Hi Pubul57,
The reality is we`re both obvious exmaples that either way is fine,it`s really no big deal. If Botit gets a tube amp first then an appropriate speaker his chances for sucess are as good as mine were. He will do well. |
Speaker then amp or amp then speaker,'either' method works out . In the end they both have to match, chicken or the egg.I based my system on a move to a SET amplifier and it worked out fabulously, you just have to have a well thought out plan.

Mike makes a good point.I prefer tube amplifiers, BUT be certain your speakers will be 'compatible' or you`ll be disappointed and likely blame the tube amp. |
Mikirob,
Your example is my historical reality! My first high end systems for competely SS gear.Over time I was introduced to tube amps and preferred them by a consideable degree.
Once exposued to the genre of SET amps if was all over,I found them much more natural and closer to what I hear with live music.
I bought a 300b amp built my system around it and it exceeded my high expectations. I enjoy the best music reproduction I`ve ever had(by far). Absolutely either a amplifier or speaker can be the building block for an audio system. I know I`m not the only one who has sucessfully done it this way.
Best Regards, |
I don`t want this to disintergrate into another tube vs SS (again, sigh)I freely admit amp'or' speaker first appraoch can work out well.
When it comes specifically to SET amplifiers you 'most' often will begin with the amp you like and just find a good efficient-easy load speaker to match.Fortunately on the current market there are many to choose from. |
Atamsphere,
What you explain in technical terms make plenty of sense. Some would say you`re obviously bias toward tubes(the products you build and sell). How do you debate with equally renowned SS builders i.e. Pass,Gryphon,Vitus,Boulder.Soulution etc. who would I`m sure insist their products produce music as'real' as any tube component and possibly better? My ears lead me to tubes but I could`nt make an arguement with a technical viewpoint as you are able to do. |
Mikirob,
Oh I very much trust my ears(there`s no better way) That`s how I got to SET amplifiers. My question for Atmasphere was academic in nature,tube amp designer vs competent SS designer.

Jwm,
I believe you are correct for the most part,but it really depends on the speaker you intend to drive. I do 'think' that some lower power SET amplifiers(I think my 300b amp is one example)operate without'any' negative feedback at all. This may be possible due to their inherent linear character. If this is the case then of course appropriate speaker selection is a must. I`ll check with the builder of my amp to be sure. |
Jwm,
Israel Blume(Coincident) confirmed the Frankenstein amp does`nt use any negative feedback, global or local. He said it is a zero feedback circuit.

When all is said and done I believe the need/advantage for feedback comes down to amp design and certainly the speaker involved. Some speakers simply don`t need the additional damping feedback provides, other speaker types would benefit.
The proof is in listening, my amp has no loose bass or undisciplined problems,there`s good control,articulation and nuance, so feedback is`nt always mandatory. In the end what matters is proper amplifier-speaker compatability.
Regards, |
It has gotten some what off topic yet very interesting and informative,good thread IMO.
Atmasphere do DHT tubes behave differently from IDHT(Pentode) type tubes and would their response to feedback be the same? is one type more linear than the other? could that explain why some SET amps with DHT tubes can perform well without the need for feedback. Suprisingly the Yamamoto DAC I use is SS yet the builder uses zero feedback(he claims even 1 db of feedback is noticeable in the circuit).
Regards, |
Atmasphere,
I 'suspected' true triodes are more linear thus they don`t need to rely on feedback.Thanks for taking the time to explain the instrinsic differences between triode and pentodes, very educational.
