Tekton Double Impacts

I’d seriously consider a used First Watt amplifier as a viable alternative if you’re adamant about only seeking a transistor amplifier. Nelson Pass design pure class A and ultra simple circuit. It has enough power for the Double Impacts.

I think that in terms of musicality  and natural high quality sound presentation  it may be superior to the other candidates mentioned, just my humble opinion.
Good luck ,,

bullitt, what preamp will you be using?

I would 2nd the first watt as a very good choice,I have owned and or heard everyone of the except the sit 1 mono blocks.You might look for the J2,F3 and the F7 I think these would be outstanding driving the DI's.

I presently own a diy push pull sit that uses nos Sony Vfet's and I have a F7,but I haven't used it with the DI's yet.Maybe this week I will try it with my LTA MZ2 preamp.

One thing to consider is the first watt amps will hold their value better than most others.

Best of luck to you,

Kenny.

Kenny, I was interested in the reworking of your DI's.  In particular how you changed your woofers from the alphas to the betas.  On paper these are two different drivers.  I could see how the betas with their larger magnets might offer slightly more efficiency and tighter bass, but at the expense  of low end extension. The betas do have a slightly higher Fs as expected.
On a somewhat related note, how do these drivers achieve such low end extension when their resonant frequencies are in the low 50's?? They obviously extend well beyond that but I always read that Fs defines the low end extension and even in a reflex enclosure this seems way deeper than I would expect.  Any thoughts?

Bullitt--in addition to Corelli's question, what source will you be using and do you intend to run the DIs with the separate/new amp as part of a multi-channel?  You mentioned going to Atmos.  Which will be your priority--stereo or HT?

I've had three emotiva amps and still have two.  They generally reside in a 7.1 HT.  I think they are good amps for the money, new, and offer a good power-to-money value.  Mine are quiet as a tomb and are detailed well above their price.  But, I personally find them to be pretty cold and clinical and a touch artificial.  Add to fatigue factor, but responsive enough to upstream changes to be tamable.  A lot of folks like that type of sound and don't perceive it to be cold or artificial.  Emotiva has served as a gateway drug for many.

If music/stereo is the priority, even 50/50, I'd go in the same general direction as Charles suggested.  $1500, especially if you consider used,, gives you lots of options, including tube and hybrid.
