Hi,

However, even if you did succeed to preserve dynamics in your line-level transformer then the LF cut off of this transformer will “get” you. The solution is very simple: do not run any transformer attenuators within a really LF capable installations….  I said the “LF capable” and I wonder… how about the LF modulations that must be within any amplification channel? Absents of real bass within amplifier means no properly auditable HF, no proper harmonic modulations… no Sound as far as I concern. (Remember, I did not advised to high pass the HF channel of the supper Milq).

Would it be theoretically possible to bult a properly operating full-range capable innerstge transformer? I did not see any. I am sure Bud, Chris from UK or Torthen if they read it would be violently disagree to my assessments, but I do agree with myself: a line level transformer has more problems then solution, beside that fact that it never sound LF capable, or something that I usually call “good only for Lowther-based systems”....

... there is no really LF potent/transparent line-level transformers.



I wonder, which specific line level interstage transformers have you tried, it would have to be ALL of them in order for your statement "there are non" to hold.

For reference, the current generation S&B TX-101 (Line Transformer, also in an experimental "high level" tube interstage version which may or may not become commercially available) and TX-102 (Line Level Attenuator) are free from any significant (> 0.1db FR deviations or > 5 degrees phaseshift) observable issues down to 10Hz, when driven from a 1k or lower source impedance.

At sensible levels (1V RMS) any distortion is sub -100db with only low order components (<= 5th, 3rd dominant) as far down as that too, in fact to measure any distortion on the transformer you need serious levels at very low frequencies and some really good analysis gear.

So, at least in commonly observable and observed terms and when used as intended the S&B line transformers are notably more capable at low frequencies than your LF OPT's in the Super Milq.

If they can be mada better in areas currently overlooked, please let me know, I'll broach it with JB.

But, what specifically do you object to in these transformers?
