Vinyl System Upgrade
02/21/20 at 00:28:00
 
I have been planning to upgrade my vinyl playback chain this year, to cap off my system. Before I move forward with a new turntable & cartridge, I started looking for a tube phono preamp with MM & MC capability that was quiet, dynamic, and flexible.

About 3 years ago while attending the Capital Audio Fest I spent a lot time listening to a system which included Daedalus speakers, a VPI Signature Prime TT, and a Modwright Ambrose tube amp & pre. Included was the $7900 Modwright PH 150 phono preamp. Wow the sound was just glorious, but the way beyond my wallet capabilities.

Fast forward - last year Dan Wright, the man behind Modwright, came out with a less expensive tube phono preamp, the Modwright PH 9.0. A friend picked one up and I have been over for several listening sessions. It is a relatively compact MM & MC capable two-box design with on the fly MC loading & gain adjustments, a stereo/mono switch, and utilizes two 6C45 & two 6922 tubes. It's one of the quietest tube phono preamps I've heard, absolutely no hum & a black black background. Plenty of MC gain for my Dynavector 20X2 low output cartridge.

Anyway, I should have my new PH 9.0 in a couple weeks. More info to follow.

I'm very interested in hearing what you think about the PH 9.0?

Right now I don't have time for a full review. It's a keeper!

The PH 9.0 sounds very similar the Modwrights top of the line PH 150 Reference Phono. It's very, very quiet I hear absolutely no noise through my Decware ZROCK2, CSP3+ preamp and ZMA equipment powering the Caintuck Lil 15 speakers which are very sensitive. Tracking noise of the stylus/cartridge is virtually non existent on decently pressed vinyl.

Exceptional tonality and realism with the tube output of this two box unit. It's a very flexible phono which can accommodate a wide range of cartridges, MM, lo MC, mo MC & ho MC. It has a decent number of MC load options and gain settings which alavailable on the fly (clearly labeled adjustment dials & toggle switches on the front panel). I have heard a lot of very highend analog set ups with mega bucks phono preamps over the years. The 9.0 comes very close the very best sound for a reasonable cost IMHO.

BTW,

I have a Triode Wire Labs (TWL) custom cable coming that connects the PH 9.0 phono chassis to the separate power supply. Pete's power cords are really good, so I thought I'd try the out to see there any improvements.

I'll report back after some time with the new cable.

Nice, thanks so much for sharing! I love my my ZP3 but the PH 9.0 has grabbed my attention.

I've heard the ZP3 at Decfest but have never lived with one. I like the versitility of and MC loading options on the PH 9.0. Both excellent performers.

Nevertheless, as many things it's necessary to clean, so I want to tell you about this invaluable source https://theguruchoice.com/record-players/best-record-cleaner/ where you will definitely be able to find record cleaner that you might use in daily life for keeping your vinyl in tghe cleanest state.

Well with the amazing SQ of my MWI modified CXN V2 DAC/streamer I decided to opt for Dan's brand new PH 9.0 phono preamp upgrade. Just got my unit back with new Lundahl transformers and XLR outputs.

The Lundahl transformers take 100 hours to settle in, so I'll be splitting listening time between streaming music and vinyl listening over the next few weeks. Too bad there is not more time in the day😁.

I'll report back on my listening impressions once everything is properly burned in.

While my analog front end has difficulty keeping up with my vinyl these days, I decided some tube rolling was in order in my ModWright PH 9.0X phono pre. The pre uses two pair of tubes 6C45's and 6922's or equivalents.

Since the NOS '74 Reflector single-wire, silver shield 6N23P tubes sounded so glorious in my modded CXN V2, I thought I'd try a pair in the PH 9.0X. More to come when the tubes settle in.

Crap. Lots of tube rush with this pair of 6N23P tubes, ugh. Back to my sterling Amperex 6922's from Andy at Vintage Tube Services. BTW Andy's tubes sound glorious and are rock solid.

 I would second that about Andy's service/products. Haven't talked to him in some time, but yes, the tubes he sells are the best of the pack.
