The least expensive of Telos line, the 150's MSRP is close to USD $9000 MSRP. Nevertheless, If you could one get in the used market, don't even hesitate to go for it. The sound is fast, detail, refined, without any listening fatigue. Tremendous soundstage and extension.

It is very sensitive to power. You will hear clearly every power cord change and/or power conditioner change.

Contrary to some Goldmund owners, this Telos 150 work well with tube preamps. However, any noisy tube / lesser quality preamp will be exposed like under an magnifying glass.

IMHO, near reference quality at bargain basement price.
