Upgrading specific components in a tube amplifier

Thank you for your replies. 

The audiophile gentleman I was talking about upgraded the capacitors to Arizona Capacitor Blue Cactus and resistors to Audio Note Silver Tantalum/Niobium 2 watt. Since this person is to specific I was wondering if the components had a significant and positive effect on the sound overall. 

I am still reflecting on purchasing the Yamamoto VT-52 amplifier and I have been told that they are absolutely astonishing but the tube sockets could be improved, that's why I also asked about those. 

Many of you mention tube rolling and I can't wait to indulge in this exciting activity, even though it seems it won't be as cheap as somebody claims. The Yamamoto amplifier I'm looking at uses the exotic and rare VT-52. 

Perhaps I should try to restate my question and present it in a hypothetical way.

If I were to switch resistors to Audio Note Silver Tantalum/Niobium 2 watt, change the output capacitors to Audio Note silver foil capacitors and change the tube sockets to Audio Note aluminium/steatite bases in a Yamamoto amplifier. Would it have significant changes to the presentation of the music? Please bear in mind this is a thought experiment. 

Once again thank you very much for taking your time to write so thorough responses to my inquiry. 

 

Are you doing it because you want to have fun and enjoy the hobby?  Are you making a repair and it is an opportunity to possibly improve a short coming? Are you dissatified with the piece of equipment?  [Would it be cheaper to sell the gear and invest the money (including what you might spend on parts and labor) into something better.  Can you afford to write off the investment in the equipment you are modifying?  (Somethimes it can be real hard to sell modified equipment.)]  

Relevant and necessary reflections that I believe one should carefully consider oneself before proceeding with these major adjustments.

Figure out which resistors and caps you're looking to upgrade, post the values and where they are in the circuit, and current brand, and you'll get some good recommendations.

As I mentioned I'm considering Yamamoto Sound Craft VT-52. It is supposed to be an astonishing amplifier made of high quality craftsmanship.

After reading the article of switching components here and there, I started wondering how that would work on a Yamamoto amplifier. II have a pair of Audio Note speakers, entry-level, although they may be upgraded to AN SPe/HE very soon. Then I started to play with the thought of changing bits of Yamamoto to Audio Note components (capacitors, resistors and perhaps tube sockets as I heard Yamamotos aren't the best) to see if you could improve the amplifier a tiny bit. Perhaps it could also promote synergy with my speakers, who knows... 

The intent is not to have a Yamamoto amplifier that becomes a clone of Audio Note but rather, identify if there are components within the Yamamoto circuit that could be improved. 

Thank you all for all of your insights.

I have read numerous articles, reviews and threads on various forums that confirms the high quality of Yamamoto and I don't think at all there would be a reason to change anything at all. It was just a thought experiment to get an idea of the possible outcomes of changing components as capacitors, resistors and tube sockets. 

You're looking at adding quite a bit of silver with the Audio Note components you specified in your post. I'd expect this may thin out mids, bass, less warm presentation. I have no issues with silver, just needs to be balanced with copper. On the other hand if existing presentation excess warmth or dark sounding silver could be just the thing.

This is quite interesting. It seems that a lot of people strive for an all silver situation in Audio Note forums, but somehow I'm starting to believe that silver might have a too bright, clean and neutral resolution, whereas I prefer a much more deep, flavorful and colored sound (without it being too dramatic, rather more natural and romantic if one can say that). 

I have been considering the OTO SE amplifier, which is widely regarded as an excellent choice, and I can certainly understand why. I had the opportunity to listen to it recently, and I really enjoyed its sound.

That said, there is something I am trying to better understand.

The OTO SE is undoubtedly a great amplifier, but it does not, for example, include a completely negative-feedback-free signal pathway. To achieve that, one would need to look at the Jinro or higher-tier models, which come at a significantly higher cost. I have also contemplated investing in a higher model, but I often find myself considering how many concert tickets and vinyl records I could purchase with that amount. Ultimately, my passion for audio is rooted in a deep love for music.

Recently, I have come across smaller manufacturers, such as Yamamoto and Audio Tekne, who seem to produce high-quality amplifiers at a different price point compared to Audio Note. I fully appreciate the immense costs involved in running a company as comprehensive as Audio Note, which manufactures all its components in-house and offers numerous variations of each amplifier. Their reputation and craftsmanship naturally contribute to their pricing, which I completely respect.

However, I wonder if it might also be worthwhile to explore the work of dedicated, passionate independent producers, particularly those in Japan, who bring a similarly high level of artistry and commitment to their craft. I hope it makes sense.
