Modwright PH 9.0

Tube Phono Preamplifier

“I am not exaggerating when I say that this latest phono stage from ModWright may just be, pound-for-pound, the most significant achievement in performance per dollar that ModWright has yet achieved.” – Greg Weaver, PFO


Tonality and texture are rendered with remarkable accuracy, substance, and faithfulness across the entire audio spectrum, giving the PH 9.0 one of the most authentic voices I’ve heard under about $6000.”
Greg Weaver, Positive Feedback

The PH 9.0 takes the reference performance of the PH 150 tube phono stage to a level of performance that belies its affordable price.


The Modwright PH 9.0 retains the flexible MC cartridge loading and gain adjustment of the PH 150 and utilizes similar circuitry. However, the PH 9,0 is in a smaller enclosure that allows for greater flexibility in placement. The 10″ x 10″ x 4″ external power supply can be hidden and 6ft umbilical allow for ease of setup and placement.

Modwright also chose wisely in implementing Lundahl MC step-up transformers, and separate MM and MC inputs. The use of external supply, careful grounding, layout and solid engineering result in an extremely quiet tube phono stage.

The PH 9.0 uses the same (2) 6C45 and (2) 6922 tube complement of the PH 150 and embodies the same tonality, soundstage and musical presentation. Max MC and MM gain of 64dB and 52dB respectively, as well as 0dB, -6dB and -12dB gain adjustment, accommodate a broad range of MM and MC cartridges.

The back panel features one set each, MM and MC RCA inputs and one set of RCA main outs. The PH 9.0 can be fitted with (at an additional cost) fully balanced, transformer coupled XLR main outs. Turntables with two tone arms are easily accommodated, and with an outboard step-up transformer for the MM input, two MC cartridges may also be used.

“There is some real enchantment in the midrange here, as it seems to effortlessly and fluently present that inescapably correct body and bloom one ultimately expects from a good valve preamplifier. Authority through the so-called power range (J. Gordon Holt’s, The Audio Glossary, claims that range to be 200Hz to 800Hz, or from the very upper bass regions into the middle midrange realm), is remarkably solid and exceptionally well-controlled. Its ability to render accurate tonal color and to capture the vibrance and texture of voices while maintaining a remarkable level of resolve and transparency may be unprecedented at this price, and is not markedly dissimilar to the remarkably lofty performance of the PH 150 Ref.” – Greg Weaver, Positive Feedback

  1. Robert Johns

    I have been on the hunt for a good, and I mean actually a very good phono preamp for the better part of two plus years. I have tried several phonostages that have been highly recommended in the audio press, only to find those lacking in “musicality”. The ones I tried were two dimensional in sound, and lacked the ability to draw me into the music. Analog music always has me tap my feet to the music but the ones I tried did not.
    Enter the Modwright PH9.0. This phono preamp was a Godsend and saved my analog set-up. It gave me what I was looking for and what I expect from LP playback; detail, PRaT, that “analog” 3D soundstage, warmth but not overly so but “real”. Bass was tight and highs were extended and clean. Stock tubes were actually very good but I installed a matched and low noise pair of Gold Lion re-issue 6922 tubes and it took the playback level of the PH 9.0 to another level. After buying, selling / trading four previous phono preamps prior to the ModWright I can now finally rest as this is definitely a keeper. If you are in the market for a phono preamp that performs above its pricepoint, has excellent flexibility with cartridge loading and its extremely well built, this is the phono preamp for you. Once you listen to the 9.0 I am willing to bet that you will not send it back. Dan Wright has hit a home run with this piece!
