Go for the best tubes you can buy from Andy. You won't be dissapointed. You might consider re-tubing your mono's next. Ask Andy for his advise. I got lower noise floor, holographic sound stage and improved bass extension right away. Everything improved from there over the next month until they were fully broke-in.
tube preamp please, replacing counterpoint sa7
i just purchased a counterpoint sa7 tube preamp to replace my 6 year old nad 705. it is not living up to my expectations, the bass is extremely lacking, and with no tone controls i can't help it out (allthough i always left them flat on the nad with no trouble)- can anyone reccomend a decent tube pre in the 300-400 dollar range? phono preamp is a must- thats why i bought the counterpoint. i heard the phono preamp was spectacular, which it is, except for the weak and muddy bass. could the problem be solved with any mods or tube replacements?
