Just took delivery of this headphone amp. Pics
After reading great reviews, I decided to give it a try when I found a killer price for a new unit. I am pairing it with my Denon AH-D7000. I will report back with my findings. Stay tuned.
tech specs: The Bellari HA540 is Built Right Here In the USA! The Bellari HA540 was built for those of us who have lusted after tube headphone amplifiers only to be dismayed at the enormous expense. The HA540 is an honest to goodness zero feedback Class-A, all tube headphone amplifier in a very compact chassis. How good can it be at this price? Excellent, actually! Just like Bellari's outstanding phono preamps, the HA540 offers an extremely detailed, rich, bold sound with a surprisingly reasonable price. The HA540 is a very flexible design with a lot of great features that should be standard on every headphone amp. The first great feature is the visible 12AX7 tube! This gorgeous, capable amp drives headphones from 16-2k Ohms and offers both 1/4" and 1/8" outputs. Input selection is also quite extensive, with both an RCA and a Mini-Jack input (selectable). The HA540 is also designed to extract maximum performance from any source with two types of inputs to match any source. We love the sound from this all-tube headphone amp, and we know you will, too! Two Types of Inputs To ensure the best sound possible from any source, the HA540 has two different input types, Low and High. High is for devices with robust output stages like full-size CD players, tape outputs from a preamp or receiver etc. Low is a special input which offers greater gain for portable devices or any device that doesn't have a robust output stage. Why is this necessary? Imagine the HA540 sitting on your desk at work. The High input is connected to your high-quality USB DAC and the Low input is connected to your iPod, XM Radio tuner or portable radio. The two types of inputs can be selected from a top panel selector. Specifications Input Impedance: 47k ohms Output Impedance: 16 ohms Max Output Level: +15dBv @ 1kHz at .1% dist. THD: 0.05% @ 1KHz S/N Ratio: >80 dB unweighted Power Indicator: 1x LED Max Output Power: up to 500 mW/side, 1W/Stereo ( @ 16 Ohms ) Frequency Response: 5 Hz - 30 kHz Phase Shift (In to Out): 0 db Crosstalk: - 75 dB Headphone impedance: 16 Ohms to 2000 Ohms Max Input Level: +15 dBV Input Connectors: LOW *: RCA (Pr) & 1/8" (3.5mm)Stereo HIGH: RCA (Pr) Outputs: 1x 1/4" Stereo jack 1x 1/8" (3.5 mm) Stereo jack Power: 15 VDC @ 700mA Dimensions(HWD): 2.5x6x5.4" Weight: 2 Lbs *NOTE: There are two Low connection options, Mini-Jack and RCA. This allows either a Mini to Mini or a Mini to RCA cable to be used. These are either/or inputs, please don't use them simultaneously.

Is it quiet? I had a Bellari phono stage I used to get going with vinyl. It was very musical but there was one drawback. Certain times of day and some evenings I would get a Spanish language radio station bleeding in over the speakers. Now, it wouldn't be so bad if I knew what the hell they were saying....

So far, no noise of any kind. One thing I did was change the Ruby tube to a new Mullard 12AX7. The Ruby was too soft for my taste. I have a McIntosh stock 12AX7 and a JJ Gold Pins to try too. The Mullard sounds 10x better than the Ruby. Tighter bass and more balanced sound.
I'm gonna burn it for a few days before I do some serious listening.
