09-18-11: Undertow Grannyring, What tube preamp is this and what is the output impedance?
This just kills bass if you use a 1500 ohm preamp output with a 10k amp input for sure as an example, I have first hand experience. My first project used a tube preamp like this and I put in Mundorfs back in 2005 later to find out the Solid state amps I had were REALLY low input impedance and were not driven full range due to the combination. Very dead bass, and does not go to the deepest 20 hz its rated at for sure.
I am sure most will say that at "Least" a 10 times difference is necessary. I will say 15 to 20 times is even better.
Now with SS amps I try to keep it 20,000 ohm plus input even more is better like 33,000, 47,000, 100k. Then you have run of the gamut for all preamp choices regardless how high the output impedance gets.
I also switched up preamps due to this problem years ago, now I use a Preamp with as low as 300 and 600 ohm. Some others I have seen like Conrad johnson preamps have super low output impedance some have as low as 50 ohms which will basically drive anything.
But many tube preamps have really high output impedance in the 2000 ohm range, which kills the low frequency on some amp combo's and you need anywhere in the 30k to 100k range to make them work from one end of the frequency balance to the other. Undertow (Threads | Answers | This Thread)
