PrimaLuna DiaLogue Premium EL-34

NEW SET TUBES !!

It's as simple as flipping a switch, and the DiaLogue Premium instantly switches from stereo to monoblock operation! Buy one, and as your budget grows your system can grow too. The benefit of monoblock operation is the amp now has dual output transformers for the best coupling with your speakers, and the addition of a 2-ohm speaker tap added to the 4 and 8-ohm taps. While all PrimaLuna amps are made for ribbons like Magnaplanars and electrostatics like Martin-Logan, you haven't heard anything until you have heard a PrimaLuna monoblock!

Power transformers generate two types of noise, magnetic and acoustic. That's why toroidal power transformers are used in the very best audio products. Compared to standard transformers, toroids radiate about 1/10 the magnetic field that pollutes music and obscures detail. Additionally, the absence of an air gap typically means toroids have an 8:1 reduction of acoustic noise. As transformers are the most expensive components in any audio product, manufacturers will even house cheaper C-core and EI-core transformers in an outboard power supply box with an umbilical cable rather than upgrade to an expensive toroid. The increased cost is significant, but PrimaLuna doesn't cut corners. All PrimaLuna products use massive, potted toroidal transformers. PrimaLuna transformers are enclosed in a metal housing and then potted in a non-microphonic resin to further reduce noise and to protect the windings from moisture and deterioration forever.

Output transformers are the most important part of any tube amp. They determine how low the bass will reach and how high the top end goes. 250 watts of power will have no top and bottom extension if the output transformers don't have the bandwidth. We use lower power to extend tube life, and bandwidth to give you slam. Transformers are the most expensive components in an amplifier, so manufacturers save money by using off the shelf units available on the market. PrimaLuna output transformers are custom-designed, wound in-house, and massive. Our DiaLogue Class components feature the largest, widest-bandwidth output transformers we've ever made. One reason why no other brand sounds like a PrimaLuna. "The flat tops and bottoms of these squarewaves correlate with the amplifier's extended low-frequency response.

With PrimaLuna, you get to choose. Go for it. 6L6G, 6L6GC, 7581A, EL34, EL37, 6550, KT66, KT77, KT88, KT90, KT120, even the monstrous KT150. A future-proof design, PrimaLuna is compatible with NEW tube types not even thought of today!
