“First I will say I really love this amp as in my previous reviews. I have had it about year and half now. It has worked great. However I am having trouble for what ever reason it does not like gold plated pin tubes. I do not get it. I put them in I get pops static. I put in a regular pin tube no issues sounds great. I take that same tube and put into another amp it works fine. i have tried several different tubes same thing.. Made sur pins are clean made sure the pin holes are clean no dice.. I do not know what is going on but it does not like them anymore. I am not talking cheap tubes here either. Anyway I guess no more gold pin tubes for that thing.. sounds crazy but it is fact. I do not get it.”

“I've been looking to complete my audio system (also purchased from Upscale) with a pair of headphones and a headphone amp. I went to my local audio store to audition the headphones I was looking to purchase and to discuss headphone amps. Once again, I was disappointed by their lack of knowledge and willingness to see how I could set up a headphone amp and headphones with my current system. Uncle Kevin says to patronize your local audio store, and I did, only to be told I would have to spend at least $5k on a good quality amp and system after I told them my budget was around $3k. After my frustration, I came home and called Upscale. Richard O'Neill answered the phone. He asked questions about my system, the headphones I was looking to purchase and my budget. He took the time to see what would be the best set up for what I have. He recommended the Feliks Audio MK II which would be a great complement to the Focal Clear Mg headphones I would also purchase. He also explained to me how to set it up with my Mobile Fidelity integrated amp. The experience of working with him was beyond reproach. With cables, everything came a little above my budge, but for me, that was fine. I was very excited to receive the amp and headphones. It was a breeze to set up. It's my first tube amp as well. First track - Janos Starker playing Bach's Unaccompanied cello suites, 45rpm, Analogue Productions. The clarity of the tones and the openness of the sound brought tears to my eyes. I could hear sounds I never heard before. Next up - the voices of Joni Mitchell, Taylor Swift, Billie Holiday, Billie Eilish, Janis, Elton John, Billy Joel, etc. were as if I was in another realm. The jazz of John Coltrane, Fred Hersch, Dave Brubeck, etc., were like I was sitting in a club. I cannot say enough about this amp and headphone combination. I feel like I'm in another world when I am listening to the Focals with this amp. I also cannot say enough about the customer service and knowledge of those at Upscale Audio.”

“This is a follow up on my previous reviews. Even though this is an entry level Feliks Audio amp it is a great tube amp. I have a big stash of new and NOS tubes. I rotate in my other amps then rotate tubes in this amp. I am careful not to get carried away with this not to damage it. I finally put in the 6H23 / 6922 Type 3 tubes and listen for many hours. I understand very well that this is subjective to all who have tubes. First in my opinion if you want to get into tubes this is for you for the money. Grab it. Also with these tubes the combination seemed to be great now this is just my opinion. The stock tubes are fine though. I have other amps and I play around with all my tubes. This my favorite amp for the money. Again just my opinion as tubes are subjective. Uncle Kev has a video on this amp on his web site. I thought I will try it. Thanks Uncle Kev and Merry Christmas (2023) to you all your family and workers. What a great job they must have with all the wonderful equipment !! I would probably sleep there! LOL!”

“I love this amp. After a couple of hours of listening everything opened up nicely. The Echo MKll is very smooth with nice detail and separation. If this is the low end of the range I can't imagine what the higher end of the Feliks Audio range sounds like.”
