The Nobsound 6P1 is a very basic, attractive looking class-A integrated tube amp with modest power output that''s suitable for running one music source and a fairly efficient pair of speakers. The overall quality of the amp is impressive considering the modest price. The package arrived within about a week, fully intact, and was very well protected. Basic installation couldn''t be much simpler - install the tubes, plug it in, hook up speakers and music source, and you''re in business. I even liked the speaker connectors they use. Some sort of a schematic or instructions would have been nice, but it''s all pretty intuitive, and I''d guess they''re assuming that the buyers of an item like this have prior audio experience.
My first impressions of the sound of this amp were quite favorable considering the very low cost. The amp replaced an excellent pair of Dynaco ST70s that were run as a separate mono blocks. The Nobsound amp was purchased as an interim amp while I serviced my 50+ year old Dyna amps, so I didn''t want to spend a lot, but also didn''t want to abandon the level of fidelity I''m used to. The Nobsound 6P1 is priced lower than many lesser solid state amps and receivers, so I opted to give it a try, and am very happy with it so far.
This review is early on in my experience with the Nobsound amp. I''ll update as needed as I get more time with it. Expecting the Nobsound amp to perform at the level of the Dynas is a tall order, and it doesn''t, but it immediately sounded pretty darn good. The output is pretty modest at 6.8 watts per channel, and doesn''t have the power and punch of my Dynas, but they sound so much better than a comparably priced solid state amp or receiver. The initial sound was a little darker through the mids than my Dynas, and the bottom end isn''t as authoritative, but the mids did open up more as the amp warmed up and the components burned in. I''ve ordered some vintage tubes to experiment with in the preamp section, but for now I''m kind of amazed at what I got for what is really a very low price for a Class-A tube amp. Good tube amps can cost thousands of dollars, but the little Nobsound gives you a nice taste for a couple hundred bucks. It''s a really nice little amp. 5-stars for value, 4-stars for performance (edit - I went back and gave the performance 5 stars...it''s just too good for the money to leave it at 4 stars....it''s not world class, but is the among the best sound you can get from an amp in this price range.)
Update: So I''ve spent quite a bit more time with the little Nobsound amp, and I''m still pleased. As the components burn in, the sound has opened up nicely through the mids and highs. The addition of a pair of vintage RCA 6SN7GT tubes made a fairly notable improvement in clarity in the mids also. The modest power output is enough to suit my needs, but I don''t play the system loudly very often. If you like to crank your system, you may find the amp''s limits in a hurry, but aside from the known limits of the output, this is a nice amp. Highly recommended if you don''t need gobs of power, and you want clear musical sound with a good sound stage at a budget price. (additional edit - it took me two years to rebuild my old amps, and the Nobsound was flawless....not even a tiny glitch. I''m so impressed with the value and performance. It''s been a great purchase!)
Bonus update: Once my old Dyna amps were finished, I put the Nobsound amp up for sale. The guy who bought it was a seasoned audio lover, but had never had a tube amp. He hooked it up to a pair of older Klipsch speakers, and called me back immediately....he was totally surprised how clear it sounded. There''s a new tube lover in the world thanks to the little Nobsound amp. (I wasn''t surprised at all!)
