no longer for sale

We are now offering an Underwood Hifi modified LSA Standard integrated amplifier. The LSA Standard is a high quality 150 watts per channel remote controlled hybrid integrated amp with a tube preamp driving a hi-current solid state power amplifier.

In the Stereophile review they said the Standard is:
", uncolored and captivating... silky and organic..."
Robert J. Reina, Stereophile, June 2006

Other review quotes are as follows:
"...very rugged and sexy-looking amplifier..."

"...The large, sleek, visually stunning [amp] features a tube line stage with 6922 triodes and partially dual-mono amplifier circuitry with Solen output devices..."

"...The midrange qualities indicated that the integrated amp possessed some of the hallmark attributes of a high-quality tube preamp. Every vocal recording I tried with the [amp] was silky, rich, uncolored, and captivating..."

" notes read 'angelic holographic blended harmonies.' Male vocals were equally enticing. Mighty Sam McClain's warm, gutteral growl was silky and organic..."

"...tremendous low-end slam, and its reproduction seemed effortless even at high volumes..."

"...lightning-fast ability to render rapid transients without any sence of blunting or artificial edge..."

'''My listening note: 'Chills!' "

The Standard uses advanced vacuum tube circuitry in the pre-amp section (6922 tubes) and twin toroidal solid-state transformers. It is rated at 150 watts per channel and typically puts out over 180 watts. It doubles to over 300 watts into 4 ohm loads. It even has a very nice phone stage as well as one balanced input. There is also a set of preamp outputs to run a subwoofer.

We love the value and overall sonics the Standard offers but wanted to make it even better at a reasonable price. In our mod the following is done:

• The coupling capacitors between preamp and amp are replaced with Auricaps.
This results in better resolution and tighter bass.

• All input op amps are bypassed.
This results in a reduction in grain from top to bottom. This is a big sonic improvement over the stock amp.

• We replace the wire from the amp board to the speaker terminals with Straightwire high purity copper wire. This results in better dynamics and greater transparency.

The modified version is a good bit better and we can still offer it at a great deal. For a limited time we are introducing this $5000.00 amp with our $500.00 mod at only $3,890.00 + frt.

The modified version comes with the full 5-year factory LSA warranty and is a superb value.
