Wharfedale is one of the oldest and most revered names in British audio, with a legacy stretching back to 1932. Their philosophy has always been to make true high-fidelity loudspeakers accessible to a wider audience. They achieve this by combining classic design principles with innovative, proprietary driver technology. Their modern designs retain a sound signature known for its natural tone, robust bass, and engaging musical presentation.

The Diamond 225 is a highly acclaimed bookshelf loudspeaker from Wharfedale’s famous Diamond series. It features a unique slotted bass port (known as the “Slot-Loaded Distributed Port”) which dramatically reduces distortion and standing waves, allowing the speaker to be placed closer to walls while delivering a clean, powerful, and deeply extended bass response. The Diamond 225 offers outstanding high-fidelity performance for its size and price.

The best stereo dealer in NYC, especially if you’re looking for analog equipment. Steve M. is down to earth and very easy to talk to. He is an industry veteran who really knows his stuff and is full of great advice and options no matter what your budget is.Posted on Google![]()

I first went to In Living Stereo in 2010 or so with a modest budget and walked away with a used Rega P5, new cartridge and a phone stage. Later I got Prima Luna integrated amp then Dynaudio Focus 350 floor standing speakers. Eventually, as time has gone by, I upgraded to a Leben 600x, Leben phonostage and Devore Super Nines. As I built up my system bit by bit, Steve Mishoe and Steve Cohen have guided me to a place where I am truly satisfied. I can't thank them enough! They have great taste and can work with any budget. I trust them implicitly and am thankful that a place like this is here in New York City. Highly recommended!Posted on Google![]()

I have been a faithful customer of In Living Stereo for over the last ten years and believe it is a must-visit even if you are not a hardcore audiophile. First, hands down, the store has the best audio equipment in terms of sound realism, price, durability, and aesthetics. (Note that they don't carry video equipment.) Second, the store is owned and operated personally by Steve M., whose knowledge and attention to detail are unmatched. Steve gives you personal attention, helping you select the best equipment in your price range that meshes and achieves the best collective sound possible. Importantly, Steve doesn't skimp on the details and matches, for example, speaker wires, interconnects, and sound conditioners to complement cartridges to turn tables. Finally, Steve is an extremely nice and honest individual, singularly focused on making sure you're happy with your purchases for years to come. As an added bonus, he listens to all types of music -- and is happy to audition the equipment with any music you bring.Posted on Google![]()

My old amplifier shorted out and stopped working. Every amplifier I had since I was a kid was either a worn hand-me-down, or thrift store finds. I finally have enough money to invest in something nicer. I stoped by In Living Stereo, and Steve showed me a bunch of different options for an amplifier. He was was super helpful with all my questions. I've never had a good Amplifier despite collecting records for over 20 years. I looked at getting a refurbished vintage amp, but found that most prices were the same as a new one. With Steve's help, I picked up the Rega Brio, and my records have never sounded so good. Even music streaming sounds so much better. I highly recommend stopping by and talking stereo equipment. You never know just how good your collection can sound.Posted on Google![]()

I walked into In Living Stereo as a beginner audiophile and was greeted by Steve who walked me through various speaker brands and educated me on buying high quality speakers. The store is amazing, a well curated selection and really cool listening rooms. He let me listen to a bunch of the high end speakers on the floor. He ended up giving me a great deal on a floor version of Dynaudio speakers, which are my first pair of high fidelity speakers. Steve was super helpful and FaceTimed me to help me set up the speakers at home. Highly recommend!Posted on Google![]()

I purchased two great sounding systems - and learned a ton about hi-fi - from Steve over the years. It is a joy to listen to records on world class equipment at the In Living Stereo showroom.Posted on Google![]()

I was looking for a turntable and a pair of speakers. Steve set up a couple of systems for me to listen to and I was able to compare them (Spendor and Devore speakers). He was knowledgeable and patient. I also a got chance to listen to the G.I.P. horn speakers. It was like the musicians were in the room with me, they were truly amazing. Too bad G.I.P. is way outside of my price range. I had a great experience.Posted on Google![]()

Steve was very helpful in teaching me about stereos and what to look for in audio equipment. I didn't have a huge budget but it sounded great, even better than I expected! He showed me the Rega Planar 3 turntable and the Dynaudio bookshelf speakers.
