoblocks, one pr built as 2a3's using nos tubes USN dated 1943, the other pr as 300b's using Sophia mesh Princess tubes(a new pr of Sophia's arrives tonight, having been assured by Sophia that they are an improvement. Listen to classical chamber music only.

The 2a3's are sweet as they could be, particularly great on clarinet and flute, as well as piano. One easily gets to love them. My pair of amps has silver output transformers so these are very quick and transparent, and again, very sweet. Just a real treat and real live beauty.

The 300b's have a wonderful midrange, a fuller lower mid (cello, double bass) and a guttines on all strings that reminds me of live, which is really sometimes even sqeaky, unless Gil Shaham is using his Strad.. If I could pick only one pr to live with forever, would pick the 300b's by a slight margin. Am waiting to see if the new Sophia tubes can sway me even further. also waiting to see how much $ Jack Elliano will charge me for new silver trannies for the 300b's.

Love them both. The tubes you use are critical on both amps, as is the bias. New Sovtek 2a3's are very good, but the nos USN are sweeter. Am collecting a harem of amps, waiting to be able to buy an OTL Tenor pr, so can compare.
Join the search for the Holy Grail and you will always be happy.

Larry, I'm largely with Fjgiovino56 above regarding the general differences between 2a3 & 300b. In my office I have an ASL Orchid 2a3 int amp and at home an Audio Note kit1 300b amp. From extented comparison, I'd say that the above description of 300b sound is what I've found: colorful and full especially in mids and lower mids. The 2a3 is sweet, but doesn't have as strong a charachter as the 300b. The 2a3 seems like it adds less color to the sound and less texture also. Overall, it seems more accurate due to it's clarity and yet gives tremendous depth which is something I always thought was related to a recessed midrange.

That said, I like the sound of my 300b more from a musical pleasure standpoint.

For reference, I haven't tried too many 2a3 tubes: JJ, other Chinese stock, and Sovtek. On the 300b I've tried stock Chinese and western electrics.

You may want to check with Boa2 as he runs Wright 2a3 on his Khorns. His sound is really good and truly satisfying.

Enjoy!
