Master 3 Hi Output

Firstly - 4OE provided immaculate service. Product arrived in a couple of days. Thank You.
I chose this cartridge as I heard it on a friends system and loved how it had transformed it. We have no components in common so it really was a leap of faith. I was replacing an Ortofon cartridge of similar cost. I have waited a few weeks before writing this review as the cart has evolved as it has run in. The cartridge has not really changed the sound signature of my system in the same way it did for my buddy BUT: the differences are as if my previous cart was delivering a digital sound and the Grado has made my system analogue. Much larger sound stage, brought a warmth to the system that was not there before and Timbre ( I guess there is a clue in the name of the series !). Giving a bit more detail than I had before (not much) but a musicality and richness that I could not have imagined. My old Jamaican pressings (pretty rubbish) of reggae like Third World sound lovely and the Grado enhances the charm of the passing rather than punish it for being less than perfect. Luther Vandross records soar like never before (Grado & Luther the perfect marriage) more recent high quality produced records like Tom Misch and French Kiwi Juice are just impressive. Tracking is very forgiving the cart looking like a plane flying through turbulence while the sound as composed as a sleeping dog. I am now listening to my music and forgetting about the system for the first time.

Master3 Low Output

Still breaking it in but has so far proved itself to be nuanced and dynamic. Bass is deep ... midrange blooms ... treble is smooth and extended. Imaging is pinpoint and throws a wide soundstage. Everything Grado is known for. Plus, Grado / 4ourEars demonstrated thier stated commitment to customer service.

Master High Output 2 Channel

I would like to comment on the customer service at 4ourears.com. I received a response from my question within 10 minutes of my initial e-mail. It was an unexpected, pleasant surprise to have a reply from a Grado: Richard Grado. He was knowledgeable, personable, listened to my situation, and provided options.

I have had this Reference Sonata Cartridge for about 20 years and really enjoyed it. Richard stated that the Sonata could not be repaired. He offered an exchange/upgrade to give back the Sonata cartridge and supply a brand new, latest version model of my choice. I selected the Master3 High Output 2 Channel cartridge. He provided a discount code and the exchange was completed online using PayPal. Easy.

I thought the Sonata was excellent, but this Master3 lives up to the "upgrade" term in every aspect: frequency range, separation, soundstage, clarity, detail, etc. It is very musical and just sings. Listening to every album again for the first time.

Still breaking in the new cart, but so far it sounds very promising! The service was great, and the folks I talked to via email were very helpful and not the least bit pushy about purchasing the product. I guess Grado must have alot of confidence about the products they sell. I have been buying Grado products (cans and carts) over the past 30 years and I have never been disappointed about anything I have purchased from them or one of their retailers!!
