Member's recommendations for tube amplification

David,  glad that was helpful.  This is the same amp Berning uses (in the 6B4G configuration) in this personal system . . . and he is driving 87db speakers. The reason these are "affordable" is because he builds them in his own shop, cosmetics be damned (although there is relatively inexpensive solution to the cosmetics)!!   I have had for years the flagship integrated of Pathos Acoustics - the Inpol2, which is a hybrid design with tube input and MOSFET outputs, fully balanced, 45W Class A.  A new one will cost you $13k. I've got mine listed for $4K.  Its a wonderful amp, but the Berning is significantly better.

Best of luck in your search!

@rmasoni Rick, interestingly I clicked on one of the Agon ads...for the Voxativ Zeth speaker and one of the ’blurbs’ from a show mention the 6B4G driving these speakers.

@rspyder Ray, I came close to buying an Octave integrated amplifier a number of years ago...ended up going with an Ayon. Another German player, Lyric is newer to the U.S. Any thoughts?

I’ve been focused on an amp and did not specify an integrated as an option in my opening post. I already have nearly 40 recommendations!

Do you and others feel / believe I should be open to a tube integrated amplifier?

Pros/ Cons? Thanks.

You might look at the Line Magnetic 508IA, SET, Pure Class A, 48 watts per channel. Here is a link to a site that says a little about it.

There is a dealer called GoldPrint Audio that you can contact if you wish. I think that they still sell them.

Audiogon member Waltersalas uses the Line Magnetic 508ia with his Double Impacts and says the results are stunning.  No shortage of exceptional amplifier options for this speaker.

Coincident Frankenstein MkII - very good sound in all parameters. The manufacturer is not the best to deal with, but sound quality here I must say is of the highest note. You can still improve by asking for caps upgrade before ordering. It drives 89dB speakers to quite nice levels, but I wouldn't use them with large drivers, 10inch max. With bigger ones, it lacks attack and dynamics. Depending on your speaker character, you can play with 300B tubes, the WE300B replica from Psvane is marvelous, and gives incredible details and mids. The Takatsuki TA300B is slightly more balanced (again, will depend on speaker and/or your taste) and gives better bass. The Psvane black bottle does very well too. A good preamp will obviously improve these SET quite dramatically. Although I usually prefer to pair transistor/tube preamp/amps, I have experienced that they match perfectly with their cousin, the Coincident Statement Line.
