the chifi+ss combo also has the advantage of working with low impendence headphones, something the crack can not do. so 80+% over all as good at less then half the cost. they will change your ss amp into a hybrid sound with a lean towards tubey.Įdit2: the combo also costs a lot less then a crack + speedball. you can add some tube magic to anything with them.
My magni has not been hooked up in a while, thats a sys in the shot so i can quick switch between lyr3 and bottlehead.Įdit: those chifi tube amps and pre amps are great. The PC board for the loads on the 6080 tube has very ample heat sinks to assure high reliability.

The 22.1K plate loads of the 12AU7 input triodes are replaced by C4S loads, as are the 3K cathode load resistors of the 6080 triodes.

Speedball is our Camille Cascode Constant Current Source upgrade for the Crack headphone amplifier. The Bottlehead Crack amplifiers arrived a little over two months after having ordered them on Bottlehead’s website. The most hardcore users say it’s a Speedball. they are hooked up to my infinity floorstanders i restored and upgraded with modern drivers. Writing a review after Mike’s interesting and complete 2 page impressions on Facebook isn’t easy, so don’t shoot me if this review turns out short. they are just their for eye candy in that shot to be honest lol. I Love my chifi tube pre-amp and hybrid amp.
the soundstage and presentation and dynamics, most of the techinical stuff, is miles better. can make them sound almost identical with adjusting bass and treble gains on the mini’s. Honestly…i used chifi tube preamp with the jan 5654 tubes, into a chifi hybrid tube amp with same tubes(both the little tube guys).
