Z40+ Integrated Amplifier

For those who demand the best, but want to keep things simple. The Z40+ Integrated amplifier delivers the magic, realism, and 3D soundstage of our patented ZOTL technology, all in one (gorgeous) package.

A single-component solution, the Z40+ Integrated amplifier incorporates the acclaimed ZOTL40+ Reference power amplifier, a Berning-designed preamplifier, and LTA’s digital control system–beautifully packaged in a Fern & Roby-designed case.

The  Z40i+ generates up to 51 watts per channel. This means the Z40i+ can easily drive speakers with sensitivity ratings at or above 85db for critical listening. For smaller rooms or non-critical listening, it can drive speakers rated down to 80db. In any configuration, listeners enjoy startling realism, plentiful bass, low noise, plus gorgeous mids and highs.

• LTA’s most powerful, robust sounding amp
• Room-filling soundstage with precise imaging
• Up to 51 watts per channel, perfect for speakers 85dB or above
• KT77 or Premium NOS EL34 output tubes*
• 1  XLR Input, 4 RCA inputs, plus optional phono stage input for turntables
• Subwoofer output
• Optional MM/MC Phono Preamp*

* Note: This listing is for a Z40+ Integrated Amplifier with KT77 tubes and no phono stage. Please contact us if you would like to upgrade to EL34 tubes and/or add a phono stage. Thanks.

Reviews

"Maybe the best integrated amplifier I’ve ever had in my room…Yeah, I think it is the best." ~ Steve Guttenberg

"The LTA Z40+ is a wonderfully appealing package in every way a piece of audio gear should be. It is beautifully designed, a pleasure to use, built around truly original thinking with a decades-long history of David Berning delivering the sonic goods, while offering musical performance that is seamless, rich, and endlessly rewarding." ~ Michael Lavorgna

"The most striking feature of the Z40 is its overall balanced and musically persuasive presentation... This balanced and invariably persuasive presentation offers one extraordinary and rare virtue. The LTA is convincing on all forms of music. It is among the most honest amplifiers I have experienced." ~Enjoy the Music
