Reviews

Sound Clip -  Out of Africa  by John Barry 

SS-4772 - I just want to say " WOW WOW WOW" After a few days of listening to records on this amplifier, the sound coming out of my pioneer HPM"S is so smooth and warm.  The customer service is in the highest standards. They kept me informed durring the build of the amp. Thank you. Willy S. (Colorado)






 
Jim - I am sitting and listening to your amp- it is all warmed up and playing a new "Tommy" LP.   The amp sounds just stunning: very powerful and dynamic, detailed, open, huge bottom end.  I will say that bypassing the presence and treble controls raised the volume and lifted a veil.  I have listened to and owned lots of amps and I am amazed by the value in this one- it could compete with  amps costing three times as much.  Once warmed up, it was immediately and completely involving.  Please feel free to use me as a reference for this fine amp.  Best regards, Jeff S. (New York) 

SS-4772 - Dear Frenzel Tube Amps, Thank you very much!!! I received it today, it's amazing!!! Sounds great!!! Will recommend you to my friends.  Klepatskayavi (Russia) 

SS-4772 - Thanks Jim, The amp sounds absolutely amazing, this is the best sound I ever had at home. Fantastic! Darek O. (California) 

Dear Mr. Jim Frenzel, Your SS-4772 Super Stereo amplifier is nothing shy of epic. I am so thrilled, so happy, so blown away by your amplifier.  Thanks for integrating old school technology with new school systems compatibility.  This thing works great with my Apple iMac, my Samsung BluRay DVD, and my Samsung TV - and with no preamp required for these devices! It also works fantastic with my old school Technics 1200 Mk2 turntable.  My pristine 70's vintage Pioneer CS-99A speakers did a instant hand shake with this amp as if it was an old long lost friend. I am so pleased with  how this amp clearly transfers  digital iTunes music to a whole new world of old school analog tube sound.  Maybe it's the old school technology with a tiny bit of new mixed in to it... whatever the case my be, you have hit the nail on the head.  You have designed an old school analog tube amp that will transform the sound of digital recorded music to the way it should sound.  I'm amazed, I'm blown away, and I am so happy I chose your company to build my amp.  I received my amp last Friday. I have locked my doors, turned off my phones and email, and signed myself out from the outside world for a week while I process the prowess of this amp. A great super clean sounding tube amp at a price I could afford. Way to go!  Sincerely, John K. (Florida)


SS-4772 - Hi Jim, Thank you again for this wonderful amp. The best I ever had. I sit now and listen for hours, something I haven't done in decades..Darek O. (California)
 
Hi Jim - I just wanted to let you know that I have received the 4772 amp today. Man, does it look beautiful!!!To me, it is a piece of art, just like the other amps I have from you. I was impressed by it's size, it is bigger than I thought and sometimes bigger is better :-) It seems to have survived the journey over the Atlantic well. I am really happy Jim, thank you so much for building it for me! You guys at Frenzel are the best. I will get back to you for more orders soon..(thinking of the twin deluxe and the champ sportster at the moment..and I have some ideas that we might get to work) and oh yes, that mic-preamp we were discussing some time ago! Only a fool would be satisfied before he have all the products you have to offer. :-) Honestly, your amps warm my heart, I am not just buying an amp when I buy from you, it's so much more and so much better (and definitely more value!!)! Once again, thank you so much!! Anders H. (Switzerland) 

Love the amp Jim, great sounding piece of equipment. Nothing sounds better than a Stereo Tube Tape Echo into a Stereo Tube Amp! I have found tone heaven. Thanks again, Kevin M. (Nebraska) 



Hey, thanks for making such a great amp and excellent customer service. Jeb. B (North Carolina) 

Jim,   Christmas in May!  I received the amp last Friday and unpacked it Saturday.  It is absolutely the most beautiful piece of stereo equipment that I have ever seen...   George O. (Texas)  


Hi Jim - Received my new amp in good condition. Couldn't resist taking off back cover to check out the wiring. Very impressive. Have amp hooked up to some big old speaker cabinets that my father made back in the 50's or 60's. They have big 15" Jensen speakers, tweeters, cross-over networks, etc. Old school. I've refinished the cabinets, which were in storage for decades, and they look pretty good. Have acquired a turntable and dusted off my old vinyl jazz records. The whole setup sounds great - can't beat the warm tone of vinyl records and a tube amp! Anyway, amp is great. Thanks for producing a quality product. Phil T. (Florida)


Hi Jim - Hope you are well, many thanks for building this awesome amplifier for me, it arrived safe and sound thanks to the excellent packing. I had never heard one but took a chance due to the great reviews for your amps. on your website and elsewhere. I'm very glad I did too, the power, tone and clarity is just amazing and I can't believe how effortlessly it drives the Kef Chorales, they've never sounded so good even without new crossovers!  The Marantz CD63se sounds fantastic through the amp. I'm now thinking of buying a Musical Fidelity M1 DAC to further improve the cd analogue output for the amp., I think it deserves the best possible signal. Nice to see the 1% tolerance resistors that's real quality, they look like 2w carbon to me? Everything looks just as good inside as out, very neatly laid out, you are right to be proud of your products! Thanks again for building it for me, I wouldn't hesitate to recommend you to friends and family. Pete C. (United Kingdom)
