Fantastic!!!Apr 13, 2007
This phono stage has a good variety of adjustable settings for gain and cartridge loading. Gobs of gain available. Will work well with the lowest output moving coils, passive preamps etc... Great for recording vinyl to digital and getting proper recording levels. Pretty quiet, a little tube noise (whooshing) can be heard only with the volume cranked way up and nothing playing. Due to the high gain of this phono stage, it's unlikely you'd ever have the volume knob that high with a signal present. Build quality is very nice for something reasonably priced that performs this well. It's a ten pound phono stage with a thick aluminum front panel and a heavy steel chassis. All of the gain and loading options can be accessed via the rear panel without opening the unit.
I love the sound. On the warm side, VERY dynamic. The "slam factor" is the first thing you'll notice if moving up from an entry-level phono stage. Good frequency extension, very solid bass and a smooth high end. With a little tweaking of the gain and loading settings, I can't imagine anyone not being able to get sound out of this thing that appeals to them. Probably not the most transparent phono stage. The mids can sound a little forward and "thick"... I personally like the slightly emphasized richness and ambience in my system. What it does resolve, it does beautifully. "Musical" is an excellent one word description of the JD-9A. Nothing I've heard compares at this price. Always sounds rich, dynamic, balanced and pleasant. Stabile soundstage, good detail, and a nice sense of "life" to the music, slightly warmed up by the "tubey" midrange.
The stock tubes are Chinese Shuguang 12AX7A. They sound a little on the "warm and wooly" side. More neutral sound can be obtained by replacing them with some good NOS tubes or current production tubes like the Electro Harmonix Gold pins. The Electro Harmonix sound even better than a pair of NOS Brimars in my system. I thought they sounded a little "edgy" at first. But, I found after tweaking my tonearm a little more they sound excellent. They seem to improve focus and resolution quite a bit over several other tubes I tried in the Jolida. When something's wrong, you'll hear it... When everything's right, the detail, smoothness and stability of the soundstage is a huge step up from what I was getting out of the Jolida with all the other 12AX7s I tried.
Highly recommended in this price-range. Head and shoulders above "entry-level". Honestly don't think you could beat it for the price, or substantially more...
Retails for $450.00. Got mine at Uptown Audio for a little less shipped and received excellent service.
