Modification Descriptions

-Power Supply, Connectors and Analog output stage Upgrades
($450 Installed, FREE return shipping via Fedex Ground)

Replace stock IEC connector with Furutech Gold plated IEC connector for power inlet.

Improvement: Better voltage integrity and better grip on power cord.

Replace stock rectifiers with RAM ultra low impedance custom handmade versions

Improvement: Replacing the stock, noisy diodes with our handmade ultra low impedance diode bridges bring increased resolution, removes all grain and grit and better bass qualities. We reworked the bridging topology to allow for far less noise.

Replace all capacitors in circuits Rubycon ZA/ZL series capacitors.

Improvement: These capacitors are much more open sounding, very neutral and have more speed than any other cap on the market. We have compared Blackgate FK/N, Panasonic FC/FM, Nichican Muse, and Os-cons and they are not in the same league.

Replace the input coaxial RCA and Analog Output RCA connectors with the new WBT NextGen High performance RCA connectors.

Improvement: These are an eddy-current free design using very little metal and offer more of a "straight peice of wire" sound, rather than the grainy, itchy sound from the metal bulky stock connectors. We have compared other aftermarket RCA's from Vampire and Cardas and they exhibit grain in the music when compared to the WBT Nextgen.

Rewire the WBT NextGen RCA's with Audio Consulting Silver wire and Cotton tubing.

Improvement: No teflon or plastics used around the wire, were we hear frequency shift and imbalances in the sound. This wire/cotton combo is the most neutral/natural sounding combo that we have heard!

We replace the stock Analog Output Coupling Capacitors with the LeClanche NOS PIO type caps and REMOVE ANALOG OPAMPS!!

Improvement: These are the most natural and neutral sounding capacitors we have heard for signal coupling and really opens up the soundstage and presents instruments in a very scary lifelike manner. We have compared every cap on the market, such as Auricap, Mundorf silver PIO, sonicaps, etc.. and every plastic or poly cap sounded unbalanced and had a "synthetic" sound to it. Neutral/Natural tones are the end result from using these caps in this great little DAC. We remove the Analog output stage op-amps completely for a minimalistic signal path approach and notice increased transparency, and resolution and removal of all grit for the unit.

Let me begin by saying that I like Doug Jesse's work. I have several RAM-modded components that I am very happy with. So I may not be the most objective reviewer, but here are my thoughts anyway:

I've been running a RAM-modded Lite DAC-Ah in my system (I have actually listened to it in a couple different systems) for almost two weeks now and I am mightily impressed. I had the stock unit for some time and the modded version is a significant improvement. Details, transparency and soundstage are all dramatically improved.

I listen to a lot of jazz, especially piano trios and female vocals. I notice a much better sense of the music...cympals are crisp, drum brushes are eerily "there." Listening to Blossom Dearie's "The Party's Over" from the Comden and Green songbook, I was immediately struck by the wider soundstage. The song opens with a wonderful instrumental trio of bass, drum and guitar (the late, great Barney Kessel, I believe). Guitar and drum off to the right, big, fat, rollicking bass on the left. I could literally hear the strings being struck on the bass. When Blossom comes in front and center, it sounded like she was in the room with me.

I have listened to a lot of the contenders in the $1,000-$1,500 range and this DAC stacks up against any of them and is better than most. For the money it is hard to beat. I highly recommend it.
