I recently sold my Jolida FX10 here on the A'gon. I recommend them highly. I used them in a 14x16 home office with stellar results. Never a problem and to get best results one should use high efficiency speakers (mine were generally Tekton 4.5s and Tekton Lore at times). The other thing is change out the stock Electro Harmonix tubes. I had great success with NOS Russian 7189s, Ei EL84s, TAD EL84s. For the 12ax7 I used NOS Telefunkens, Ei, Mullards as well as a Tubestore Northern Electric NOS with good results. In my room I often had a wall-to-wall stage that was nicely layered, good tone, love the EL 84s, fast and punchy, good enough detail, the little thing was just musical and went as loud as I could tolerate. The bass on the Lore was very good. Tight and lively. This amp plays way above its price point, great 2nd system or first if doing a desktop or just starting out with tubes. Really fun little guy.
Jolida Fx10
Last week I purchased the Jolida FX10, not knowing what to expect I was skeptical that this 10wpc integrated tube amp was going to sound so superb. I paired the amp with PSB B25 speakers rated at 91bd efficiency and I wow the sound is practically magical. What a nice little amp and for the price of under $500 wow, great deal!
