Tube / SS amp that handles 4ohm loads well and delivers lively texture / palpability


For Triangle signature theta speakers. Real 90db(measured - most manufacturers would claim 94db) Minimum impedance 4.4ohm
amp or integrated. Low volume listening. I would drive an amp with a dac with included class A Ss preamp.

triangles have very sharp high frequencies (horn loaded tweeter) and need a very warm fullbodied amp with texture that manages to be still lively and fast and open.

that screams tube amp but in am concerned about bass performance an coherence as rock solid timing is my goal no.1 and full body my goal no.2 

I thought about el34 amps like lm211ia or class a amps like densen or valvet, class b like LFD.
Small and light gainclones would be nice as well if they can deliver the performance.

I have seen examples of the Music Reference RM-200 offered for around $2000. That's the original version of the amp, not the Mk.2, which goes for around $3000. The RM-200 is an unusual tube amp (bipolar input stage, tube driver and output stages), putting out more power (over 100w/ch) at 4 ohms than at 8. It also has an unusually low output impedance (high damping factor), and produces solid state-tight bass. For details see Michael Fremer's review of both versions on Stereophile's website.

Contact Tommy O’Brien at the Digital Amplifoer Company and explain to him your needs. His class D amps are leaders in their class. Many owners have sold off their expensive class A SET and class A SS in favor of them. I have owned numerous amps of all class types and the DAC amps left them in the dust. 

Clean clear sweet highs, warm involving midrange, deep defined bass, with off the charts detail! All at real world prices! Tommy is a great guy and worth reaching out to.
